2 months back at trading (update) and some new questions
Hi all, I posted a thread back a few months ago when I started getting seriously back into trading after 20 years away. I thought I'd post an update with some notes on how I'm progressing. I like to type, so settle in. Maybe it'll help new traders who are exactly where I was 2 months ago, I dunno. Or maybe you'll wonder why you spent 3 minutes reading this. Risk/reward, yo. I'm trading 5k on TastyWorks. I'm a newcomer to theta positive strategies and have done about two thirds of my overall trades in this style. However, most of my experience in trading in the past has been intraday timeframe oriented chart reading and momentum stuff. I learned almost everything "new" that I'm doing from TastyTrade, /options, /thetagang, and Option Alpha. I've enjoyed the material coming from esinvests YouTube channel quite a bit as well. The theta gang type strategies I've done have been almost entirely around binary event IV contraction (mostly earnings, but not always) and in most cases, capped to about $250 in risk per position. The raw numbers: Net PnL : +247 Commissions paid: -155 Fees: -42 Right away what jumps out is something that was indicated by realdeal43 and PapaCharlie9 in my previous thread. This is a tough, grindy way to trade a small account. It reminds me a little bit of when I was rising through the stakes in online poker, playing $2/4 limit holdem. Even if you're a profitable player in that game, beating the rake over the long term is very, very hard. Here, over 3 months of trading a conservative style with mostly defined risk strategies, my commissions are roughly equal to my net PnL. That is just insane, and I don't even think I've been overtrading. 55 trades total, win rate of 60%
33 purely directional trades - 57.5% win
18 long call or long put positions, +692, 55% win
15 call or put verticals, -121, 60% win
22 neutral / other trades
13 iron condors, +345, 77% win rate
7 strangles, -163, 71% win rate
1 straddle, -310, 0% win rate
1 butterfly, -83, 0% win rate
PTON call purchased and held through earnings, sold the morning of announcement +410
Trading the range on the daily chart in GLD from 158 up to 165, a mix of various calls +245
NKLA 30 put purchased before the close on the day it went north of 100, just a pure fade +215
EWZ 22/26 strangle that I held just way too long as it beat me up day after day from May 20-Jun 3, -316
ZM pre earnings vertical, fading another 2 SD move (the day it hit 200 for the first time). Was expecting a post-earnings selloff given the magnitude of the up move. Stock basically hasn't had a down tick since. Max loss -247
EWW 29 straddle, put on around the same time as the EWZ strangle. Rolled from Jun to Jul to no avail. Out at a -310 loss.
This is pretty much where I expected to be while learning a bunch of new trading techniques. And no, this is not a large sample size so I have no idea whether or not I can be profitable trading this way (yet). I am heartened by the fact that I seem to be hitting my earnings trades and selling quick spikes in IV (like weed cures Corona day). I'm disheartened that I've went against my principles several times, holding trades for longer than I originally intended, or letting losses mount, believing that I could roll or manage my way out of trouble. I still feel like I am going against my nature to some degree. My trading in years past was scalping oriented and simple. I was taught that a good trade was right almost immediately. If it went against me, I'd cut it immediately and look for a better entry. This is absolutely nothing like that. A good trade may take weeks to develop. It's been really hard for me to sit through the troughs and it's been even harder to watch an okay profit get taken out by a big swing in delta. Part of me wonders if I am cut out for this style at all and if I shouldn't just take my 5k and start trading micro futures. But that's a different post... I'll share a couple of my meager learnings:
Larger bid/ask spreads make it almost impossible to trade the higher priced names, even if you have a correct assumption. I have traded some bigger underlyings during this time like LULU and NVDA. They are just tough fills, both getting in and getting out. I almost want to say that you shouldn't even bother trading underlyings bigger than a 10 cent bid/ask spread with a small account.
Get an idea of the timeframe you're interested in holding before putting anything on. Have a plan for entering and exiting everything that goes beyond "I'll take this trade off at 50%". You can use TA, you can use a news catalyst, a binary event, just have something. Countless sources out there talk about trading a plan. It doesn't have to be the perfect plan, it just has to be "a" plan.
Undefined risk trades in tiny accounts need hard stops. Yes, some of the studies say that you'll do better without having fixed stop loss rules (50% of max loss, 100% of max loss) -- but what the studies don't say is the effect that it will have on you, mentally. I got pretty bent out of shape over how badly EWZ and EWW went against me -- much more than I expected. It made no sense, as I've lost way more on the turn of a card in .5 seconds and been unfazed. I was unprepared for the mental toll that it took waking up day after day, watching positions move further and further against me. Great time to be short calls during the mother of all rallies.
My initial plan for undefined risk trades in my account was that I would only do them in ETFs. Logic being that I'm just not going to wake up to an accounting scandal or a buyout and take a $1k loss on the chin. I later expanded my range into lower priced underlyings like BBBY, TLRY, and yes, AAL. But these ETFs can and do move (I learned the hard way) and can soak up a surprising amount of BP. It might be better to have 5 iron condors taking up $1000 of BP @ 200 each instead of 2 strangles @ 500 each.
My new questions :
My big wins felt like I simply leaned on my TA background or got lucky. My big losses, I sure felt like I earned those, through mistakes I've definitely since identified. The stuff in the middle, I'm just not sure. I'm up money, but it feels like I'm just spinning my wheels. My win rate is good, but I still struggle with expectations about how quickly a trade should progress. What is the next step of the process for a newer options trader? I've read some stuff on narrower spreads + more contracts vs. wider spreads and fewer contracts. Is there a number where I should just keep doing what I'm doing until I reach a specific # of occurrences? Should I even think about branching out into different strategies yet (ratio spreads, jade lizards, etc) or continue to work on these basics?
I still feel like I am super weak in delta management. In some cases I feel like I've taken a loss simply because I didn't know what the proper management techniques were. I understand the concept of rolling out in time for a credit, but I just don't think it's in my nature to hold trades for longer than a month, and even that is hard for me. At what delta is it appropriate to start thinking about hedging?
Every time I put on a credit spread for a 2-3 day move and am directionally correct, I often wish that I had just bought a naked option. I've caught several big moves this way in things like AAPL; most recently I bought the FB dip to the 50 day MA around 215 and took it off today at 225 (which was always my plan) -- it leads me to wonder if my expectations for credit spreads are completely out of line. I can't lie, it feels bad to catch a 10 point move and only make $40, haha. What is the ideal timeframe for a credit spread to be left on? Is it better to just buy premium with a stop loss and have a more profitable risk/reward equation for situations like the above where the only intent is to hold for a couple days?
Here's a random question -- other than when the BPR hit is too much (ie names over $50) for undefined risk, would you rather hold 1) a strangle for 10-14 days or 2) an iron condor for 25-30 days? So far my criteria for IC vs strangle has largely been driven by the risk profile and BPR and not so much profit potential in X number of days. If you're collecting the standard 1/3rd on the IC and taking the trade off at 50% (if you're lucky) , it seems like it takes about a month to get there, most of the time.
That's enough of this wall of text for now. If you made it this far, I salute you, because this shit was even longer than my last post.
SNAP preview, expected move and spread strike selection
Snap (SNAP) reports q2 earnings after the close Tuesday (~4:10pm)
Options are pricing an expected move of 12% by this Friday. That is the bulk of the move expected over the next month, which is about 15%.
Snap closed higher by about 36% in the day following its most recent earnings (in April)
Snap has beaten consensus estimates 7 out of the last 8 times.
https://preview.redd.it/d5e4r4ho28c51.png?width=583&format=png&auto=webp&s=9790a1e378ed329c5d66910d814093260814f70d Neutral - The first thing to look at is a neutral position, selling to both the bulls and the bears. Here are two neutral trades setting breakevens at or near the expected move. First selling the +21.5/-22.5/-28/+29 Iron Condor(condor chart) In this case the risk reward is $56 to make $44. If the stock closes anywhere between 22.5 and 28 on Friday it is a max gain. Any close beyond 21.5 or 29 and a max loss. The breakeven is 22.06 on the downside and 28.44 on the upside. That trade establishes a range of max profit, for those targeting no move at all, with the stock remaining at 25 selling an Iron Butterfly has max profit at the 25 level with profits trailing off towards the expected move and losses beyond: Fly chart Both of these trades are binary, isolating this week and what is likely to be a mostly one day move tomorrow. Bullish - For those thinking directionally the expected move can be used to help determine strike selection. Here's a bullish price target looking out a bit further in time, to August expiration: Trade comparison. In this case both the August long call spread (+25/-29) and the August short put spread (-25/+21) take advantage of multi leg strike selection based on the expected move. The short put spread is "selling to the bears" and is profitable from 22.57 and higher with a max gain if the stock is above 25 on August expiration. The long call spread has a higher breakeven, but by selling the 29 call at a high upside volatility, is much cheaper than an outright 25 call. Bearish - The same is true for a bearish target in line with the expected move but the short call spread is at a slight disadvantage due to having to buy the upside call at a similar or higher IV than the at the money call sale: Trade comparison Full post here.
