"You have to look at the 100-day moving average," he said, which sits at 1,828. "If this gets lengthier than five days below 1,828, then the market is in trouble."

Grasso also offered a name he would buy on the dips. "With more access to cars, Pandora's going to be in more and more rides going forward. I think this is a good place to buy it," he said.

Jon Najarian of said that the market weakness presents a great entry point for online travel company Tripadvisor, which fell 8 percent in just the past week. "Right now, with it down as much as it is, I would be a buyer of TRIP," he said.
