Pete Najarian Sees Unusual Options Activity In Alibaba And STMicroelectronics

On CNBC's "Fast Money Halftime Report," Pete Najarian spoke about unusually high options activity in Alibaba Group Holding Ltd - ADR BABA and STMicroelectronics NV STM.

Traders were buying the August $250 calls in Alibaba on Tuesday. Around 7,500 contracts were traded and they paid around $12 for them. The trade breaks even at $262 or around 5.5% from the current stock price. Najarian decided to follow the trade.