Hi everyone, this is my first ever post here. I run a little website called The Thought Experiment where I talk about various issues, some of them Singapore related. And one of my main interests is Singaporean politics. With the GE2020 election results, I thought I should pen down my take on what us as the electorate were trying to say. If you like what I wrote, I also wrote another article on the state of play for GE2020 during the campaigning period, as well as 2 other articles related to GE2015 back when it was taking place. If you don't like what I wrote, that's ok! I think the beauty of freedom of expression is that everyone is entitled to their opinion. I'm always happy to get feedback, because I do think that more public discourse about our local politics helps us to be more politically aware as a whole. Just thought I'll share my article here to see what you guys make of it :D Article Starts Here: During the campaigning period, both sides sought to portray an extreme scenario of what would happen if voters did not vote for them. The Peoples’ Action Party (PAP) warned that Singaporeans that their political opponents “might eventually replace the government after July 10”. Meanwhile, the Worker’s Party (WP) stated that “there was a real risk of a wipeout of elected opposition MPs at the July 10 polls”. Today is July 11th. As we all know, neither of these scenarios came to pass. The PAP comfortably retained its super-majority in Parliament, winning 83 out of 93 elected MP seats. But just as in GE2011, another Group Representation Constituency (GRC) has fallen to the WP. In addition, the PAP saw its vote share drop drastically, down almost 9% to 61.2% from 69.9% in GE2015. Singapore’s electorate is unique in that a significant proportion is comprised of swing voters: Voters who don’t hold any blind allegiance to any political party, but vote based on a variety of factors both micro and macro. The above extreme scenarios were clearly targeted at these swing voters. Well, the swing voters have made their choice, their roar sending 4 more elected opposition MPs into Parliament. This article aims to unpack that roar and what it means for the state of Singaporean politics going forward. 1. The PAP is still the preferred party to form Singapore’s Government Yes, this may come across as blindingly obvious, but it still needs to be said. The swing voter is by its very definition, liable to changes of opinion. And a large factor that determines how a swing voter votes is their perception of how their fellow swing voters are voting. If swing voters perceive that most swing voters are leaning towards voting for the opposition, they might feel compelled to vote for the incumbent. And if the reverse is true, swing voters might feel the need to shore up opposition support. Why is this so? This is because the swing voter is trying to push the vote result into a sweet spot – one that lies between the two extreme scenarios espoused by either side. They don’t want the PAP to sweep all 93 seats in a ‘white tsunami’. Neither do they want the opposition to claim so much territory that the PAP is too weak to form the Government on its own. But because each swing voter only has a binary choice: either they vote for one side or the other (I’m ignoring the third option where they simply spoil their vote), they can’t very well say “I want to vote 0.6 for the PAP and 0.4 for the Opposition with my vote”. And so we can expect the swing voter bloc to continue being a source of uncertainty for both sides in future elections, as long as swing voters are still convinced that the PAP should be the Government. 2. Voters no longer believe that the PAP needs a ‘strong mandate’ to govern. They also don’t buy into the NCMP scheme. Throughout the campaign period, the PAP repeatedly exhorted voters to vote for them alone. Granted, they couldn’t very well give any ground to the opposition without a fight. And therefore there was an attempt to equate voting for the PAP as voting for Singapore’s best interests. However, the main message that voters got was this: PAP will only be able to steer Singapore out of the Covid-19 pandemic if it has a strong mandate from the people. What is a strong mandate, you may ask? While no PAP candidate publicly confirmed it, their incessant harping on the Non-Constituency Member of Parliament (NCMP) scheme as the PAP’s win-win solution for having the PAP in power and a largely de-fanged opposition presence in parliament shows that the PAP truly wanted a parliament where it held every single seat. Clearly, the electorate has different ideas, handing Sengkang GRC to the WP and slashing the PAP’s margins in previous strongholds such as West Coast, Choa Chu Kang and Tanjong Pagar by double digit percentages. There is no doubt from the results that swing voters are convinced that a PAP supermajority is not good for Singapore. They are no longer convinced that to vote for the opposition is a vote against Singapore. They have realized, as members of a maturing democracy surely must, that one can vote for the opposition, yet still be pro-Singapore. 3. Social Media and the Internet are rewriting the electorate’s perception. In the past, there was no way to have an easily accessible record of historical events. With the only information source available being biased mainstream media, Singaporeans could only rely on that to fill in the gaps in their memories. Therefore, Operation Coldstore became a myth of the past, and Chee Soon Juan became a crackpot in the eyes of the people, someone who should never be allowed into Parliament. Fast forward to today. Chee won 45.2% of the votes in Bukit Batok’s Single Member Constituency (SMC). His party-mate, Dr. Paul Tambyah did even better, winning 46.26% of the votes in Bukit Panjang SMC. For someone previously seen as unfit for public office, this is an extremely good result. Chee has been running for elections in Singapore for a long time, and only now is there a significant change in the way he is perceived (and supported) by the electorate. Why? Because of social media and the internet, two things which the PAP does not have absolute control over. With the ability to conduct interviews with social media personalities as well as upload party videos on Youtube, he has been able to display a side of himself to people that the PAP did not want them to see: someone who is merely human just like them, but who is standing up for what he believes in. 4. Reserved Election Shenanigans and Tan Cheng Block: The electorate has not forgotten. Tan Cheng Bock almost became our President in 2011. There are many who say that if Tan Kin Lian and Tan Jee Say had not run, Tony Tan would not have been elected. In March 2016, Tan Cheng Bock publicly declared his interest to run for the next Presidential Election that would be held in 2017. The close result of 2011 and Tan Cheng Bock’s imminent candidacy made the upcoming Presidential Election one that was eagerly anticipated. That is, until the PAP shut down his bid for the presidency just a few months later in September 2016, using its supermajority in Parliament to pass a “reserved election” in which only members of a particular race could take part. Under the new rules that they had drawn up for themselves, it was decreed that only Malays could take part. And not just any Malay. The candidate had to either be a senior executive managing a firm that had S$500 million in shareholders’ equity, or be the Speaker of Parliament or a similarly high post in the public sector (the exact criteria are a bit more in-depth than this, but this is the gist of it. You can find the full criteria here). And who was the Speaker of Parliament at the time? Mdm Halimah, who was conveniently of the right race (Although there was some hooha about her actually being Indian). With the extremely strict private sector criteria and the PAP being able to effectively control who the public sector candidate was, it came as no surprise that Mdm Halimah was declared the only eligible candidate on Nomination Day. A day later, she was Singapore’s President. And all without a single vote cast by any Singaporean. Of course, the PAP denied that this was a move specifically aimed at blocking Tan Cheng Bock’s bid for the presidency. Chan Chun Sing, Singapore’s current Minister of Trade and Industry, stated in 2017 that the Government was prepared to pay the political price over making these changes to the Constitution. We can clearly see from the GE2020 results that a price was indeed paid. A loss of almost 9% of vote share is very significant, although a combination of the first-past-the-post rule and the GRC system ensured that the PAP still won 89.2% of the seats in Parliament despite only garnering 61.2% of the votes. On the whole, it’s naught but a scratch to the PAP’s overwhelming dominance in Parliament. The PAP still retains its supermajority and can make changes to the Constitution anytime that it likes. But the swing voters have sent a clear signal that they have not been persuaded by the PAP’s rationale. 5. Swing Voters do not want Racial Politics. In 2019, Heng Swee Keat, Singapore’s Deputy Prime Minister and the man who is next in line to be Prime Minister (PM) commented that Singapore was not ready to have a non-Chinese PM. He further added that race is an issue that always arises at election-time in Singapore. Let us now consider the GE2015 results. Tharman Shanmugaratnam, Singapore’s Senior Minister and someone whom many have expressed keenness to be Singapore’s next PM, obtained 79.28% of the vote share in Jurong GRC. This was above even the current Prime Minister Lee Hsien Loong, who scored 78.63% in Ang Mo Kio GRC. Tharman’s score was the highest in the entire election. And now let us consider the GE2020 results. Tharman scored 74.62% in Jurong, again the highest scorer of the entire election, while Hsien Loong scored 71.91%. So Tharman beat the current PM again, and by an even bigger margin than the last time. Furthermore, Swee Keat, who made the infamous comments above, scored just 53.41% in East Coast. Yes, I know I’m ignoring a lot of other factors that influenced these results. But don’t these results show conclusively that Heng’s comments were wrong? We have an Indian leading both the current and future PM in both elections, but yet PAP still feels the need to say that Singapore “hasn’t arrived” at a stage where we can vote without race in mind. In fact, this was the same rationale that supposedly led to the reserved presidency as mentioned in my earlier point. The swing voters have spoken, and it is exceedingly clear to me that the electorate does not care what our highest office-holders are in terms of race, whether it be the PM or the President. Our Singapore pledge firmly states “regardless of race”, and I think the results have shown that we as a people have taken it to heart. But has the PAP? 6. Voters will not be so easily manipulated. On one hand, Singaporeans were exhorted to stay home during the Covid-19 pandemic. Contact tracing became mandatory, and groups of more than 5 are prohibited. But on the other hand, we are also told that it’s absolutely necessary to hold an election during this same period, for Singaporeans to wait in long lines and in close proximity to each other as we congregate to cast our vote, all because the PAP needs a strong mandate. On one hand, Heng Swee Keat lambasted the Worker’s Party, claiming that it was “playing games with voters” over their refusal to confirm if they would accept NCMP seats. But on the other hand, Heng Swee Keat was moved to the East Coast GRC at the eleventh hour in a surprise move to secure the constituency. (As mentioned above, he was aptly rewarded for this with a razor-thin margin of just 53.41% of the votes.) On one hand, Masagos Zulkifli, PAP Vice-Chairman stated that “candidates should not be defined by a single moment in time or in their career, but judged instead by their growth throughout their life”. He said this in defense of Ivan Lim, who appears to be the very first candidate in Singaporean politics to have been pushed into retracting his candidacy by the power of non-mainstream media. But on the other hand, the PAP called on the WP to make clear its stand on Raeesah Khan, a WP candidate who ran (and won) in Sengkang GRC for this election, stating that the Police investigation into Raeesah’s comments made on social media was “a serious matter which goes to the fundamental principles on which our country has been built”. On one hand, Chan Chun Sing stated in 2015, referring to SingFirst’s policies about giving allowances to the young and the elderly, “Some of them promised you $300 per month. I say, please don’t insult my residents. You think…. they are here to be bribed?” On the other hand, the PAP Government has just given out several handouts under its many budgets to help Singaporeans cope with the Covid-19 situation. [To be clear, I totally approve of these handouts. What I don’t approve is that the PAP felt the need to lambast similar policies as bribery in the past. Comparing a policy with a crime is a political low blow in my book.] I could go on, but I think I’ve made my point. And so did the electorate in this election, putting their vote where it counted to show their disdain for the heavy-handedness and double standards that the PAP has displayed for this election. Conclusion I don’t say the above to put down the PAP. The PAP would have you believe that to not support them is equivalent to not wanting what’s best for Singapore. This is a false dichotomy that must be stamped out, and I am glad to see our swing voters taking a real stand with this election. No, I say the above as a harsh but ultimately supportive letter to the PAP. As everyone can see from the results, we all still firmly believe that the PAP should be the Government. We still have faith that PAP has the leadership to take us forward and out of the Covid-19 crisis. But we also want to send the PAP a strong signal with this vote, to bring them down from their ivory towers and down to the ground. Enough with the double standards. Enough with the heavy-handedness. Singaporeans have clearly stated their desire for a more mature democracy, and that means more alternative voices in Parliament. The PAP needs to stop acting as the father who knows it all, and to start acting as the bigger brother who can work hand in hand with his alternative younger brother towards what’s best for the entire family: Singapore. There is a real chance that the PAP will not listen, though. As Lee Hsien Loong admitted in a rally in 2006, “if there are 10, 20… opposition members in Parliament… I have to spent my time thinking what is the right way to fix them”. Now, the PAP has POFMA at its disposal. It still has the supermajority in Parliament, making them able to change any law in Singapore, even the Constitution at will. We have already seen them put these tools to use for its own benefit. Let us see if the PAP will continue as it has always done, or will it take this opportunity to change itself for the better. Whatever the case, we will be watching, and we will be waiting to make our roar heard once again five years down the road. Majulah Singapura! Article Ends Here.

