The May 8 call has an open interest over 34000 which is almost 5 times greater than its other strike prices. Stock down .50 from its high today so far. Writers must hate to see the stock take off over 8 with that number of calls out. I've even got a few.
The July 10 is also way larger than other strikes, so I wouldn't be surprised to see the cappers try to keep it below 10 at least through July expiration. Could be quite a fight.
