What: Shares of BlackBerry maker Research In Motion (NYSE:BB) have skyrocketed by as much as 14% today on analyst optimism regarding its next-generation BlackBerry 10 operating system.

So what: The U.S. market was closed on Thursday, but yesterday National Bank analyst Kris Thompson increased his price target from $12 to $15 while reiterating his outperform rating. Thompson notes that there is "positive sentiment building in the industry" ahead of BB10's launch next January. The analyst also expressed confidence in management's ability to execute.

Now what: RIM's leadership is maintaining the company's BlackBerry subscriber base, cutting costs and preserving cash, and preparing for a global rollout of BB10 devices. This is the second time within the past week that analysts have given RIM bulls some fuel, as Jefferies analyst Peter Misek recently laid out a possible case for a $43 price target if BB10 is a smashing success. Shares rallied on the comments in Canadian markets on Thursday, and today's jump is allowing it to catch up stateside.