Selling your Covered Call - Thoughts on How to Select Your Strike and Expiration
Congratulations! You are a bag holder of company XYZ which was thought to be the best penny stock ever. Instead of feeling sorry, you consider selling covered calls to help reduce your cost basis - and eventually get out of your bags with minimal loss or even a profit! First - let's review the call option contract. The holder of the call option contract has the right but not the obligation to purchase 100 shares of XYZ at the strike price per share. This contract has an expiration date. We assume American style option contracts which means that the option can be exercised at any point prior to expiration. Thus, there are three parameters to the option contract - the strike price, the expiration date and the premium - which represents the price per share of the contract. The holder of the call option contract is the person that buys the option. The writer of the contract is the seller. The buyer (or holder) pays the premium. The seller (or writer) collects the premium. As an XYZ bag holder, the covered call may help. By writing a call contract against your XYZ shares, you can collect premium to reduce your investment cost in XYZ - reducing your average cost per share. For every 100 shares of XYZ, you can write 1 call contract. Notice that that by selling the contract, you do not control if the call is exercised - only the holder of the contract can exercise it. There are several online descriptions about the covered call strategy. Here is an example that might be useful to review Covered Call Description The general guidance is to select the call strike at the price in which you would be happy selling your shares. However, the context of most online resources on the covered call strategy assume that you either just purchased the shares at market value or your average cost is below the market price. In the case as a bag holder, your average cost is most likely over - if not significantly over - the current market price. This situation simply means that you have a little work to reduce your average before you are ready to have your bags called away. For example, you would not want to have your strike set at $2.50 when your average is above that value as this would guarantee a net loss. (However, if you are simply trying to rid your bags and your average is slightly above the strike, then you might consider it as the strike price). One more abstract concept before getting to what you want to know. The following link shows the Profit/Loss Diagram for Covered Call Conceptually, the blue line shows the profit/loss value of your long stock position. The line crosses the x-axis at your average cost, i.e the break-even point for the long stock position. The green/red hockey stick is the profit (green) or loss (red) of the covered call position (100 long stock + 1 short call option). The profit has a maximum value at the strike price. This plateau is due to the fact that you only receive the agreed upon strike price per share when the call option is exercised. Below the strike, the profit decreases along the unit slope line until the value becomes negative. It is a misnomer to say that the covered call is at 'loss' since it is really the long stock that has decreased in value - but it is not loss (yet). Note that the break-even point marked in the plot is simply the reduced averaged cost from the collected premium selling the covered call. As a bag holder, it will be a two-stage process: (1) reduce the average cost (2) get rid of bags. Okay let's talk selecting strike and expiration. You must jointly select these two parameters. Far OTM strikes will collect less premium where the premium will increase as you move the strike closer to the share price. Shorter DTE will also collect less premium where the premium will increase as you increase the DTE. It is easier to describe stage 2 "get rid of bags" first. Let us pretend that our hypothetical bag of 100 XYZ shares cost us $5.15/share. The current XYZ market price is $3/share - our hole is $2.15/share that we need to dig out. Finally, assume the following option chain (all hypothetical):
Purely made up the numbers, but the table illustrates the notional behavior of an option chain. The option value (premium) is the intrinsic value plus the time value. Only the $2.5 strike has intrinsic value since the share price is $3 (which is greater than $2.5). Notice that intrinsic value cannot be negative. The rest of the premium is the time value of the option which is essentially the monetary bet associated with the probability that the share price will exceed the strike at expiration. According to the table, we could collect the most premium by selling the 110 DTE $2.5 call for $0.95. However, there is a couple problems with that option contract. We are sitting with bags at $5.15/share and receiving $0.95 will only reduce our average to $4.20/share. On expiration, if still above $2.5, then we are assigned, shares called away and we receive $2.50/share or a loss of $170 - not good. Well, then how about the $5 strike at 110 DTE for $0.50? This reduces us to $4.65/share which is under the $5 strike so we would make a profit of $35! This is true - however 110 days is a long time to make $35. You might say that is fine you just want to get the bags gone don't care. Well maybe consider a shorter DTE - even the 20 DTE or 50 DTE would collect premium that reduces your average below $5. This would allow you to react to any stock movement that occurs in the near-term. Consider person A sells the 110 DTE $5 call and person B sells the 50 DTE $5 call. Suppose that the XYZ stock increases to $4.95/share in 50 days then goes to $8 in the next 30 days then drops to $3 after another 30 days. This timeline goes 110 days and person A had to watch the price go up and fall back to the same spot with XYZ stock at $3/share. Granted the premium collected reduced the average but stilling hold the bags. Person B on the other hand has the call expire worthless when XYZ is at $4.95/share. A decision can be made - sell immediately, sell another $5 call or sell a $7.5 call. Suppose the $7.5 call is sold with 30 DTE collecting some premium, then - jackpot - the shares are called away when XYZ is trading at $8/share! Of course, no one can predict the future, but the shorter DTE enables more decision points. The takeaway for the second step in the 2-stage approach is that you need to select your profit target to help guide your strike selection. In this example, are you happy with the XYZ shares called away at $5/share or do you want $7.5/share? What is your opinion on the stock price trajectory? When do you foresee decision points? This will help determine the strike/expiration that matches your thoughts. Note: studies have shown that actively managing your position results in better performance than simply waiting for expiration, so you can adjust the position if your assessment on the movement is incorrect. Let's circle back to the first step "reduce the average cost". What if your average cost of your 100 shares of XYZ is $8/share? Clearly, all of the strikes in our example option chain above is "bad" to a certain extent since we would stand to lose a lot of money if the option contract is exercised. However, by describing the second step, we know the objective for this first step is to reduce our average such that we can profit from the strikes. How do we achieve this objective? It is somewhat the same process as previously described, but you need to do your homework a little more diligently. What is your forecast on the stock movement? Since $7.5 is the closest strike to your average, when do you expect XYZ to rise from $3/share to $7.5/share? Without PR, you might say never. With some PR then maybe 50/50 chance - if so, then what is the outlook for PR? What do you think the chances of going to $5/share where you could collect more premium? Suppose that a few XYZ bag holders (all with a $8/share cost) discuss there outlook of the XYZ stock price in the next 120 days:
Person A does not seem to think much price movement will occur. This person might sell the $5 call with either 20 DTE or 50 DTE. Then upon expiration, sell another $5 call for another 20-50 DTE. Person A could keep repeating this until the average is reduced enough to move onto step-2. Of course, this approach is risky if the Person A price forecast is incorrect and the stock price goes up - which might result in assignment too soon. Person B appears to be the most bullish of the group. This person might sell the $5 call with 20 DTE then upon expiration sell the $7.5 call. After expiration, Person B might decide to leave the shares uncovered because her homework says XYZ is going to explode and she wants to capture those gains! Person C believes that there will be a step increase in 10 days maybe due to major PR event. This person will not have the chance to reduce the average in time to sell quickly, so first he sells a $7.5 call with 20 DTE to chip at the average. At expiration, Person C would continue to sell $7.5 calls until the average at the point where he can move onto the "get rid of bags" step. In all causes, each person must form an opinion on the XYZ price movement. Of course, the prediction will be wrong at some level (otherwise they wouldn't be bag holders!). The takeaway for the first step in the 2-stage approach is that you need to do your homework to better forecast the price movement to identify the correct strikes to bring down your average. The quality of the homework and the risk that you are willing to take will dedicate the speed at which you can reduce your average. Note that if you are unfortunate to have an extremely high average per share, then you might need to consider doing the good old buy-more-shares-to-average-down. This will be the fastest way to reduce your average. If you cannot invest more money, then the approach above will still work, but it will require much more patience. Remember there is no free lunch! Advanced note: there is another method to reduce your (high) average per share - selling cash secured puts. It is the "put version" of a cover call. Suppose that you sell a XYZ $2.5 put contract for $0.50 with 60 DTE. You collect $50 from the premium of the contract. This money is immediately in your bank and reduces your investment cost. But what did you sell? If XYZ is trading below $2.50, then you will be assigned 100 shares of XYZ at $2.50/share or $250. You own more shares, but at a price which will reduce your average further. Being cash secured, your brokerage will reserve $250 from your account when you sell the contract. In essence, you reduce your buying power by $250 and conditionally purchase the shares - you do not have them until assignment. If XYZ is greater than the strike at expiration, then your broker gives back $250 cash / buying power and you keep the premium. Early assignment - one concern is the chance of early assignment. The American style option contract allows the holder the opportunity to exercise the contract at any time prior to expiration. Early assignment almost never occurs. There are special cases that typically deal with dividends but most penny stocks are not in the position to hand out dividends. Aside from that, the holder would be throwing away option time value by early exercise. It possibly can handle - probably won't - it actually would be a benefit when selling covered calls as you would receive your profit more quickly! This post has probably gone too long! I will stop and let's discuss this matter. I will add follow-on material with some of the following topics which factors into this discussion:
Effect of earnings / PR / binary events on the option contract - this reaction may be different than the underlying stock reaction to the event
The Black-Scholes option pricing model allows one to understand how the premium will change - note that "all models are incorrect, but some are useful"
The "Greeks" give you a sense about how prices change when the stock price change - Meet the Greeks video
Position Management - when to adjust, close, or roll
Legging position into strangles/straddles - more advanced position with higher risk / higher reward
Open to other suggestions. I'm sure there are some typos and unclear statements - I will edit as needed! \I'm not a financial advisor. Simply helping to 'coach' people through the process.

Everything You Always Wanted To Know About Swaps* (*But Were Afraid To Ask)
Hello, dummies It's your old pal, Fuzzy. As I'm sure you've all noticed, a lot of the stuff that gets posted here is - to put it delicately - fucking ridiculous. More backwards-ass shit gets posted to wallstreetbets than you'd see on a Westboro Baptist community message board. I mean, I had a look at the daily thread yesterday and..... yeesh. I know, I know. We all make like the divine Laura Dern circa 1992 on the daily and stick our hands deep into this steaming heap of shit to find the nuggets of valuable and/or hilarious information within (thanks for reading, BTW). I agree. I love it just the way it is too. That's what makes WSB great. What I'm getting at is that a lot of the stuff that gets posted here - notwithstanding it being funny or interesting - is just... wrong. Like, fucking your cousin wrong. And to be clear, I mean the fucking your *first* cousin kinda wrong, before my Southerners in the back get all het up (simmer down, Billy Ray - I know Mabel's twice removed on your grand-sister's side). Truly, I try to let it slide. Idomybit to try and put you on the right path. Most of the time, I sleep easy no matter how badly I've seen someone explain what a bank liquidity crisis is. But out of all of those tens of thousands of misguided, autistic attempts at understanding the world of high finance, one thing gets so consistently - so *emphatically* - fucked up and misunderstood by you retards that last night I felt obligated at the end of a long work day to pull together this edition of Finance with Fuzzy just for you. It's so serious I'm not even going to make a u/pokimane gag. Have you guessed what it is yet? Here's a clue. It's in the title of the post. That's right, friends. Today in the neighborhood we're going to talk all about hedging in financial markets - spots, swaps, collars, forwards, CDS, synthetic CDOs, all that fun shit. Don't worry; I'm going to explain what all the scary words mean and how they impact your OTM RH positions along the way. We're going to break it down like this. (1) "What's a hedge, Fuzzy?" (2) Common Hedging Strategies and (3) All About ISDAs and Credit Default Swaps. Before we begin. For the nerds and JV traders in the back (and anyone else who needs to hear this up front) - I am simplifying these descriptions for the purposes of this post. I am also obviously not going to try and cover every exotic form of hedge under the sun or give a detailed summation of what caused the financial crisis. If you are interested in something specific ask a question, but don't try and impress me with your Investopedia skills or technical points I didn't cover; I will just be forced to flex my years of IRL experience on you in the comments and you'll look like a big dummy. TL;DR? Fuck you. There is no TL;DR. You've come this far already. What's a few more paragraphs? Put down the Cheetos and try to concentrate for the next 5-7 minutes. You'll learn something, and I promise I'll be gentle. Ready? Let's get started. 1.The Tao of Risk: Hedging as a Way of Life The simplest way to characterize what a hedge 'is' is to imagine every action having a binary outcome. One is bad, one is good. Red lines, green lines; uppie, downie. With me so far? Good. A 'hedge' is simply the employment of a strategy to mitigate the effect of your action having the wrong binary outcome. You wanted X, but you got Z! Frowny face. A hedge strategy introduces a third outcome. If you hedged against the possibility of Z happening, then you can wind up with Y instead. Not as good as X, but not as bad as Z. The technical definition I like to give my idiot juniors is as follows: Utilization of a defensive strategy to mitigate risk, at a fraction of the cost to capital of the risk itself. Congratulations. You just finished Hedging 101. "But Fuzzy, that's easy! I just sold a naked call against my 95% OTM put! I'm adequately hedged!". Spoiler alert: you're not (although good work on executing a collar, which I describe below). What I'm talking about here is what would be referred to as a 'perfect hedge'; a binary outcome where downside is totally mitigated by a risk management strategy. That's not how it works IRL. Pay attention; this is the tricky part. You can't take a single position and conclude that you're adequately hedged because risks are fluid, not static. So you need to constantly adjust your position in order to maximize the value of the hedge and insure your position. You also need to consider exposure to more than one category of risk. There are micro (specific exposure) risks, and macro (trend exposure) risks, and both need to factor into the hedge calculus. That's why, in the real world, the value of hedging depends entirely on the design of the hedging strategy itself. Here, when we say "value" of the hedge, we're not talking about cash money - we're talking about the intrinsic value of the hedge relative to the the risk profile of your underlying exposure. To achieve this, people hedge dynamically. In wallstreetbets terms, this means that as the value of your position changes, you need to change your hedges too. The idea is to efficiently and continuously distribute and rebalance risk across different states and periods, taking value from states in which the marginal cost of the hedge is low and putting it back into states where marginal cost of the hedge is high, until the shadow value of your underlying exposure is equalized across your positions. The punchline, I guess, is that one static position is a hedge in the same way that the finger paintings you make for your wife's boyfriend are art - it's technically correct, but you're only playing yourself by believing it. Anyway. Obviously doing this as a small potatoes trader is hard but it's worth taking into account. Enough basic shit. So how does this work in markets? 