The corner of finance Twitter or #fintwit that is concerned with options (#voltwit) is a melee lately. There’s passive aggression in the form of subtweets and outright battles on people’s timelines. I won’t re-hash the feuds but there are 2 categories of accounts catching heat:
A few thoughts about this:
With that context, here’s a few related links:
3 key ideas:
1. “Prepare not predict”
You don’t know what the future holds, so you should diversify for all weather
2. The recency bias in almost all investing advice you see today
The conventional wisdom in the US would look nothing like what the Japanese believe. Sure, we might be exceptional, and there are many differences between the US and other developed nations. But if that’s your bet, at least know that you are making it and not ignoring broader base rates.
3. Sharpe ratio is useful at the portfolio level, not individual investment level.
He uses a powerful and correct analogy. Your portfolio is a team of complementary players (investments). If they are all scorers your team cannot win in the long-run. Long vol and long tail strategies look terrible in isolation. If you fail to appreciate the impact of convexity and correlation in portfolio construction, you don’t understand diversification. You are a baby who can’t reach the pedals. A good starting place for learners is The Diversification Imperative.
Overall the episode is an outstanding reference. It’s one of the first places I’d point a novice who was starting to learn about portfolio construction. That said, there is one section that I (and probably other vol folk) find distracting to the whole message, but it should not lessen your view of Chris’ understanding of proper diversification. [That’s the section about back-fitting vol surfaces to extend the history of options to a time before they were listed. The purpose is to backtest a vol allocation. But since options markets are forward-looking any constructed implied vol history is doing more hand-waving than a pageant winner. Backtesting a vol allocation even with the official history is a highly speculative exercise since options markets have evolved so much. I’d have little confidence in any assumptions about liquidity and slippage to say the least.]
2. Quantian’s critique is sophisticated because Quantian understands the value of tail strategies:
I love tail risk funds, and I love the idea of diversifying with a high-vol, convex asset. But this isn’t that! This barely has more vol than a t-bill. It’s *less* volatile than a 30-year zero. You need to allocate a *huge* chunk of capital to this to have it work. If you had a fund which was routinely posting +30%, +40% months in a crisis, and was +100% in March, then that’s absolutely worth paying 2 and 20 for a 5-10% position in. But if you’re a vol fund up a measly 150 bps in Feb of 2018? That’s not worth the price of admission. If you are selling tail risk insurance, it needs to be as capital efficient as possible to allow your investors to maximize their beta exposure elsewhere. Imagine if insurance required you to post collateral equal to half the car’s value- nobody would buy it, it’s not insurance.
3. Chris responds head-on to Quantian’s critiques but in private. Here’s what Quantian revealed:
Let it be known that Chris has graciously responded to my questions about vehicle structure to a sufficient degree that I consider this beef “squashed”. The fund is a small component of assets relative to SMA overlays, which are adjusted to fit the client and perform quite well
Quantian’s “apology” is pretty on-brand:
I do consider the willingness to engage with anonymous trolls on Twitter, many of whom live in basement apartments and drink Leoville-Las Cases because they cannot afford Latour, to be a positive characteristic in an investment manager, so he gets bonus points for that too.
Chris has been building a brand in public for over a decade, he’s a popular speaker at vol conferences and well-respected within the industry. On the one hand, you could say what Quantian basically said: for an investment manager to indulge an “anonymous troll” is gracious. But it’s not gracious, so much as tactical. It was actually a strong move because Chris defended himself from a formidable, well-respected adversary competently. This actually makes him stronger. Going back to my first bullet about these #fintwit feuds…how many investment managers are not willing to expose themselves to the scrutiny? Live by the sword or avoid public battles altogether.
I should call attention to a wonky extension of this discussion. It’s the importance of the tail allocation living under the same umbrella as the risk-on investments to maximize the synergies of portfolio margining. This lessens the drag of the hedge and demonstrates why vol “solutions” often make more sense than stand-alone tail funds. It’s an adjacent discussion to why you want individual managers to run their strategies at as high a vol or leverage as possible subject to prudent margin management. This is more fee efficient. Too bad many professional investors don’t understand fee math. But this principle is also important because it means that vol is best managed at the portfolio level and not the individual manager level. If there is an investment that has an annual volatility of 40% and the equivalent fund running at 20% and they have the same fee structure you should pick the 40% vol version and allocate half as much. Notice how this incentive is the mirror opposite of an asset-gathering manager — they want to run maximum diversification to keep their vol low and the assets sticky.
[And if you really want to examine incentives, think about the PMs at the fund. The non-equity owners want maximum vol since their downside is just losing their job, but their upside is a percent of their performance. Their equity-owning counterparts want the assets to stick. Notice how the non-equity-owning PM has the same incentive as the LP, not the GP.
Comp structures, just like fee structures, are about shifting incentives to create alignment. But there’s a lot of haggling under the hood that looks an awful lot like options trading. When you negotiate comp, do you ever wonder who the patsy is? Or do you think you are in the ballpark of fair value AFTER considering all the levers/scenarios.]
