do i care how many expired worthless? isn't he asking the wrong question? he says roughly 75% expired worthless, so what? if I write 5 options strikes for avg $1 premium per strike . . . 4 expire worthless and one expires 6 dollars in the money, am I crowing that i was right on 75% of my writes? his study needs to look at some weighted average expiration intrinsic vs premium value
was thinking the same thing. there is also a maximum return that one can gain via selling an option vs the potentially unlimited return you can gain via buying an option.