2. A Hedging Taxonomy The best place to start here is a practical question. What does a business need to hedge against? Think about the specific risk that an individual business faces. These are legion, so I'm just going to list a few of the key ones that apply to most corporates. (1) You have commodity risk for the shit you buy or the shit you use. (2) You have currency risk for the money you borrow. (3) You have rate risk on the debt you carry. (4) You have offtake risk for the shit you sell. Complicated, right? To help address the many and varied ways that shit can go wrong in a sophisticated market, smart operators like yours truly have devised a whole bundle of different instruments which can help you manage the risk. I might write about some of the more complicated ones in a later post if people are interested (CDO/CLOs, strip/stack hedges and bond swaps with option toggles come to mind) but let's stick to the basics for now. (i) Swaps A swap is one of the most common forms of hedge instrument, and they're used by pretty much everyone that can afford them. The language is complicated but the concept isn't, so pay attention and you'll be fine. This is the most important part of this section so it'll be the longest one. Swaps are derivative contracts with two counterparties (before you ask, you can't trade 'em on an exchange - they're OTC instruments only). They're used to exchange one cash flow for another cash flow of equal expected value; doing this allows you to take speculative positions on certain financial prices or to alter the cash flows of existing assets or liabilities within a business. "Wait, Fuzz; slow down! What do you mean sets of cash flows?". Fear not, little autist. Ol' Fuzz has you covered. The cash flows I'm talking about are referred to in swap-land as 'legs'. One leg is fixed - a set payment that's the same every time it gets paid - and the other is variable - it fluctuates (typically indexed off the price of the underlying risk that you are speculating on / protecting against). You set it up at the start so that they're notionally equal and the two legs net off; so at open, the swap is a zero NPV instrument. Here's where the fun starts. If the price that you based the variable leg of the swap on changes, the value of the swap will shift; the party on the wrong side of the move ponies up via the variable payment. It's a zero sum game. I'll give you an example using the most vanilla swap around; an interest rate trade. Here's how it works. You borrow money from a bank, and they charge you a rate of interest. You lock the rate up front, because you're smart like that. But then - quelle surprise! - the rate gets better after you borrow. Now you're bagholding to the tune of, I don't know, 5 bps. Doesn't sound like much but on a billion dollar loan that's a lot of money (a classic example of the kind of 'small, deep hole' that's terrible for profits). Now, if you had a swap contract on the rate before you entered the trade, you're set; if the rate goes down, you get a payment under the swap. If it goes up, whatever payment you're making to the bank is netted off by the fact that you're borrowing at a sub-market rate. Win-win! Or, at least, Lose Less / Lose Less. That's the name of the game in hedging. There are many different kinds of swaps, some of which are pretty exotic; but they're all different variations on the same theme. If your business has exposure to something which fluctuates in price, you trade swaps to hedge against the fluctuation. The valuation of swaps is also super interesting but I guarantee you that 99% of you won't understand it so I'm not going to try and explain it here although I encourage you to google it if you're interested. Because they're OTC, none of them are filed publicly. Someeeeeetimes you see an ISDA (dsicussed below) but the confirms themselves (the individual swaps) are not filed. You can usually read about the hedging strategy in a 10-K, though. For what it's worth, most modern credit agreements ban speculative hedging. Top tip: This is occasionally something worth checking in credit agreements when you invest in businesses that are debt issuers - being able to do this increases the risk profile significantly and is particularly important in times of economic volatility (ctrl+f "non-speculative" in the credit agreement to be sure). (ii) Forwards A forward is a contract made today for the future delivery of an asset at a pre-agreed price. That's it. "But Fuzzy! That sounds just like a futures contract!". I know. Confusing, right? Just like a futures trade, forwards are generally used in commodity or forex land to protect against price fluctuations. The differences between forwards and futures are small but significant. I'm not going to go into super boring detail because I don't think many of you are commodities traders but it is still an important thing to understand even if you're just an RH jockey, so stick with me. Just like swaps, forwards are OTC contracts - they're not publicly traded. This is distinct from futures, which are traded on exchanges (see The Ballad Of Big Dick Vick for some more color on this). In a forward, no money changes hands until the maturity date of the contract when delivery and receipt are carried out; price and quantity are locked in from day 1. As you now know having read about BDV, futures are marked to market daily, and normally people close them out with synthetic settlement using an inverse position. They're also liquid, and that makes them easier to unwind or close out in case shit goes sideways. People use forwards when they absolutely have to get rid of the thing they made (or take delivery of the thing they need). If you're a miner, or a farmer, you use this shit to make sure that at the end of the production cycle, you can get rid of the shit you made (and you won't get fucked by someone taking cash settlement over delivery). If you're a buyer, you use them to guarantee that you'll get whatever the shit is that you'll need at a price agreed in advance. Because they're OTC, you can also exactly tailor them to the requirements of your particular circumstances. These contracts are incredibly byzantine (and there are even crazier synthetic forwards you can see in money markets for the true degenerate fund managers). In my experience, only Texan oilfield magnates, commodities traders, and the weirdo forex crowd fuck with them. I (i) do not own a 10 gallon hat or a novelty size belt buckle (ii) do not wake up in the middle of the night freaking out about the price of pork fat and (iii) love greenbacks too much to care about other countries' monopoly money, so I don't fuck with them. (iii) Collars No, not the kind your wife is encouraging you to wear try out to 'spice things up' in the bedroom during quarantine. Collars are actually the hedging strategy most applicable to WSB. Collars deal with options! Hooray! To execute a basic collar (also called a wrapper by tea-drinking Brits and people from the Antipodes), you buy an out of the money put while simultaneously writing a covered call on the same equity. The put protects your position against price drops and writing the call produces income that offsets the put premium. Doing this limits your tendies (you can only profit up to the strike price of the call) but also writes down your risk. If you screen large volume trades with a VOL/OI of more than 3 or 4x (and they're not bullshit biotech stocks), you can sometimes see these being constructed in real time as hedge funds protect themselves on their shorts. (3) All About ISDAs, CDS and Synthetic CDOs You may have heard about the mythical ISDA. Much like an indenture (discussed in my post on $F), it's a magic legal machine that lets you build swaps via trade confirms with a willing counterparty. They are very complicated legal documents and you need to be a true expert to fuck with them. Fortunately, I am, so I do. They're made of two parts; a Master (which is a form agreement that's always the same) and a Schedule (which amends the Master to include your specific terms). They are also the engine behind just about every major credit crunch of the last 10+ years. First - a brief explainer. An ISDA is a not in and of itself a hedge - it's an umbrella contract that governs the terms of your swaps, which you use to construct your hedge position. You can trade commodities, forex, rates, whatever, all under the same ISDA. Let me explain. Remember when we talked about swaps? Right. So. You can trade swaps on just about anything. In the late 90s and early 2000s, people had the smart idea of using other people's debt and or credit ratings as the variable leg of swap documentation. These are called credit default swaps. I was actually starting out at a bank during this time and, I gotta tell you, the only thing I can compare people's enthusiasm for this shit to was that moment in your early teens when you discover jerking off. Except, unlike your bathroom bound shame sessions to Mom's Sears catalogue, every single person you know felt that way too; and they're all doing it at once. It was a fiscal circlejerk of epic proportions, and the financial crisis was the inevitable bukkake finish. WSB autism is absolutely no comparison for the enthusiasm people had during this time for lighting each other's money on fire. Here's how it works. You pick a company. Any company. Maybe even your own! And then you write a swap. In the swap, you define "Credit Event" with respect to that company's debt as the variable leg . And you write in... whatever you want. A ratings downgrade, default under the docs, failure to meet a leverage ratio or FCCR for a certain testing period... whatever. Now, this started out as a hedge position, just like we discussed above. The purest of intentions, of course. But then people realized - if bad shit happens, you make money. And banks... don't like calling in loans or forcing bankruptcies. Can you smell what the moral hazard is cooking? Enter synthetic CDOs. CDOs are basically pools of asset backed securities that invest in debt (loans or bonds). They've been around for a minute but they got famous in the 2000s because a shitload of them containing subprime mortgage debt went belly up in 2008. This got a lot of publicity because a lot of sad looking rednecks got foreclosed on and were interviewed on CNBC. "OH!", the people cried. "Look at those big bad bankers buying up subprime loans! They caused this!". Wrong answer, America. The debt wasn't the problem. What a lot of people don't realize is that the real meat of the problem was not in regular way CDOs investing in bundles of shit mortgage debts in synthetic CDOs investing in CDS predicated on that debt. They're synthetic because they don't have a stake in the actual underlying debt; just the instruments riding on the coattails. The reason these are so popular (and remain so) is that smart structured attorneys and bankers like your faithful correspondent realized that an even more profitable and efficient way of building high yield products with limited downside was investing in instruments that profit from failure of debt and in instruments that rely on that debt and then hedging that exposure with other CDS instruments in paired trades, and on and on up the chain. The problem with doing this was that everyone wound up exposed to everybody else's books as a result, and when one went tits up, everybody did. Hence, recession, Basel III, etc. Thanks, Obama. Heavy investment in CDS can also have a warping effect on the price of debt (something else that happened during the pre-financial crisis years and is starting to happen again now). This happens in three different ways. (1) Investors who previously were long on the debt hedge their position by selling CDS protection on the underlying, putting downward pressure on the debt price. (2) Investors who previously shorted the debt switch to buying CDS protection because the relatively illiquid debt (partic. when its a bond) trades at a discount below par compared to the CDS. The resulting reduction in short selling puts upward pressure on the bond price. (3) The delta in price and actual value of the debt tempts some investors to become NBTs (neg basis traders) who long the debt and purchase CDS protection. If traders can't take leverage, nothing happens to the price of the debt. If basis traders can take leverage (which is nearly always the case because they're holding a hedged position), they can push up or depress the debt price, goosing swap premiums etc. Anyway. Enough technical details. I could keep going. This is a fascinating topic that is very poorly understood and explained, mainly because the people that caused it all still work on the street and use the same tactics today (it's also terribly taught at business schools because none of the teachers were actually around to see how this played out live). But it relates to the topic of today's lesson, so I thought I'd include it here. Work depending, I'll be back next week with a covenant breakdown. Most upvoted ticker gets the post. *EDIT 1\* In a total blowout, $PLAY won. So it's D&B time next week. Post will drop Monday at market open.
I put together a little cheat sheet of how I think about which trade structure I use for what. This is obviously only covering a small portion of the trade universe but I thought it would be helpful to those a little overwhelmed with the choice within an options chain. The key here is keeping things simple. Knowing what a trade is expressing and how that applies to what you think/hope will happen. That main point is not wasting money with sloppy call or put purchases, and taking what the options market is giving you. Keep it simple, use the expected move and get the universe of trades closer to the binary decisions we make when we trade stock. Here's the full flowchart, bullish, bearish and neutral. You'll notice that it organizes by short premium in the middle and lower probability long premium trades as it gets to the edges (duh) but what I think is helpful is how even on the long premium trades it accounts for selling as much premium as possible to finance that view. (or at least an easier way to think about it) The focus is on 4 common (defined risk, multi-leg) options trades. Call spreads, put spreads, butterflies and condors and when to use them based on your expectations versus the crowd's. This is by no means an exhaustive list of potential trades. But these are a great starting point for those looking to use some smarter trade structures to express directional views. Strikes can of course be adjusted to slightly alter each trade. For instance, a call spread to the expected move can be set to be more in the money to get the breakeven in line with the stock, creating something quite similar to a stock alternative. And as a decision tree on each: Bullish Bearish Neutral Full post here where I go through some examples in CRM and ADBE over on OptionsEye. Let me know if you have any questions or any other ideas of trades you like in similar situations.

Wall Street Week Ahead for the trading week beginning March 9th, 2020
Good Saturday morning to all of you here on wallstreetbets. I hope everyone on this sub made out pretty nicely in the market this past week, and is ready for the new trading week and month ahead. Here is everything you need to know to get you ready for the trading week beginning March 9th, 2020.
Wall Street braces for more market volatility as wild swings become the ‘new normal’ amid coronavirus - (Source)
The S&P 500 has never behaved like this, but Wall Street strategists say get used to it. Investors just witnessed the equity benchmark swinging up or down 2% for four days straight in the face of the coronavirus panic. In the index’s history dating back to 1927, this is the first time the S&P 500 had a week of alternating gains and losses of more than 2% from Monday through Thursday, according to Bespoke Investment Group. Daily swings like this over a two-week period were only seen at the peak of the financial crisis and in 2011 when U.S. sovereign debt got its first-ever downgrade, the firm said. “The message to all investors is that they should expect this volatility to continue. This should be considered the new normal going forward,” said Mike Loewengart, managing director of investment strategy at E-Trade. The Dow Jones Industrial Average jumped north of 1,000 points twice in the past week, only to erase the quadruple-digit gains in the subsequent sessions. The coronavirus outbreak kept investors on edge as global cases of the infections surpassed 100,000. It’s also spreading rapidly in the U.S. California has declared a state of emergency, while the number of cases in New York reached 33. “Uncertainty breeds greater market volatility,” Keith Lerner, SunTrust’s chief market strategist, said in a note. “Much is still unknown about how severe and widespread the coronavirus will become. From a market perspective, what we are seeing is uncomfortable but somewhat typical after shock periods.”
So far, the actions from global central banks and governments in response to the outbreak haven’t triggered a sustainable rebound. The Federal Reserve’s first emergency rate cut since the financial crisis did little to calm investor anxiety. President Donald Trump on Friday signed a sweeping spending bill with an$8.3 billion packageto aid prevention efforts to produce a vaccine for the deadly disease, but stocks extended their heavy rout that day. “The market is recognizing the global authorities are responding to this,” said Tom Essaye, founder of the Sevens Report. “If the market begins to worry they are not doing that sufficiently, then I think we are going to go down ugly. It is helping stocks hold up.” Essaye said any further stimulus from China and a decent-sized fiscal package from Germany would be positive to the market, but he doesn’t expect the moves to create a huge rebound. The fed funds future market is now pricing in the possibility of the U.S. central bank cutting by 75 basis points at its March 17-18 meeting.
