While the sales of Apple’s iPhone 5 fell short of the most optimistic estimates, Brian Marshall of ISI Group said Monday on CNBC that the company’s potential growth was still “100 percent greater.”

Marshall estimated that there were still “a couple of million units in transit,” based upon the pre-orders of the iPhone 5. “They’ve sold a lot more than 5 million,” he said on “Fast Money.” “We think the story’s intact for sure.”
