Yes. When put skew is steep and vol is high (a somewhat rare combo but happens), buy 1 put strike, and sell 2 further out put strikes.
If vol is low and skew is flat (an even rarer situation), do the opposite, especially if you're bearish (bullish vol)....maybe even sell 1 and buy 3 for same IV levels.
Do you know of any website where it is possible to scan options or stocks and indexes according these combos of volatility and skew?
