Shares of Apple could climb from current levels due to a couple of catalysts, UBS Managing Director Steve Milunovich said Tuesday.
"We're in a bit of an innovation lull," he said. "In terms of really exciting products, we're looking out to probably next year."
Apple stock declined 0.52 percent midday to trade at $400.56.
On CNBC's "Fast Money," Milunovich said that he expected the stock to head toward his $500 target within the next six to 12 months, when the company would start to get "some excitement back."

Shipments of the iPhone 5S would have to climb back toward 35 million to 40 million units in the next couple of quarters, he said, adding that low expectations had the company selling around 24 million iPhones in that period.
"Ironically, the big change in the phone is actually going to be the software in fall," Milunovich said, adding that the phone could boast digital-fingerprint security to enable mobile payments.
Apple could also introduce some kind of "pen" device, as well as a new iPad mini model that includes a Retina display.

"But is that really enough to get people excited and really boost those sales numbers? Probably not."
