Pete Najarian bought shares of Apple for his Halftime Report Portfolio on the belief that the Apple Watch and new iPhones this year will drive the shares higher.

Najarian made the trade live on CNBC's Halftime Report after host Scott Wapner complained that he hadn't made one move all quarter for the contest.

"I've owned Apple personally for a decade," said Najarian. "Everyone talks about valuation, but it's not that. It's the next catalyst."
