To answer you question:
I'm not buying premium just because it's cheap. Nor am i selling premium just because it's expensive.
Depends on the trade I'm considering. There are plenty of deals I evaluate on a daily basis that have very good premiums, but upon examining the stocks, I end up deciding I'm not going anywhere near those stocks.
The only thing cheap premium says to me is,.... if I were long stocks, it's cheap to buy insurance for them.
But I'm not getting in or out of the market just because premium is cheap or expensive.
As for whether i consider implied vs historical IV..... NO.
Unless you go back and review what the market was doing when the historical was high or low, or what the specific news surrounding the stock and/or sector was 1 - 2 years ago, and so on, then what's the point?
If you are just comparing numbers, but not CONTEXT,.... then you are not a thoughtful investor. You are a lazy simplistic investor.
I deal with the option market, based on the reality that it currently is. Not the fantasy I wish it to be.
If a stock I'm considering meets my fundamental and technical criteria, as well as the minimum annualized % return I would normally accept, for the strike and % otm safety cushion I desire,.... then I'm going to invest in it, regardless of what the VIX is and regardless of what the IV is compared to its historic.
I would LOVE if the VIX were back in the 20's, 30's or 40's before investing.
But again, I deal with the market as it is, not the fantasy I desire.
If the VIX and IV are too low to offer the strikes, credits and otm cushions I desire, then I simply don't do that specific deal until it does. But I'm not getting out of the market if there are still trades that do meet my criteria.
