Quote from newwurldmn:
Actually that edge went away like 7 years ago.
Equity index options are still systematically overpriced, though, even if somewhat less so than earlier (leaving aside for a moment whether more so than individual stocks). Would you agree with that?
Some of the research along the lines you cite has been questioned. See e.g. http://www.donfishback.com/blog/201...orresponding-etf-options-what-does-don-think/ ,
I do not know for sure who is right on that, but in any case, for credit strategies, it seems to me that most traders who are selling premium favor selling index options over individual stocks premium for other reasons as well. The distribution is going to have much more extreme tails for individual stocks because of takeovers, earnings surprises, etc.
Now over a broad enough portfolio, that might be manageable.
In any case, most are probably going to apply additionally trade selection and timing to their trades, so that the systematic results are not necessarily determining. There will be good times to buy and to sell individual stock options and to buy and sell index options, and they will differ.
