Just after noon yesterday OptionMonster's systems lit up with several large blocks of the July 17.50 calls bought for $0.50, followed by one enormous print of 18,000 purchased for $0.55 just minutes later. More than 39,000 calls changed hands by the end of the day at that strike, more than four times open interest and dwarfing the average call volume of 730.
BJ Services ended the regular session up slightly to $15.58 on heavy volume and rose another 1.41 percent in after-hours trading. The shares would need to rise another 16 percent or so by July expiration for yesterday's trades to make a profit.