Where is the bottom?
Many on Wall Street expect the market to fall further before recovering as the health crisis unfolds. Binky Chadha, Deutsche Bank’s chief equity strategist, sees a bottom for the S&P 500 in the second quarter after stocks falling as much as 20% from their recent peak. “The magnitude of the selloff in the S&P 500 so far has further to go; and in terms of duration, just two weeks in, it is much too early to declare this episode as being done,” Chadha said in a note. “We do view the impacts on macro and earnings growth as being relatively short-lived and the market eventually looking through them.” Deutsche Bank maintained its year-end target of 3,250 for the S&P 500, which would represent a 10% gain from here and a flat return for 2020. Strategists are also urging patience during this heightened volatility, cautioning against panic selling. “It is during times like these that investors need to maintain a longer-term perspective and stick to their investment process rather than making knee-jerk, binary decisions,” Brian Belski, chief investment strategist at BMO Capital Markets, said in a note.
This past week saw the following moves in the S&P:
If you're like us, you've heard a lot of people reference the recent equity declines as a sign that the market is pricing in some sort of Armageddon in the US economy. While comments like that make for great soundbites, a little perspective is in order. Since the S&P 500's high on February 19th, the S&P 500 is down 12.8%. In the chart below, we show the S&P 500's annual maximum drawdown by year going back to 1928. In the entire history of the index, the median maximum drawdown from a YTD high is 13.05%. In other words, this year's decline is actually less than normal. Perhaps due to the fact that we have only seen one larger-than-average drawdown in the last eight years is why this one feels so bad. The fact that the current decline has only been inline with the historical norm raises a number of questions. For example, if the market has already priced in the worst-case scenario, going out and adding some equity exposure would be a no brainer. However, if we're only in the midst of a 'normal' drawdown in the equity market as the coronavirus outbreak threatens to put the economy into a recession, one could argue that things for the stock market could get worse before they get better, especially when we know that the market can be prone to over-reaction in both directions. The fact is that nobody knows right now how this entire outbreak will play out. If it really is a black swan, the market definitely has further to fall and now would present a great opportunity to sell more equities. However, if it proves to be temporary and after a quarter or two resolves itself and the economy gets back on the path it was on at the start of the year, then the magnitude of the current decline is probably appropriate. As they say, that's what makes a market!
Take a good luck at today's moves in long-term US Treasury yields, because chances are you won't see moves of this magnitude again soon. Let's start with the yield on the 30-year US Treasury. Today's decline of 29 basis points in the yield will go down as the largest one-day decline in the yield on the 30-year since 2009. For some perspective, there have only been 25 other days since 1977 where the yield saw a larger one day decline.
That doesn't even tell the whole story, though. As shown in the chart below, every other time the yield saw a sharper one-day decline, the actual yield of the 30-year was much higher, and in most other cases it was much, much higher.
To show this another way, the percentage change in the yield on the 30-year has never been seen before, and it's not even close. Now, before the chart crime police come calling, we realize showing a percentage change of a percentage is not the most accurate representation, but we wanted to show this for illustrative purposes only.
Finally, with long-term interest rates plummetting we wanted to provide an update on the performance of the Austrian 100-year bond. That's now back at record highs, begging the question, why is the US not flooding the market with long-term debt?
Today's decline is pretty much a continuation of what has been a one-way trade for the commodity ever since the US drone strike on Iranian general Soleimani. The last time prices were this low was around Christmas 2018.
With today's decline, crude oil is now off to its worst start to a year in a generation falling 32%. Since 1984, the only other year that was worse was 1986 when the year started out with a decline of 50% through March 6th. If you're looking for a bright spot, in 1986, prices rose 36% over the remainder of the year. The only other year where crude oil kicked off the year with a 30% decline was in 1991 after the first Iraq war. Over the remainder of that year, prices rose a more modest 5%.
Despite strong market gains on Wednesday, March 4, 2020, the on-the-run 10-year Treasury yield ended the day below 1% for the first time ever and has posted additional declines in real time, sitting at 0.92% intraday as this blog is being written. “The decline in yields has been remarkable,” said LPL Research Senior Market Strategist Ryan Detrick. “The 10-year Treasury yield has dipped below 1%, and today’s declines are likely to make the recent run lower the largest decline of the cycle.” As shown in LPL Research’s chart of the day, the current decline in the 10-year Treasury yield without a meaningful reversal (defined as at least 0.75%) is approaching the decline seen in 2011 and 2012 and would need about another two months to be the longest decline in length of time. At the same time, no prior decline has lasted forever and a pattern of declines and increases has been normal.
What are some things that can push the 10-year Treasury yield lower?
A shrinking but still sizable yield advantage over other developed market sovereign debt
Added stock volatility if downside risks to economic growth from the coronavirus increase
A larger potential premium over shorter-term yields if the Federal Reserve aggressively cuts interest rates
What are some things that can push the 10-year Treasury yield higher?
A second half economic rebound acting a catalyst for a Treasury sell-off
As yields move lower, investors may increasingly seek more attractive sources of income
Any dollar weakness could lead to some selling by international investors
Longer maturity Treasuries are looking like an increasingly crowded trade, potentially adding energy to any sell-off
On balance, our view remains that the prospect of an economic rebound over the second half points to the potential for interest rates moving higher. At the same time, we still see some advantage in the potential diversification benefits of intermediate maturity high-quality bonds, especially during periods of market stress. We continue to recommend that suitable investors consider keeping a bond portfolio’s sensitivity to changes in interest rates below that of the benchmark Bloomberg Barclays U.S. Aggregate Bond Index by emphasizing short to intermediate maturity bonds, but do not believe it’s time to pile into very short maturities despite the 10-year Treasury yield sitting at historically low levels.
U.S. Jobs Growth Marches On
While stock markets continue to be extremely volatile as they come to terms with how the coronavirus may affect global growth, the U.S. job market has remained remarkably robust. Continued U.S. jobs data resilience in the face of headwinds from the coronavirus outbreak may be a key factor in prolonging the expansion, given how important the strength of the U.S. consumer has been late into this expansion. The U.S. Department of Labor today reported that U.S. nonfarm payroll data had a strong showing of 273,000 jobs added in February, topping the expectation of every Bloomberg-surveyed economist, with an additional upward revision of 85,000 additional jobs for December 2019 and January 2020. This has brought the current unemployment rate back to its 50-year low of 3.5%. So far, it appears it’s too soon for any effects of the coronavirus to have been felt in the jobs numbers. (Note: The survey takes place in the middle of each month.) On Wednesday, ADP released its private payroll data (excluding government jobs), which increased by 183,000 in February, also handily beating market expectations. Most of these jobs were added in the service sector, with 44,000 added in the leisure and hospitality sector, and another 31,000 in trade/transportation/utilities. Both of these areas could be at risk of potential cutbacks if consumers start to avoid eating out or other leisure pursuits due to coronavirus fears. As shown in the LPL Chart of the Day, payrolls remain strong, and any effects of the virus outbreaks most likely would be felt in coming months.
“February’s jobs report shows the 113th straight month that the U.S. jobs market has grown,” said LPL Financial Senior Market Strategist Ryan Detrick. “That’s an incredible run and highlights how the U.S. consumer has become key to extending the expansion, especially given setbacks to global growth from the coronavirus outbreak.” While there is bound to be some drag on future jobs data from the coronavirus-related slowdown, we would anticipate that the effects of this may be transitory. We believe economic fundamentals continue to suggest the possibility of a second-half-of-the–year economic rebound.
Down January & Down February: S&P 500 Posts Full-Year Gain Just 43.75% of Time
The combination of a down January and a down February has come about 17 times, including this year, going back to 1950. Rest of the year and full-year performance has taken a rather sizable hit following the previous 16 occurrences. March through December S&P 500 average performance drops to 2.32% compared to 7.69% in all years. Full-year performance is even worse with S&P 500 average turning to a loss of 4.91% compared to an average gain of 9.14% in all years. All hope for 2020 is not lost as seven of the 16 past down January and down February years did go on to log gains over the last 10 months and full year while six enjoyed double-digit gains from March to December.
Today’s big rally was an encouraging sign that the markets are becoming more comfortable with the public health, monetary and political handling of the situation. But the history of these “emergency” or “surprise” rate cuts by the Fed between meetings suggest some caution remains in order. The table here shows that these surprise cuts between meetings have really only “worked” once in the past 20+ years. In 1998 when the Fed and the plunge protection team acted swiftly and in a coordinated manner to stave off the fallout from the financial crisis caused by the collapse of the Russian ruble and the highly leveraged Long Term Capital Management hedge fund markets responded well. This was not the case during the extended bear markets of 2001-2002 and 2007-2009. Bottom line: if this is a short-term impact like the 1998 financial crisis the market should recover sooner rather than later. But if the economic impact of coronavirus virus is prolonged, the market is more likely to languish.

Does anyone know of any academic whitepapers or studies on this? They have a rather unique risk profile. I believe I've found +EV divergence in pricing between exchanges, however given I can only trade binary calls I'm left exposed to delta as I can't use straddles. I'd like to hedge my delta for a more pure arbitrage opportunity. Shorting the futures won't work, due to sizing and leaving me uncapped on loss above the strike. I'm looking for serious replies here, I know it's binary options. I believe the recent influx in retail money, small market size and regulatory risk for larger players are creating this opportunity. I'm experienced in algo-trading so if I can get some help on establishing a hedge I'd like to start making a market with what I've found after more testing.
So I've recently gotten back into vertical spreads, which I previously didn't care for too much. I'm watching a TT video about picking the width, where they say they do a minimum of $3 because it will create a binary trade (win or lose, nothing in between). This makes sense, and cuts down on commissions which is great. But, doesn't that expose one to more risk of assignment on the short leg without the long leg covering it? Every once in a while I see a horror story on here or /options where someone got assigned and burned their account because they're effectively controlling $70k in stock (or some other obscene number). Like that $730k RH suicide. Bonus question: why is it always an absolute $ width? For example, in a bull put spread on TSLA, strikes are in $5 increments, and the price of the underlying is obviously very high. Does that satisfy the width criteria for a good spread, or would you want to go wider?
