Apple becoming a one-trick pony: Pro

Long-term Apple skeptic: Pro

Apple stock is soaring but at least one pro thinks the tech giant's ride will come to an end in 2015

"It's losing market share like crazy. It's becoming a one-trick pony … it is a phone company," Bert Dohmen, president of Dohmen Capital Research said.

That said, he told CNBC's "Closing Bell" he is bullish for the short term—but only because of "financial engineering" by the company in the form of stock buybacks.

"I'm bullish for the stock into year end. It should be strong because this is when most of the stock buybacks are done by companies," Dohmen explained.

However, those buybacks can't mask the fact iPad and iPhone sales are down, he said.

Timothy Lesko, principal at Granite Investment Advisors, disagrees. He likes the stock and sees nothing wrong with stock buybacks or the company's future.

"Apple is selling more devices now than it did last year and they are selling them at margins that have held up," he said.

"They may be losing low-end market share in cell phones, but they own the high end."

Plus, Lesko likes that the company is trading at 13.5 times earnings.

"The story's intact, the company's returning cash to shareholders and the valuation is where you want it."
