Hedge fund billionaire Carl Icahn took a "large" position in Apple Inc. (AAPL.O) shares and told Reuters on Tuesday that he believes Apple should trade at $700 a share. In a telephone interview, Icahn said he believes "Apple has the ability to do a $150 billion buyback now by borrowing funds at 3 percent. "If Apple does this now and earnings increase at only 10 percent, the stock - even keeping the same multiple currently - should trade at $700 a share." http://www.reuters.com/article/2013/08/13/us-funds-icahn-apple-idUSBRE97C0XK20130813 Do you think it reasonable opinion?