Cover | First chapter | Previous | Patreon | Published Books | Website | Discord “Sarah said you wanted to speak with me?” I strode into Zafir’s office and closed the door behind me. He looked mildly surprised to see me at first, but a welcoming smile took over soon after. “Yes…we have much to discuss.” Zafir watched me carefully as I sat across from him. “First and foremost, I should inform you of Abel’s lie and the steps I took to fix what he’d done.” “Oh lovely. I can’t wait.” I leaned against the armrest. “Do tell me of your noble deeds, o’ great hero.” A short laugh escaped Zafir before he settled back in his seat, hands steepled in his lap, and his voice becoming all business. “To the point it is. Abel, contrary to his reports to me and what he told you, had you fitted with the manner of brain chip that can be detonated. The military recently began investigating Abel’s activities due to his sudden—classified—disappearance. As much of his misconduct was in relation to the other survivors, I took the liberty of ordering additional scans when you were rendered unconscious.” I gave him an impatient look when he paused for a swig of water. “Which showed the chip. And?” “I took the liberty of replacing it. After some discussions with our bosses, I educated them on the nuances of survivors such as yourself and acquired permission to use a Syldrari-made chip.” Zafir gave me that mysterious ‘I know you’re overthinking every word I say’ smile of his. “The survivors, and especially you, require more processing power than the empire’s chips provide. Luckily for us, the empire has no qualms about stealing technology from others and refitting it to suit their own purposes.” “Why Syldrari specifically?” I raised an eyebrow. “There’s plenty of races more advanced than us.” “Because the Syldrari are the most advanced species we’ve encountered, and because a Syldrari chip was the only one you showed compatibility with. I imagine it must have something to do with the Resonance Incident and your Syldrari suit.” Zafir shrugged, seemingly unbothered by my suspicion. “With that explained, we come to the primary reason I sent for you: I want your permission to run further tests. I’m not confident that Abel didn’t fake more information. Specifically, I would like to run blood tests.” “I mean…fine?” I glanced around, then back at Zafir. “Here, or one of the labs?” “Here will suffice.” Zafir motioned for me to roll up my sleeves. He stood and began rummaging around in the nearby cabinets. “How is training progressing?” “It’s…going. There’s not really much to say on that front until they can start actually going out to do…whatever it is we do.” I shook my head. “I’m still waiting to hear back from our bosses, but I did send in my request that Calder, Nikolai, and Maelor begin working.” Zafir pulled a chair up next to me and rolled a tray over, motioning for me to give him my arm. “Speaking of which, they want you to resume patrolling the Syldrari Sector during the day. They believe we’ve given enough time—” “I’m not so sure about that,” I interjected, thinking back to the letter Sarah had brought to me from Rel. “From what I understand, the Syldrari are worryingly convinced that I’m Lethe, and it may be dangerous for me there because of it.” “And you have this on good authority?” Zafir inquired as he gently prodded at my arm, sanitizing it before strapping a thin black band around the crook of my elbow. I grimaced. It was too late not to elaborate. “Rel sent a letter along with our meal the other week. He warned that I should stay away because multiple clans, including the R’selkti, are looking for me due to these rumors.” “Of course…” Zafir sighed, his expression falling. “I’m afraid there’s nothing I can say at this point to make them reconsider…without putting you at greater risk. Tomorrow you will begin your patrols again. I will see if I can convince our superiors to permit one of your colleagues to join you. Either way, I am planning to have one of them act as our ‘vigilante’ in the sector for a time, while you work elsewhere. Who would you say is the most stable?” “Nikolai for sure.” I raised an eyebrow as Zafir took the band off me. “Done already?” “Indeed. It’s much more efficient than a needle.” Zafir tilted a black glass vial, peering into it briefly before capping it off. The other three were quickly sealed as well. If there was anything off about my blood, he didn’t comment or show it. A pity, that. I was curious to know if there were still traces of blue like I’d seen while fighting the odd Syldrari. “Now then, I recommend you rest for the remainder of the day. I want you at your best when dealing with the Syldrari. Perhaps you can do some reading on their culture while you relax?” * * * I arrived in the Syldrari Sector early in the morning as shops were starting to open and people were beginning to walk the streets. Though it was early, there seemed to be an unusual number of people out and about. They were all so distracted that I managed to make it all the way to Rel’s cafe without anyone acknowledging my presence. “Elara? You shouldn’t…” Rel released an aggravated sigh. “You don’t have a choice and that’s why you’re here. Of course. What can I do for you, then? Are you feeling better?” “Better…ish?” I shrugged and gave him a small smile. “What can I say? It’s one thing after another. I’m just trying to roll with the punches at this point.” “Understandable.” Rel nodded and gave me a tired smile. “Will I be surprising you again today?” “Can you stop spoiling the graekstidat fodder for one second?” A familiar, grumpy voice demanded. I glanced over to see a Syldrari man with pale grey skin walking over. His black hair obscured one eye, the pale blue underside glowing against his cheek. His eyes were…among the odder that I’d seen. While the pupils were consistent with Syldrari, the colors of deep mauve, yellow, and jade green blended together similar to how a human’s hazel did. However, I had no damn idea where I’d heard his voice before. “A…what fodder?” I looked over at the aggravated Rel. “And since when did you have an edgy teenager working for you?” “Ah, think of it as an amphibious, furred shark hybrid the length of…several train cars,” Rel answered, pressing his fingers to his temples. “Furthermore, Aldiner is old enough to be your great-great-great-” “I’m working here to pay up for pissing off the elder here,” Aldiner interjected with a snort as he pushed his hands into his apron pockets. He leaned over me, examining me from a few angles. “You don’t have that military air to you. Sure you’re a—” I gave Aldiner my best cold, intimidating glare as he reached out and poked my cheek once. When he went for a second poke, I knocked his arm aside, spun behind him and elbowed him where I hoped his kidneys were, and moved to take him down to the ground. Alas, an arm wrapped around my waist and lifted me clean off the floor—and didn’t stop until my butt was planted on his shoulder. I looked down, startled enough to forget about beating the crap out of Aldiner. “Ignore Aldiner. He likes to annoy everyone he sees, and hates being ignored.” The much larger Syldrari glanced at me. I certainly hadn’t expected it to be the grumpy soldier man, seeing as he’d appeared to rather dislike me. “You’re fast, for a strigaella.” “A human woman,” Rel answered my next question with a sigh. Aldiner, behave. Humans are much less…ah…” Rel motioned with his hands and wiggled his fingers as he searched for the word. “You don’t touch humans unless invited to,” the soldier Syldrari grunted. “She invited ya?” Aldiner leaned forward peering at the soldier and then at where I was perched on his shoulder. “I didn’t, but I can appreciate that he was stopping me from starting a brawl with you right here and—” I cut myself off with an aggravated sigh when felt the feral attempting to push forward. All three Syldrari went still and watched me warily. What they sensed, or how much, I wasn’t sure I wanted to know. “Set me down, please…uh…” “Heh, always bitching about manners and you never introduced yourself, did ya?” Aldiner gave the soldier a cocky grin. “…call me Casair,” the soldier glanced away, seeming a little disgruntled, but the patterns of light on his arms didn’t so much as flicker. …Aldiner on the other hand… I glanced at the self-contained rave fish, then back at Casair. “And you can call me Elara, though I suppose you knew that already.” “Awww, Casair is shy!” Aldiner teased. “Suppressing—” “Quiet, vlerst bait.” Casair crossed his arms at the strobing Syldrari, then glanced over at me. “Back to patrolling needlessly?” “Something like that. I was sitting around recovering for so long that my boss’s bosses started thinking up other uses for me.” I grimaced before walking over to the counter and hopping up onto my usual seat. “As for surprising me, Rel, yes. Though I’d like a glass of…” I paused to reference the menu, “Jiirst☆nil?” Either I said it very right or terribly wrong, because all three men stopped what they were doing to stare at me in shock. Well, Aldiner was staring already, but he didn’t count. “Ah, there you are Rel my dear!” A woman’s voice carried through the room shortly after I heard the doors to the establishment open. “I’ve been looking everywhere for you!” “Mother, please…” a familiar voice groaned, and I glanced back to see the candy girl—who perked up and waved when she spotted me. “Careful you don’t become the queen’s snack,” Casair muttered by my ear before moving away to a booth in the corner, settling into it in such a way that he could keep an eye on everyone. Queen? I eyed the flamboyant woman and the three people with her. If one was her daughter, I had to assume the other two were guards—they had weapons holstered at their hips, at least. “I’m honored by your visit, but please refrain—” Rel began. “So, when will you become one of my consorts?” The…queen? demanded with a bright smile—one that faltered when Rel placed the drink he was making in front of me instead of her. I half-expected her to be angry, but instead she studied me for a moment, her head tilted, and a finger pressed against her full, black-painted lips. “A visitor in the Syldrari Sector…are you an Iri, Sen’iri, Sol’iri, Anad’iri, Sora’iri, or Lun’iri? I can never tell with you humans…” “Elara is an Iri, honestly…” Rel rubbed his temples. “How many times must we explain to you that the humans are binary in their biological—” “And that is just the problem! Biological! If they didn’t hop around between bodies and swap out prosthetics constantly—no offense—perhaps I could more easily identify who they are!” The queen hmphed, crossed her arms, then finally seemed to spot my uniform. “Ah, a military girl—my favorite. If Rel still refuses to become my consort… How would you like off this planet, sweetie?” “Mother, please!” The candy girl moved between her mother and me. “Elara is the nice human I told you about! She likes the candy I make, and her friends are going to help give me ideas for ones more humans will like! Plus, you haven’t even introduced yourself! Humans can’t sense a queen’s identity!” “Speaking of my colleagues,” I paused, pulling out several sheets of paper that had been folded together. “They may not be able to come to the sector for a while, so they asked me to deliver their notes to you.” She took them, and skimmed the first page, the glowing sections of her skin pulsing faster the more she read. “This is…this is great! I’m going to go work on the next batch!” And with that, the excitable candy girl darted out of the café, practically skipping as she went. “I’m Xilen, I run the mercantile Dvarl Clan,” the queen stated promptly, offering me her hand. When I shook it, she paused to study my face and search my eyes. “If you ever want off this planet, Rel knows how to contact me. It wouldn’t do for a pretty little thing like you to be wasted on the humans.” “…I’ll keep that in mind…” I gently reclaimed my hand while Aldiner snickered from somewhere. “Do you find women…?” Rel raised an eyebrow when I shook my head. “Then, you are being polite.” “I’m keeping my options open,” I countered. “If the military can’t recreate the Resonance phenomena—and maybe even if they can—their next step is going to be breeding our mutations down to offspring. I want no part of that, so having options is good.” “Ahhh, she’s so smart!” Xilen leaned over to squeeze me, rubbing her cheek against mine. To my surprise, the Syldrari in the cafe all looked ready to start a fight over it—with her. I got the distinct feeling it wasn’t jealousy, which made me all the more confused. “You just say the word and I’ll have you off this planet and into my arms! I’d love to see how such a cute human would look in Syldrari clothes—you don’t mind translucency, do you? I’d imagine not—” “Elara needs to have her meal before she returns to her duties.” Rel suddenly appeared behind us, his hand on the queen’s shoulder, and his voice cold as ice. “If you’re here to discuss trade, you can wait for me in the usual room.” “How dare—” One of the men I assumed to be the queen’s guards started to raise a weapon. I figured this was as good a time as any to make my point. I was out of my chair and twisting the weapon out of the man’s hand before he could finish his sentence. Using his body weight against him, I got him on the floor and twisted his arm behind his back, placing my booted foot against the back of his shoulders. “You— Ugh!” The other guard grunted when Casair’s fist met his stomach. “Please keep in mind that my job is to keep conflicts in the Syldrari Sector to a minimum, and I am authorized to use lethal force if you pull a weapon on anyone, regardless of race or species,” I spoke calmly, grinding my heel into the Syldrari’s back for emphasis. “You may keep your weapons and use them for defense if necessary. If you pull them again for any other reason…” “Cuuute!” Xilen promptly squeezed me in a hug. It took most of my willpower to beat down the feral, especially since I agreed with the idea of fucking ripping her arms off if she hugged me one more damn time. Xilen leaned down to speak quietly by my ear, “Be careful, dear. If you ever suspect you’re in trouble or in over your head, I’m sure you know how we can get them to come running to save you. And, stay far, far away from the R’selkti and their queen.” “Uh—?” I didn’t get to ask her what the hell she was on about. She fetched her guards and led them to some back room, leaving me confused and…a little unnerved. “I apologize for Queen Xilen’s…eccentricities,” Rel offered when I finally turned around to return to my seat. “Are all queens so goddamn pushy?” I snorted irritably, trying to shove Xilen’s insinuations out of my mind. “Ah…with Iri being the rarest of the six, they tend to act however they please…” Rel murmured awkwardly. “It is not uncommon for Syldrari women to turn their rarity into a form of power over others. Most Iri, even if they are not queens, have many…I believe the human word is ‘spouses?’” “Long story short: most recent queens have been groomed to see the other sexes as playthings to collect. Some of them even take other Iri, but it’s frowned upon,” Casair piped up flatly. “Xilen is of a different tide. She’s lasted so long because she can pretend. Whatever she whispered to you was probably as herself.” “Blah blah blah.” Aldiner rolled his eyes before leaning toward me. “You know, being a queen’s pet has its perks.” “Aldiner!” Rel barked, his markings flaring bright. “Go wash the dishes!” “Fiiine.” Aldiner sauntered off toward the back, though he turned and stuck his fingers up in a V and flicked his surprisingly long dual or split tongue between them before disappearing through the door. …I have a feeling it’s a good thing Rel didn’t catch that… I shook my head slightly. “So, are there any other developments I should know about before I start my patrols again?” “Just…be cautious. Someone has convinced the people here that you are Lethe…and that she may be a queen or related to one.” Rel sighed heavily and pushed his hair back. “Aside from that, things have been calming down after the little queen was found. With Xilen here…who knows. Her unannounced visits always cause trouble.” Next
[Table] Asteroid Day AMA – We’re engineers and scientists working on a mission that could, one day, help save humankind from asteroid extinction. Ask us anything!
