Quote from trefoil:
I've been fooling around, both with the SPY and with IWM, with using the vol indices - respectively the VIX and the RVX - to give signals on these guys far as when to buy puts or calls. Just started, so not a lot of results yet, except for backtesting, but the backtesting came up with decent results, once you figure out how to "predict" where the vol indices are going, and so far real life is working out OK too.
I'll have a better idea on this in a few months.
