Is Apple Really Worth $1 Trillion? Carl Icahn Thinks So, Some Have Their Doubts

Apple became the first American company to surpass $700 billion in market capitalization earlier this week. But apparently that wasn't enough. The next day, famed activist investor Carl Icahn issued a letter to his Twitter followers arguing the iPhone maker should actually be trading $90 higher than it is, at a price that would value Apple at more than $1.2 trillion. For that reason, he wrote, Apple should give investors their due by repurchasing more of its own shares.
