There is a flip side to that logic. VIX was in the upper range, at least upper quartile, on May 23 at 18.26. SPX promptly went up nearly 3% and has dropped 5% from that high, all within 3 weeks!Quote from IV_Trader:
why would option's pros short vols at the lower deciles in the first place? I really don't get it.
Sometimes high VIX is predictive of more volatility.
Of course now VIX is in upper decile, do we short premium now?
One method that could be employed is to sell premie at the VIX spike. If the market then rallies and VIX cools then buy premie back and go long vega.
Would have worked the last three weeks, but who knows what works next three weeks?
