Two experts break down whether to buy shares of Apple

Gene Munster, founder and managing partner at Loup Ventures, and Barton Crockett, Rosenblatt Securities senior analyst, join CNBC's 'Squawk Box' to discuss whether investors should buy shares of Apple after the iPhone maker sets a new product launch date. "I think you have a lot of hopeful things that won't materialize near term, and some fundamental questions that mean you don't have to own the stock today," Crockett tells CNBC.
