Obviously we already know the answer to that question.Quote from sle:
The question you want to answer is - "am i simply underwriting tail events or extracting some sort of excess value?"
The very few who can extract excess value would not post what they do, here or anywhere else.
Couldnât agree more, I would just emphasis that these people always, always over leverage and set their sites on annualized returns that no one in the history of the market has ever achieved in the long run. Additionally they almost never have the many years of trading experience necessary to understand how to handle things like the inevitable gap move, fast markets, and the deer in the headlights mentality of hoping it will come back. Hopefully their investors know enough to sue the âinvestment managerâ when the blowup happens.Quote from sle:
Well, best way of describing it would be "distributional arbitrage" so it combines both direction and volatility.
To be honest, my issue with these guys is not that these strategies are totally wrong, I do believe that there is alpha in selling wings. It's that they
(a) frequently do it as a mechanical system instead of actually evaluating the alpha in the trade
(b) frequently think that they have invented something that nobody had thought of before and thus they are golden geniuses
(c) do not pay much attention to risks and discount rare events
(d) and, most importantly, rather quickly try to become "asset managers" or "teaching gurus"
The combination of (b) and (d) is definitely the worst.
