Even thought the lock up date was Nov 14th,shares will not be available to sell until Monday the 19th. That would explain why we have not seen any selling execpt for owners that the lock up started on OCT 29th. Makes sense to me for the big guys to buy calls last week when FB was down,run it up to cash out at expiration today. Then buy Dec puts and let it crash when those lock up shares finally come to market. Brillant move!
