It's not just being long vol - when the stock market panics, dynamics of vol become a lot easier to predict, and you can make a _lot_ of money intraday, being short or long as the situation warrants. This however requires your market price fitting setup (vol surfaces etc) to be very robust, to not be broken by the market dislocations, otherwise you'll lose more money than you make, because of acting on bad price feeds. (Yes, I'm working in a group that does that kind of trading). Unfortunately, by the time all the johny-come-latelies that are building a team now get to market, they'll probably be crowding each other so much that it'll be hard for them to make money - and the older groups will probably switch to making money off _them_ .
