Reuters reports that Electronic Arts stock is up on the day based on rumors that Microsoft is planning a takeover bid. They hash through the possibilities with some analysts, and seem to believe it's not happening:

"There's talk that Microsoft might be interested in acquiring Electronic Arts. It's unsubstantiated chatter, but it's out there," said Frederic Ruffy, an options strategist at WhatsTrading.com in New York.

But Trip Chowdhry, an analyst at Global Equities Research, said Electronic Arts was not on Microsoft's "radar screen" based on his industry contacts.

"Our contacts just don't see Microsoft buying Electronic Arts, no synergies whatsoever, and also not Microsoft's corporate primary focus right now," Chowdhry wrote in an e-mailed note.
