Quote from sle:
I would say that's not the wisest trade out there - you are selling puts on an asset with a positively-sloped term structure and thus you will have a pretty strong negative drift. While I agree, vol of vol is high and selling it looks attractive, I would be very reluctant to sell puts with a strike that's more or less equal to the ATM spot level.
That's why I hate selling equity/index options. You have to sell close to ATM to get any reasonable premium. That's why I sell futures options.
