Motorola stock

Here's one to watch today, folks. Shares of Motorola Mobility Holdings Inc. (MMI) were up more than 50 percent at the start of trading Monday on the news that Google was acquiring it for $40 per share. Makes sense -- Google's gonna buy it at that price, and that's about where it's trading at now. But that's a hell of a jump for any stock, eh?
