Facebook shares soared over 12% after the bell yesterday, when it easily topped Wall Street's most optimistic estimates and posted more than $1B in quarterly profit for the first time ever. For most of past year, Facebook's (NASDAQ:FB) spending outpaced its revenue growth, as it invested in projects such as virtual reality, artificial intelligence and delivering Internet access to remote areas, but in the latest quarter that dynamic reversed. "It's doom and gloom all around us and these guys are just killing it," said Kevin Landis, CEO of Firsthand Capital Management.
