Blue Vertical lines are weekly Options Expiration (OPEX). Red are monthly OPEX. Yellow is Quarterly OPEX. Choosing the 'sane' high value for that month and taking it to the non-weekly opex date shows a pretty clear pattern of AAPL getting quite beat up on Fridays. Based on this pattern, and an average drop of %6.22 off of the high's, I'm throwing a SWAG of 445-ish closing price on Friday. Lots of retail investors betting on options, and Big Money (or MM's) will pin the price to make many call options expire worthless.
