The short interest in some major technology stocks has increased sharply in recent weeks. The short sellers' view may make sense since these companies have helped drive the NASDAQ recovery.
Activision Blizzard posted better-than-expected fourth-quarter results thanks to strong holiday sales of Call of Duty: Modern Warfare 2 -- last year's best-selling video-game title. The company also initiated a dividend and announced a $1 billion share repurchase program.
Take-Two Interactive, publisher of popular video games such as Grand Theft Auto, announced disappointing earnings Thursday. But that didn't deter Carl Icahn from buying an 11 percent stake in the company the same day.
