'Fast Money' Traders: Wait For Pullback On Roku

On CNBC's "Fast Money," Steve Grasso spoke about Roku Inc. ROKU, which traded sharply higher on Friday, on better than expected earnings. Grasso said Roku checks back to its 50-day moving average habitually and that its 50-day moving average is currently around 20% lower than what the stock is trading at. With a rising 50-day moving average, Roku is "due for a 15% check back," Grasso said. He would wait and buy the stock on the pullback.

Pete Najarian said Roku had an unbelievable quarter, but he likes Grasso's idea to wait for a pullback. He thinks there might be a better opportunity to buy.
