Jon Najarian Sees Unusual Options Activity In BlackBerry And Pure Storage

On CNBC's "Fast Money Halftime Report," Jon Najarian spoke about unusually high options activity in BlackBerry Ltd BB. He said there are rumors an activist might be involved with the stock, so options traders are aggressively buying calls in the name.

They bought around 10,000 contracts of the June 8.50 calls on Tuesday and they added around 28,000 contracts on Wednesday. Najarian bought the calls and he is planning to hold them for a week.
