I am wondering what is wrong with selling VIX puts when VIX is at some super low level(ie. historically close to 10). It's very hard for it to go lower and in worst case we will get to pay our strike price(x100) on expiration. I know the premium is trash but assuming we would re-buy the option(close) at smallest VIX spike it's still going to generate some profit. Just what could go wrong? Poor liquidity of short term VIX puts preventing us from closing position to secure premium? Commissions?
