Time Warner (TWX) investors face a "win-win" scenario with the antitrust trial for AT&T's (T) proposed takeover now under way in Washington, Andrew Bary of Barron's writes.

Time Warner shares "look appealing, based on their underlying value and AT&T's strong chances of winning," Bary contends. He notes the stock closed Friday roughly $11 below the current value of AT&T's cash and stock bid, worth $103.60 per share.

The 12% deal spread is appealing with "many observers" believing AT&T and Time Warner will prevail over the U.S. government, according to Bary. He adds that while Time Warner shares could fall $5 if the government wins, some analysts think the stock will quickly recover to its current price of $92.57.
