Quote from chewbacca:
this sounds like BS
an option buyer has the RIGHT NOT THE OBLIGATION to take deliverily of the underlying on an ITM option at expiration..........so how the hell could he have gotten auto-delivery unless he notified his broker beforehand.......he is not obligated to take deliver of underlying.
If the calls are ITM at expiration they would be automatically exercised. Sounds like he got auto exercised at his strike price but Monday had to sell the stocks for a loss. Some good advice when trading a stock like GOOG on expiration Friday when its earnings are coming out is use the next month not the current for long plays like that.
