The Remarkable Frequency of Once in a Lifetime Events

The Interview ·
Featuring Gontran de Quillacq and Michael Green

Published on: May 19th, 2020 • Duration: 47 minutes

Pension funds and the hedge fund managers who invest on their behalf are trusted with the retirement savings of everyday people and that trust is based on the idea that those "experts" fully understand the risks that they are taking. Gontran de Quillacq, practitioner and expert witness for Navesink International, is the expert to the experts. When funds blow up and pensioners are left holding the bag, he can step in and testify as to whether these experts were actually behaving like amateurs or the victims of an unpredictable black swan event. In this conversation with Michael Green of Logica Capital Advisers, Gontran touches on his decades of experience trading complex and esoteric assets to explain why many of the models and common risk metrics like Sharpe ratio don't capture the full picture of the risks that certain strategies employ. They examine how the recent sell-off has brought forward many of these risks, shown that once in a lifetime events tend to happen much more frequently than the models would suggest, and left behind the remains of fund managers who to the untrained eye looked like the smartest guys in the room. Filmed on May 14, 2020.

    Mike is one of the main reasons I subscribe to RV. I appreciate the time in effort he puts into becoming a true subject matter expert diving through academic papers and regulatory filings. Not only does he question commonly held views in the world of finance, but he backs up his arguments with facts, research etc., not speculation. In a world where you see people take short cuts everywhere from corporate decisions, to investments, to media stories .. he is a breath of fresh air. I encourage everyone to check out his funds latest research on the value factor. Keep it up.

    For those of us who think the world is Central Limit Theorem, I've been perplexed with the frequency of "perfect storm" or "once in a lifetime events". I must have lived 4 or 5 lifetimes already! This interview helped explain how this can happen, and reminds me that many events you are interested in tracking, need to be measured indirectly through behind the scene metrics and CANNOT be directly measured. (No quantum mechanics analogies, please!)

      I would like to see them consider Chris's "100 Year" Dragon Portfolio against Mike's point about how knowledge of past behavior leads to changes in future behaviors. We can design a portfolio that holds up well over past regimes in simulation, but what tells us markets will revisit the same regimes, in a world where everyone has access to those same lessons of history?

      22 May 2020 @ 12:29
      Jon, if you're starting out, at the very beginning diving head first into the Black Scholes is not necessarily going to be the quickest way to learn practival lessons. Also at the beginning avoid diving into explanations of the Greeks, i.e. Delta, Theta, Vega, Gamma being the primary ones. At this point your probably thinking to yourself "is this guy is on drugs". There is a simplier way to grasp an understanding of how it all fits together. At first simply focus on achieving a through understanding of EXTRINSIC value. Read up on the definition of extrinsic value then move onto the following. Pull up an Options Chain on your brokerage platform, edit the columns to show extrinsic value. Start with ATM and note the EXT value. Now keeping the same ATM strike move the CYCLE further out in time and notice how the EXT value changes. Next move the cycle closer and closer to expiry noticing how the EXT value changes the closer to expiry you get. Next thing to do, move away from ATM moving up or down in your Option Chain strike e.g. further out of the money, or futher in the money ITM simulating directional change, each time noticing how EXTRINSIC value alters. Do all of the above on the CALL side and the PUT side noticing how EXT moves. An enhancment might be to include INTRINSIC value in the display configuration of your option chain. Once you've grasped the basics of how EXTRINSIC moves upon changes in time and direction, without possibly realising it, you've just taught yourself an important aspect of how Black Scholes spits out the price of an Option. Upon nailing EXT understanding, move onto adding Delta, Theta, Gamma, Vega to your option chain display config and continue the above process. Best of luck.

    Gontran please correct me if my logic is wrong here. This WSJ article from November 2019 had the Bridgewater notional of the put trade at about USD100bn. While the catalyst for the selloff was CoVID19 as it got to the strike prices around 2600-2650 the last few hundred points down to the 2192 low or about 15% based off 2600 is potentially due to negative convexity from short gamma and vega postions to do with the Bridgewater trade that had to be delta hedged when we were seeing multiple days of moves close to 10%? With a notional of USD100bn these amounts would be huge. For me the last 400-500 points move down to 2192 is what freaked central bankers, govt's and regulators out and made them move very quickly. If this is the case the last 15% was an over extension on a massive scale to stay within risk limits or tolerances in a market where the long vega, gamma position went unhedged ( and potentially depending on maturity date out of the money since the subsequent index rally) but the short position had to be hedged so they ended up losing alot of money from the hedging. I've seen this before but only in smaller cases but this seems to potentially have had flow on effects to central bank action and economy wide confidence if the above is the case. If this were true I am more bullish being outright long the index here.

