Blackberry getting squeezed

SHARES OF Research In Motion fell more than 7% after a Morgan Stanley analyst said the BlackBerry maker would have to shrink considerably to survive.

That would erase much of RIM’s earnings power, the analyst said in a note to investors in which he downgraded RIM to “underweight” from “equal weight.” He had little faith next-generation BlackBerry 10 devices will reverse RIM’s decline.
