KEY POINTS
  • Apple's new iPhone 8 hits store shelves on Friday, and Gene Munster says people are "going to see a lot shorter lines than last year."
  • "The reason is that this cycle is split between two phones ... [and] more people are buying things online," he says.

Apple investors should expect a "rocky day" as the tech giant's iPhone 8 and iPhone 8 Plus hit store shelves, leading analyst-turned-venture capitalist Gene Munster told CNBC on Friday.

Shares of Apple, which were under pressure again Friday, were down more than 5 percent for the week after some speculated that demand for the new iPhone 8 was weak. Apple also faced lackluster reviews for the phone.
