Another day, another reasonably optimistic projection for BlackBerry (BBRY). Per Bloomberg, Morgan Stanley analyst Ehud Gelblum has more than doubled his price target on BlackBerry shares from $10 to $22 and is now projecting that the company’s profits will “meaningfully” increase as loyal BlackBerry 7 users rush to upgrade to BlackBerry 10 over the next two quarters. The downside, however, is that Gelblum thinks that this boost could be short-lived and that there’s still a low probability that BlackBerry will emerge as a “viable” third mobile operating system alongside Android and iOS. All the same, getting a short-term boost that helps you live to fight another day is better than outright crashing and burning as some other industry watchers have suggested, so this analysis is still welcome news for BlackBerry.
