Two financial analysts have raised their targets for Apple stock. The highest target comes from Canaccord Genuity's Michael Walkley, who has pushed his forecast up to $655. "Our monthly channel checks indicated very strong sales trends for the iPhone 4S at all three U.S. carriers and overall strong iPhone sales in international markets. We are increasing our March quarter iPhone estimates from 30.1 million to 32.6 million units," he elaborates. Walkley's 2012 EPS prediction is being raised from $41.06 to $42.81.