Source There are several people answering: Paolo Martino is PM, Marco Micheli is MM, Heli Greus is HG, Detlef Koschny is DVK, and Aidan Cowley is AC.
Can we really detect any asteroids in space with accuracy and do we have any real means of destroying it?
Yes, we can detect new asteroids when they are still in space. Every night dozens of new asteroids are found, including a few that can come close to the Earth.
Regarding the second part of the question, the goal would be to deflect them more than destroy them, and it is technologically possible. The Hera/DART mission currently being developed by ESA and NASA will demonstrate exactly this capability.
I always wanted to ask: what is worse for life on Earth - to be hit by a single coalesced asteroid chunk, or to be hit by a multiple smaller pieces of exploded asteroid, aka disrupted rubble pile scenario?
DVK: This is difficult to answer. If the rubble is small (centimetres to meters) it is better to have lots of small ones – they’d create nice bright meteors. If the rubble pieces are tens of meters it doesn’t help.
Let’s say that hypothetically, an asteroid the size of Rhode Island is coming at us, it will be a direct hit - you’ve had the resources and funding you need, your plan is fully in place, everything you’ve wanted you got. The asteroid will hit in 10 years, what do you do?
DVK: I had to look up how big Rhode Island is – a bit larger than the German Bundesland ‘Saarland’. Ok – this would correspond to an object about 60 km in diameter, right? That’s quite big – we would need a lot of rocket launches, this would be extremely difficult. I would pray. The good news is that we are quite convinced that we know all objects larger than just a few kilometers which come close to our planet. None of them is on a collision course, so we are safe.
the below is a reply to the above
Why are you quite convinced that you know all object of that size? And what is your approach in finding new celestial bodies?
DVK: There was a scientific study done over a few years (published in Icarus 2018, search for Granvik) where they modelled how many objects there are out there. They compared this to the observations we have with the telescopic surveys. This gives us the expected numbers shown here on our infographic: https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained
There are additional studies to estimate the ‘completeness’ – and we think that we know everything above roughly a few km in size.
Thanks for the answer, that's really interesting! It's also funny that the fist Flyeye deployed is in Sicily, at less than 100km from me, I really had no idea
DVK: Indeed, that's cool. Maybe you can go and visit it one day.
the below is a reply to the original answer
What about Interstellar objects however, like Oumuamua?
DVK: The two that we have seen - 'Oumuamua and comet Borisov - were much smaller than the Saarland (or Rhode Island ;-) - not sure about Borisov, but 'Oumuamua was a few hundred meters in size. So while they could indeed come as a complete surprise, they are so rare that I wouldn't worry.
Would the public be informed if an impending asteroid event were to happen? And, how would the extinction play out? Bunch of people crushed to death, knocked off our orbit, dust clouds forever?
DVK: We do not keep things secret – all our info is at the web page http://neo.ssa.esa.int. The ‘risky’ objects are in the ‘risk page’. We also put info on really close approaches there. It would also be very difficult to keep things ‘under cover’ – there are many high-quality amateur astronomers out there that would notice.
In 2029 asteroid Apophis will fly really close to Earth, even closer than geostationary satellites. Can we use some of those satellites to observe the asteroid? Is it possible to launch very cheap cube sats to flyby Apophis in 2029?
DVK: Yes an Apophis mission during the flyby in 2029 would be really nice. We even had a special session on that topic at the last Planetary Defense Conference in 2019, and indeed CubeSats were mentioned. This would be a nice university project – get me a close-up of the asteroid with the Earth in the background!
Go to the section 'resolutions'. This is now a statement that scientists can use to present to their funding agencies, demonstrating that it's not just their own idea.
Thanks for doing this AMA! Did we know the Chelyabinsk meteor in 2013 (the one which had some great videos on social media) was coming? Ig not, how comes? Also, as a little side one, have there been any fatalities from impact events in the past 20 years?
Unfortunately, the Chelyabinsk object was not seen in advance, because it came from the direction of the Sun where ground-based telescopes cannot look.
No known fatalities from impacts have happened in the past 20 years, although the Chelyabinsk event did cause many injuries, fortunately mostly minor.
the below is a reply to the above
How often do impacts from that direction happen, compared to impacts from visible trajectories?
In terms of fraction of the sky, the area that cannot be easily scanned from the ground is roughly a circle with a radius of 40°-50° around the current position of the Sun, corresponding to ~15% of the total sky. However, there is a slight enhancement of objects coming from that direction, therefore the fraction of objects that may be missed when heading towards us is a bit higher.
However, this applies only when detecting an asteroid in its "final plunge" towards the Earth. Larger asteroids can be spotted many orbits earlier, when they are farther away and visible in the night side of the sky. Their orbits can then be determined and their possible impacts predicted even years or decades in advance.
There must be a trade-off when targeting asteroids as they get closer to Earth, is there a rule of thumb at what the best time is to reach them, in terms of launch time versus time to reach the asteroid and then distance from Earth?
DVK: Take e.g. a ‘kinetic impactor’ mission, like what DART and Hera are testing. Since we only change the velocity of the asteroid slightly, we need to hit the object early enough so that the object has time to move away from it’s collision course. Finding out when it is possible to launch requires simulations done by our mission analysis team. They take the strength of the launcher into account, also the available fuel for course corrections, and other things. Normally each asteroid has its own best scenario.
Do you also look at protecting the moon from asteroids? Would an impact of a large enough scale potentially have major impacts on the earth?
DVK: There are programmes that monitor the Moon and look for flashes from impacting small asteroids (or meteoroids) - https://neliota.astro.noa.g or the Spanish MIDAS project. We use the data to improve our knowledge about these objects. These programmes just look at what is happening now.
For now we would not do anything if we predicted a lunar impact. I guess this will change once we have a lunar base in place.
Why aren't there an international organisation comprised of countries focused on the asteroid defence? Imagine like the organisation with multi-billion $ budget and program of action on funding new telescopes, asteroid exploration mission, plans for detection of potentially dangerous NEA, protocols on action after the detection - all international, with heads of states discussing these problems?
DVK: There are international entities in place, mandated by the UN: The International Asteroid Warning Network (http://www.iawn.net) and the Space Mission Planning Advisory Group (http://www.smpag.net). These groups advise the United Nations. That is exactly where we come up with plans and protocols on action. But: They don’t have budget – that needs to come from elsewhere. I am expecting that if we have a real threat, we would get the budget. Right now, we don’t have a multi-billion budget.
the below is a reply to someone else's answer
There is no actual risk of any sizable asteroids hitting earth in the foreseeable future. Any preparation for it would just be a waste of money.
DVK: Indeed, as mentioned earlier, we do not expect a large object to hit is in the near future. We are mainly worried about those in the size range of 20 m to 40 m, which happen on average every few tens of years to hundreds of years. And where we only know a percent of them or even less.
President Obama wanted to send a crewed spacecraft to an asteroid - in your opinion is this something that should still be done in the future, would there be any usefulness in having a human being walk/float on an asteroid's surface?
DVK: It would definitely be cool. I would maybe even volunteer to go. Our current missions to asteroids are all robotic, the main reason is that it is much cheaper (but still expensive) to get the same science. But humans will expand further into space, I am sure. If we want to test human exploration activities, doing this at an asteroid would be easier than landing on a planet.
this is another reply
Yes, but I am slightly biased by the fact that I work at the European astronaut centre ;) There exist many similarities to what we currently do for EVA (extra vehicular activities) operations on the International Space Station versus how we would 'float' around an asteroid. Slightly biased again, but using such a mission to test exploration technologies would definitely still have value. Thanks Obama! - AC
I've heard that some asteroids contains large amounts of iron. Is there a possibility that we might have "space mines" in the far away future, if our own supply if iron runs out?
Yes, this is a topic in the field known as space mining, part of what we call Space Resources. In fact, learning how we can process material we might find on asteroids or other planetary bodies is increasingly important, as it opens up the opportunities for sustainable exploration and commercialization. Its a technology we need to master, and asteroids can be a great target for testing how we can create space mines :) - AC
By how much is DART expected to deflect Didymos? Do we have any indication of the largest size of an asteroid we could potentially deflect?
PM: Didymos is a binary asteroid, consisting of a main asteroid Didymos A (~700m) and a smaller asteroid Didymos B (~150m) orbiting around A with a ~12 hours period. DART is expected to impact Didymos B and change its orbital period w.r.t. Didymos A of ~1%. (8 mins)
The size of Didymos B is the most representative of a potential threat to Earth (the highest combination of probability and consequence of impacts), meaning smaller asteroids hit the Earth more often but have less severe consequences, larger asteroids can have catastrophic consequences but their probability of hitting the earth is very very low.
the below is a reply to the above
Why is there less probability of larger asteroids hitting earth?
DVK: There are less large objects out there. The smaller they are, the more there are.
the below is a reply to the original answer
Is there any chance that your experiment will backfire and send the asteroid towards earth?
PM: Not at all, or we would not do that :) Actually Dimorphos (the Didymos "moon") will not even leave its orbit around Didymos. It will just slightly change its speed.
I'm sure you've been asked this many times but how realistic is the plot of Armageddon? How likely is it that our fate as a species will rely on (either) Bruce Willis / deep sea oil drillers?
Taking into consideration that Bruce Willis is now 65 and by the time HERA is launched he will be 69, I do not think that we can rely on him this time (although I liked the movie).
HERA will investigate what method we could use to deflect asteroid and maybe the results will show that we indeed need to call the deep sea oil drillers.
the below is a reply to the above
So then would it be easier to train oil drillers to become astronauts, or to train astronauts to be oil drillers?
I do not know which one would be easier since I have no training/experience of deep see oil drilling nor becoming an astronaut, but as long as the ones that would go to asteroid have the sufficient skills and training (even Bruce Willis), I would be happy.
If budget was no object, which asteroid would you most like to send a mission to?
Nice question! For me, I'd be looking at an asteroid we know something about, since I would be interested in using it for testing how we could extract resources from it. So for me, I would choose Itokawa (https://en.wikipedia.org/wiki/25143_Itokawa), which was visited by Hayabusa spacecraft. So we already have some solid prospecting carried out for this 'roid! - AC
this is another reply
Not sure if it counts as an asteroid, but Detlef and myself would probably choose ʻOumuamua, the first discovered interstellar object.
the below is a reply to the above
Do we even have the capability to catch up to something like that screaming through our solar system? That thing has to have a heck of a velocity to just barrel almost straight through like that.
DVK: Correct, that would be a real challenge. We are preparing for a mission called 'Comet Interceptor' that is meant to fly to an interstellar object or at least a fresh comet - but it will not catch up with it, it will only perform a short flyby.
After proving to be able to land on one, could an asteroid serve as a viable means to transport goods and or humans throughout the solar system when the orbit of said asteroid proves beneficial. While it is probably quite problematic to land the payload, it could save fuel or am I mistaken?
Neat idea! Wonder if anyone has done the maths on the amount of fuel you would need/save vs certain targets. - AC
PM: To further complement, the saving is quite marginal indeed because in order to land (softly) on the asteroid you actually need to get into the very same orbit of that asteroid . At that point your orbit remains the same whether you are on the asteroid or not..
can the current anti-ballistic missiles systems intercept a terminal phase earth strike asteroid? or it is better to know beforehand and launch an impacting vehicle into space?
DVK: While I do see presentations on nuclear explosions to deflect asteroids at our professional meetings, I have not seen anybody yet studying how we could use existing missile systems. So it's hard to judge whether existing missiles would do the job. But in general, it is better to know as early as possible about a possible impact and deflect it as early as possible. This will minimize the needed effort.
How much are we prepared against asteroid impacts at this moment?
DVK: 42… :-) Seriously – I am not sure how to quantify ‘preparedness’. We have international working groups in place, mentioned earlier (search for IAWN, SMPAG). We have a Planetary Defence Office at ESA, a Planetary Defense Office at NASA (who spots the difference?), search the sky for asteroids, build space missions… Still we could be doing more. More telescopes to find the object, a space-based telescope to discover those that come from the direction of the Sun. Different test missions would be useful, … So there is always more we could do.
Have you got any data on the NEO coverage? Is there estimations on the percentage of NEOs we have detected and are tracking? How can we improve the coverage? How many times have asteroids been able to enter earths atmosphere without being detected beforehand?
As expected, we are now nearly complete for the large ones, while many of the smaller ones are still unknown.
