Charter is said to be weighing whether trying to top Comcast's bid for Time Warner Cable is worth the risk of potentially losing out on the opportunity to capture the 3 million customers Comcast plans to divest. "It's a real game theory situation that's tough to address," said Wunderlich Securities analyst Matthew Harrigan. "Comcast probably doesn't want to go higher on the price for Time Warner Cable. ... But that affects Charter too. So I think Charter's in a bit of a box."
