Jon Najarian Sees Unusual Options Activity In Roku And AGQ

On CNBC's "Fast Money Halftime Report," Jon Najarian spoke about unusually high options activity in Roku Inc ROKU and ProShares Ultra Silver AGQ.

There was a very short-term options activity in Roku as options traders were buying the Sept. 6 expiry, $155 strike calls. Najarian bought these calls and he is probably going to be in the trade for three days.