      Yes. You are correct. The options of the $bn purchase were at that level and had become very short dated at that time. The market was extremely short gamma and surely exacerbated the market's fundamental revaluation. It resulted into two 10% moves (one down, one up). There was a 7+% move as well, if my memory serves.

    since the inception of RV I have found Mike Green always worth watching, articulate, easy to understand certainly at the top table of people RV use or interview. However on this particular occasion the conversation was not balanced. Whilst everything the guys said about the risks of having a portfolio with Negative Vega (short volatility) is correct, what they said I'm fine with, however it's what they didn't say leaves the conversion as un-balanced, one sided only. Of course when recently the VIX hit 82.99 any existing short premium/short volatility postions were hit hard (mine included) but in the last 10 years there have been only 5 occasions, 5 short lived clusters in time of VIX being above 50. So if selling options is all so risky, an inquisitive mind might think "then why do so many people do it". Put simply, once educated, most of the time, in excess of 75% of the time it works, as the options seller has a huge advantage over the option buyer. There is much mis-understanding about the benefits of selling options made possible by the lack of education. A quick search "options education' will take people down a rat hole, much of it highly dubious, and even the better stuff after the intial 'introduction offer' soon moves onto having to pay money to access the 'unbelievable value good, get rich quick material' . The primary challege of understading the massive potential of Options, particulary for those will to do the work first, the hugh potential of selling options, it takes a lot of hard graft and dedication to become competent, I believe at least two years, it even takes 3 months of daily immersion in the subject to learn elementary basics. Most people are not prepared to undertake such a long journey so they comfort themselves by thinking "don't need to do all that ..... as I've seen countless sources saying selling options is really a bad idea, so they believe what the 'experts' say take it at face value, therefore they never learn as they never even try. I believe the best introduction level education material, all entirely free, maybe found here Even this material takes approx 12 hours to work through. My portfolio has short vega, and I took a hit recently, however even my underfined risk positions, whilst the losses were painful, they were not life threatening made possible by two very simple 'rules'. Even the losses on my undefined risk positions never exceeded Buying Power Reduction, as said still very painful, but possible to recover. 1./ the only protection against a sudden and violent move up in Volatility to ensure losses are manageable so one can live to fight another day is KEEP SIZE SMALL, as options are leveraged instruments my max limit of Capital Deployed is 30% of Net Liq. Such a percentage would be completely hopeless with a purely long/short stocks portfolio. 2./ Every day I managed/adjust positions to ensure portfolio is always set up Directionally short. This is a drag on performance, but will/did back in March help mitigate the level of losses so avoiding a catastrophic experience. For me trading volatility has nothing to do with using ETF's with the word volatility attached, or trying to get cute with Trading VIX options. There is one viable volatility ETF, but only in certain circumstances, and that is VXX and rarely used. For me short vol, collecting premium by selling options leading to the creation of a short volatility (short Vega) portfolio means repeatedly selling options in ONLY the most highly liquid Stocks or ETF's, with the 'richest' (expensive) out of the money Options during specific periods of elevated individual stock Implied Volatility (again aka think expensive). At the time of writing, using option pricing from last nights close these included AAPL, SBUX, MSFT, FB, BABA, DIS, SLV, IWM, XLE, C, GDX plus numerous others. Last thing, before anyone posts a GOTCHA comment regarding GAMMA risk facing short volatility positions, GAMMA risk is almost totally avoided by closing early, approx three weeks before expiry.

      Hi Mike. I'm not massively experienced with option hedging as my mandate prevents me going short options generally but on Gamma risk even though you could close your position out a few weeks before expiry would that risk not still exist somewhere with market participants? If the original buyer of the options in size wasn't hedging this then for the hedging being undertaken into expiry for atm options in the market the flows would be imbalanced from the hedging flows being undertaken by those short the options and cause extended changing ranges in the underlying instrument?

      Bryan, I had to read your question more than once :-) You raise an excellent topic, a detailed response I'm not qualified to answer, but here's a small contribution for what's it worth. Please note I would not be comfortable standing up on a crowded room to deliver the following. For liquid underlyings all our orders don't get filled at the Exchange as such; the other side is an HFT Market Maker. If a M.M. decides to take a defined risk Options trade e.g. Iron Condor they will instantly "FILL'' to ensure their 'execution times' are meeting the SLA's they have in place with the Brokerages they're paying money to receive Broker order flow. Accepting define risk is done all WITHOUT hedging the specfic position at the precise moment of order execution, it simply goes into their overall bucket of N x Millions/Billions of positions where they constantly manage their overall Book, e.g. keeping their Directional exposure 'flat'/Delta Neutral, and of course managing their Gamma Exposure. Market Makers mitigating Gamma exposure is the domain of the real professionals, ( it isn't of course human beings doing the execution but computers, all made possible by armies of coders and state of the art hardware infrastruture) basically it's fundamental to their operational model, I'm not qualfied to comment on how they do it at the scale they do it as I believe Gamma mitigation is their Intellectual Property Crown Jewels and such secrets are closely guarded. Citadel, Jump etc are highly impressive Market Making operations. Unless someone can get Ken Griffin to open up - never going to happen - the rest of us can only wonder how they do it. With an undefined risk Naked Option trade, a different decision logic will be applied. The Market Maker will if deciding to accepting a naked option also instantly hedge their exposure, if effect when your short Naked Option shows as filled. the MM has already got it hedged. I'll leave it there as I don't want to stray into 'ballshit' territory. Hope my comments at least provides some marginal level of value. As an aside, HFT conjours up many a consiracy theory, they're Devils, it must be banned etc. in reality, Market Makers that use HFT, are the key to Market Structure viability, the very essence of why Option Markets are efficient. They help drive down cost's of trading, and ensure essential liquidity.

