BlackBerry stock has gotten a nice pop recently following the release of its first BlackBerry 10 device, but the company has a narrow window of opportunity, Matthew Hoffman, managing director at Cowen & Co., told CNBC's "Squawk Box " on Tuesday.
The reason, he said, is that new devices from and Apple are set to arrive in the coming months.
Shares of BlackBerry—formerly Research in Motion—are up 27 percent so far this year, but Hoffman said that's the best investors are going to see for awhile. Since its 2007 all-time high of more than $230, the company's shares have lost 93 percent of their value.
