Call Buyer in RIMM

Research In Motion Limited

, the beleagured maker of the Blackberry mobile phone, sees a multi-exchange sweep of 10,000 August 8 calls on Thursday afternoon with all of the contracts trading on the offers of $0.13. Total volume in this strike has surpassed 14,700 on the day and has helped push the put/call ratio down to .33. Today's option activity looks as if at least one investor believes the shares are due for a short term bounce after setting a new 52 week low of $6.56 last Monday. With just 3 weeks left until these contracts expire, these options will need the shares to rally at least 15.5% from their current level to begin to show any profits.
