Quote from tradermike79:
Yes, years of heavy gains during expiration week. What you said makes sense, however after going short every expiration day, and week, for over four years, I will say that options are often too expensive during expiration week. Especially the OTMs. So, my conclusion is that options are seldom priced fairly and many times over priced on expiration day (especially near the close). You just have to look for those fat tails or people trying to dump their shorts while rolling them into next month etc...
Options are too expensive based on what facts? Incidentally history has shown that options are fairly priced expiration week and day.
