Microsoft Stock Plummets over Terrible Earnings

Down close to 10 percent

Microsoft is having a bad day.

The company's stock was down more than 8% when the stock market opened Friday following a dismal earnings report, and declined by as much as nearly 10% in early morning trading. That is, Microsoft lost more than $25 billion from its market cap in a matter of hours.

Microsoft's fourth quarter earnings report disappointed by pretty much every metric: It missed on revenue and missed big on profits. Revenue for its Windows division declined by 6% year over year. And perhaps worst of all, Microsoft reported taking a $900 million charge related to its Surface RT tablets.
