it amazes me how many people have been jumping on the OP saying that options are always priced fairly. especially during expiration week. have you people actually ever traded or have you just read books about options? there is no "fair value" like everybody like to believe when comparing trade prices vs "theo". I've seen half the decay come out on the first 20 mins after the open, i've seen vols explode in that same time frame. taking on risk and being able to manage it is where you make money. key is managing your position. those front month options will have no vol very shortly. i don't care if you are long or short them.