      Selling naked calls is super dangerous. Much more dangerous than selling naked puts. My logic goes, I won’t be upset if I am assigned an AAPL put well below strike because AAPL won’t disappear overnight and I can write calls immediately on the newly acquired shares. However, if I leverage up and sell naked calls...should the price rocket pst the strike, and I don’t have cash to cover - I am fffffff’ed! Currently writing $SPY puts at 185 to expire Dec 31st. Should SPY dip too low, I’ll roll it into the next quarter. With good timing, it’s actually possible to collect time decay that’s as much or more than my original required premium - and sometimes much earlier than expected. However, $SPY is risky too - believe it or not the ETF is a giant trust fund controlled by 11 millennials that inherited it.

      I would rather say that short vol strategies is what is flagged for caution and pros ie short calls or short puts is where you should stay away if you're not a pro. Long calls and puts entails you have paid off the full downside or negative equity of the position at inception.

      Also, this is why I only write puts on $spy when it drops, then roll that position deeper into the future. Learned to collect time decay. If I earn 45% of a premium in 2 days when it’s supposed to expire in 50, why would I wait additional 48 days? Roll deep put sells far enough and time decay will seriously reward you. I write DEEP OTM $SPY puts. Everything follows spy, anyway so why play roulette with other equities which aren’t a penny wide?

      Depends. Put writing premiums maxed out in March and many premiums decayed values greater than their pre-March highs. However, buying the puts to close at a lower price would count as short term investment which may not fit with your clients risk reward paradigm. Writing puts on a stable equity is ok, and in my experience time decay can reward you month to month or quarter to quarter very well. However, per the examples in this interview, a .10 put is not smart - earning $10/contract a day is worthless. However, at the March lows, some put bids experienced 1000% value changes, and expired 800% back to their original bids by April. Options are complex.

It is a gift to be able to make a complicated topic accessible to a broad audience without dumbing it down. As a lawyer, I totally understand why Mr. Quillacq, in addition to his knowledge and experience, makes a perfect expert witness. Mr. Green outdoes himself in this interview, demonstrating deep knowledge and enabling the audience to access this great conversation. RV team would be great if Mr. Green shared the papers, or at least the titles, that he had shared to Mr. Quillacq to allow us to get more context to this interview? For sure many of us will be back to listen again armed with more background.

      As someone who discovered RV in my college years this was my favorite aspect of the platform. Being exposed to what you don't know is the first step in understanding it. Every hour of RV I watched meant 3 hours of reading and at least one more rewatch to fully understand it. 3 hours turned to 2 hours, then 1 and eventually 0.

    Extremely high level stuff, selling VIX options with leverage based on projections of low vol just seems like asking for trouble. It in a good way symbolizes short term narrative, where as long as we can money from a 3-4 year perspective, who cares if we go bust. I would attribute this in part to career risk aspect, where if you do good for a few years you get promoted and some other schmuck is left cleaning up the cluster f you made. And oh ya, cant forget my standard lines, Bitcoin fixes this, stay humble stack sats.

    Thank you Mike & Gontran! Found this very useful as I've recently started my journey learning about the options space.

    Great interview. It has been too long from college days for me to understand the underlying mathematics. I can understand the net, net of the derivative market being radically different from the equity market. Derivative markets are the deep end of the pool even for Goldman Sachs post grads to dive into. How many of the last market meltdowns have been caused by unrecognized tail-risk events from derivatives? In one way or the other, most probably. Big thanks to Mr. Green for continuing to look at the fundamental problems of the markets from derivatives to pension funds. The San Francisco tugboat captain was an excellent analogy. A similar analogy would be a steamboat captain on the mighty Mississippi a la Mark Twain. Both very experienced and knowledgeable hands. DLS

      No mate - these guys just both happen to be extremely bright and this was a highly technical conversation.

    People who short vol don’t understand the difference between time and ensemble probabilities.

    Amazing. I wasn't expect this level of discussion into gamma, liquidity risk and suitability of instruments depending on depth of experience of the people trading in it. Completely agree that in the period of low volatility, the risk at the tails completely changes the entire risk profile and mostly due to our own doing. All the talks are great but this one is positive gamma at no extra cost. Thank you and congrats!

    Thanks for the excellent interview. I think the problem is that the tail risk is not taught in schools and without exposure to it, one can end up looking at linear charts that really are logarithmic in potential losses.

    Is it possible to lose more than the per share value of a retail ETF? I.e. can you end up owing money? And is there a simple way to determine that when assessing whether to buy shares of an etf.?