In order to improve coverage, we need both to continue the current approach, centered on ground-based telescopes, and probably also launch dedicated telescopes to space, to look at the fraction of the sky that cannot be easily observed from the ground (e.g., towards the Sun).
Regarding the last part of your question, small asteroids enter the Earth atmosphere very often (the infographics above gives you some numbers), while larger ones are much rarer.
In the recent past, the largest one to enter our atmosphere was about 20 meters in diameter, and it caused the Chelyabinsk event in 2013. It could not be detected in advance because it came from the direction of the Sun.
We have however detected a few small ones before impact. The first happened in 2008, when a ~4-meter asteroid was found to be on a collision course less than a day before impact, it was predicted to fall in Northern Sudan, and then actually observed falling precisely where (and when) expected.
this is another reply
DVK: And to add what MM said - Check out http://neo.ssa.esa.int. There is a ‘discovery statistics’ section which provides some of the info you asked about. NASA is providing similar information here https://cneos.jpl.nasa.gov/stats/. To see the sky which is currently covered by the survey telescopes, you need to service of the Minor Planet Center which we all work together with: http://www.minorplanetcenter.org, ‘observers’, ‘sky coverage’. That is a tool we use to plan where we look with our telescopes, so it is a more technical page.
Are there any automatic systems for checking large numbers of asteroids orbits, to see if the asteroid's orbit is coming dangerously close to Earth, or is it done by people individually for every asteroid? I ask it because LSST Rubin is coming online soon and you know it will discover a lot of new asteroids.
Yes, such systems exist, and monitor all known and newly discovered asteroids in order to predict possible future impacts.
It is automatically updated every day once new observational data is processed.
What are your favourite sci-fi series?
DVK: My favorites are ‘The Expanse’, I also liked watching ‘Salvation’. For the first one I even got my family to give me a new subscription to a known internet streaming service so that I can see the latest episodes. I also loved ‘The Jetsons’ and ‘The Flintstones’ as a kid. Not sure the last one counts as sci-fi though. My long-time favorite was ‘Dark Star’.
this is another reply
Big fan of The Expanse at the moment. Nice, hard sci-fi that has a good impression of being grounded in reality - AC
this is another reply
When I was a kid I liked The Jetsons, when growing up Star Trek, Star wars and I also used to watch with my sister the 'V'.
When determining the potential threat of a NEA, is the mass of an object a bigger factor or size? I'm asking because I'm curious if a small but massive object (say, with the density of Psyche) could survive atmospheric entry better than a comparatively larger but less massive object.
The mass is indeed what really matters, since it’s directly related with the impact energy.
And as you said composition also matters, a metal object would survive atmospheric entry better, not just because it’s heavier, but also because of its internal strength.
What are your thoughts on asteroid mining as portrayed in sci-fi movies? Is it feasible? If so would governments or private space programs be the first to do so?What type of minerals can be found on asteroids that would merit the costs of extraction?
Certainly there is valuable stuff you can find on asteroids. For example, the likely easiest material you can harvest from an asteroid would be volatiles such as H2O. Then you have industrial metals, things like Iron, Nickel, and Platinum group metals. Going further, you can break apart many of the oxide minerals you would find to get oxygen (getting you closer to producing rocket fuel in-situ!). Its feasible, but still needs alot of testing both here on Earth and eventually needs to be tested on a target. It may be that governments, via agencies like ESA or NASA, may do it first, to prove the principles somewhat, but I know many commercial entities are also aggresively working towards space mining. To show you that its definitely possible, I'd like to plug the work of colleagues who have processed lunar regolith (which is similar to what you may find on asteroids) to extract both oxygen and metals. Check it out here: http://www.esa.int/ESA_Multimedia/Images/2019/10/Oxygen_and_metal_from_lunar_regolith
Will 2020's climax be a really big rock?
DVK: Let's hope not...
Considering NASA, ESA, IAU etc. is working hard to track Earth-grazing asteroids, how come the Chelyabinsk object that airburst over Russia in 2013 came as a total surprise?
The Chelyabinsk object came from the direction of the Sun, where unfortunately ground-based telescopes cannot look at. Therefore, it would not have been possible to discover it in advance with current telescopes. Dedicated space telescopes are needed to detect objects coming from this direction in advance.
the below is a reply to the above
Is this to say that it was within specific solid angles for the entire time that we could have observed it given its size and speed?
Yes, precisely that. We got unlucky in this case.
Have any of you read Lucifer's Hammer by Larry Niven? In your opinion, how realistic is his depiction of an asteroid strike on Earth?
DVK: I have – but really long ago, so I don’t remember the details. But I do remember that I really liked the book, and I remember I always wanted to have a Hot Fudge Sundae when reading it.
I was thinking about the asteroid threat as a teen and came up with this ideas (Hint: they are not equally serious, the level of craziness goes up real quick). Could you please comment on their feasibility? 1. Attaching a rocket engine to an asteroid to make it gradually change trajectory, do that long in advance and it will miss Earth by thousands of km 2. Transporting acid onto asteroid (which are mainly metal), attaching a dome-shaped reaction chamber to it, using heat and pressure to then carry out the chemical reaction to disintegrate asteroids 3. This one is even more terrible than a previous one and totally Dan Brown inspired — transporting antimatter on asteroid, impacting and causing annihilation. Thank you for this AMA and your time!
DVK: Well the first one is not so crazy, I have seen it presented... the difficulty is that all asteroids are rotating in one way or another. So if you continuously fire the engine it would not really help. You'd need to switch the engine on and off. Very complex. And landing on an asteroid is challenging too. Just using the 'kinetic impactor' which we will test with DART/Hera (described elsewhere in this chat) is simpler. Another seriously proposed concept is to put a spacecraft next to an asteroid and use an ion engine (like we have on our Mercury mission BepiColombo) to 'push' the asteroid away.
As for 2 and 3 I think I will not live to see that happening ;-)
What is the process to determine the orbit of a newly discovered asteroid?
The process is mathematically quite complex, but here's a short summary.
Everything starts with observations, in particular with measurements of the position of an asteroid in the sky, what we call "astrometry". Discovery telescopes extract this information from their discovery images, and make it available to everybody.
These datapoints are then used to calculate possible trajectories ("orbits") that pass through them. At first, with very few points, many orbits will be possible.
Using these orbits we can extrapolate where the asteroid will be located during the following nights, use a telescope to observe that part of the sky, and locate the object again.
From these new observations we can extract new "astrometry", add it to the orbit determination, and see that now only some of the possible orbits will be compatible with the new data. As a result, we now know the trajectory better than before, because a few of the possible orbits are not confirmed by the new data.
The cycle can then continue, with new predictions, new observations, and a more accurate determination of the object's orbit, until it can be determined with an extremely high level of accuracy.
What are some asteroids that are on your "watchlist"?
It's called "risk list", and it includes all known asteroids for which we cannot exclude a possible impact over the next century. It is updated every day to include newly discovered asteroids, and remove those that have been excluded as possible impactors thanks to new observations.
the below is a reply to the above
That's quite a list!! Do you guys ever feel stressed or afraid when you have to add another dangerous candidate (and by dangerous I mean those above 200m) is added to this Risk List?
Yes, when new dangerous ones are added it's important that we immediately do our best to gather more data on them, observing them with telescopes in order to get the information we need to improve our knowledge of their orbit.
And then the satisfaction of getting the data needed to remove one from the list is even greater!
What inspired you to go into this field of study?
I was fascinated by astronomy in general since I was a kid, but the actual "trigger" that sparked my interest in NEOs was a wonderful summer course on asteroids organized by a local amateur astronomers association. I immediately decided that I would do my best to turn this passion into my job, and I'm so happy to have been able to make that dream come true.
this is another reply
DVK: I started observing meteors when I was 14, just by going outside and looking at the night sky. Since then, small bodies in the solar system were always my passion.
As a layperson, I still think using nuclear weapons against asteroids is the coolest method despite better methods generally being available. Do you still consider the nuclear option the cool option, or has your expertise in the field combined with the real-life impracticalities made it into a laughable/silly/cliche option?
DVK: We indeed still study the nuclear option. There are legal aspects though, the ‘outer space treaty’ forbids nuclear explosions in space. But for a large object or one we discover very late it could be useful. That’s why we have to focus on discovering all the objects out there as early as possible – then we have time enough to use more conventional deflection methods, like the kinetic impactor (the DART/Hera scenario).
It seems like doing this well would require international cooperation, particularly with Russia. Have you ever reached out to Russia in your work? Do you have a counterpart organization there that has a similar mission?
DVK: Indeed international cooperation is important - asteroids don't know about our borders! We work with a Russian team to perform follow-up observations of recently discovered NEOs. Russia is also involved in the UN-endorsed working groups that we have, IAWN and SMPAG (explained in another answer).
If multiple videos or pictures, taken from different locations, are available, then it's possible to reconstruct the trajectory, and extrapolate where the object came from.
Regarding the composition, it's a bit more difficult if nothing survives to the ground, but some information can be obtained indirectly from the fireball's color, or its fragmentation behavior. If a spectral analysis of the light can be made, it's then possible to infer the chemical composition in much greater detail.
I've always wanted to know what the best meteorite buying site is and what their average price is??
DVK: Serious dealers will be registered with the 'International Meteorite Collectors Association (IMCA)' - https://www.imca.cc/. They should provide a 'certificate of authenticity' where it says that they are member there. If you are in doubt, you can contact the association and check. Normally there are rough prices for different meteorite types per gram. Rare meteorites will of course be much more expensive than more common ones. Check the IMCA web page to find a dealer close to you.
Just read through Aidans link to the basaltic rock being used as a printing material for lunar habitation. There is a company called Roxul that does stone woven insulation that may be able to shed some light on the research they have done to minimize their similarity to asbestos as potentially carcinogenic materials deemed safe for use in commercial and residential applications. As the interior surfaces will essentially be 3D printed lunar regolith what are the current plans to coat or dampen the affinity for the structure to essentially be death traps for respiratory illness?
At least initially, many of these 3d printed regolith structures would not be facing into pressurised sections, but would rather be elements placed outside and around our pressure vessels. Such structures would be things like radiation shields, landing pads or roadways, etc. In the future, if we move towards forming hermetically sealed structures, then your point is a good one. Looking into terrestrial solutions to this problem would be a great start! - AC
What kind of career path does it take to work in the asteroid hunting field?
It's probably different for each of us, but here's a short summary of my own path.
I became interested in asteroids, and near-Earth objects in particular, thanks to a wonderful summer course organized by a local amateur astronomers association. Amateur astronomers play a great role in introducing people, and young kids in particular, to these topics.
Then I took physics as my undergrad degree (in Italy), followed by a Ph.D. in astronomy in the US (Hawaii in particular, a great place for astronomers thanks to the exceptional telescopes hosted there).
After finishing the Ph.D. I started my current job at ESA's NEO Coordination Centre, which allowed me to realize my dream of working in this field.

DVK: Almost all of us have a Master's degree either in aerospace engineering, mathematics, physics/astronomy/planetary science, or computer science. Some of us - as MM - have a Ph.D. too. But that's not really a requirement. This is true for our team at ESA, but also for other teams in other countries.
What is the likelihood of an asteroid hitting the Earth In the next 200 years?
Have you played the Earth Defence Force games and if you have, which one is your favourite?
No I have not played the Earth Defence Force games, but I just looked it up and I think I would liked it. Which one would you recommend?
How close is too close to earth? Space is a SUPER vast void so is 1,000,000 miles close, 10,000,000? And if an asteroid is big enough can it throw earth off its orbit?
DVK: Too close for my taste is when we compute an impact probability > 0 for the object. That means the flyby distance is zero :-) Those are the objects on our risk page http://neo.ssa.esa.int/risk-page.
If an object can alter the orbit of another one, we would call it planet. So unless we have a rogue planet coming from another solar system (verrry unlikely) we are safe from that.
Are you aware of any asteroids that are theoretically within our reach, or will be within our reach at some point, that are carrying a large quantity of shungite? If you're not aware, shungite is like a 2 billion year old like, rock stone that protects against frequencies and unwanted frequencies that may be traveling in the air. I bought a whole bunch of the stuff. Put them around the la casa. Little pyramids, stuff like that.
DVK: If I remember my geology properly, Shungite forms in water sedimental deposits. This requires liquid water, i.e. a larger planet. So I don't think there is a high chance to see that on asteroids.
