There is no way a retail investor can compete in this space against the quants & PhDs with billions of dollars in research and pricing models behind them.
Darn it, guess I've gotten lucky. (Again.) I should get Goldman Sachs on the line and tell them I have a lot of money I need to give back to them because I didn't fall in line with the quants or PhDs.
You make money almost every day for 10 years until volatility explodes and then you are bankrupt."
If you are in danger of going bankrupt in a vol expansion, you're trading wrong, or too large. Or, you shouldn't be trading at all.
Of course, a big market drop or a black-swan event will be vulnerable to drawdowns and losses as will any regular retail investor who thinks "buy and hold" is any less risky.
I've successfully managed volatility expansions (a VIX move from 12 to 50+ where liquidity dries up) and had no issues that even tickle into the realm of bankruptcy. (And I've traded the mini-crash and the last correction).
