Activist investor Carl Icahn said Apple Inc.’s stock should be trading at $216, far above its record high of $124.92 hit on Wednesday. At $216 per share, Apple would be valued at about $1.3 trillion, compared with about $700 billion currently. Icahn said Apple’s price-to-earnings ratio should be about 20 times, which taken together with net cash of $22 per share works out to $216 per share. “Also, to the extent Apple introduces a TV in FY 2016 or FY 2017, we believe this 20X multiple is conservative,” the billionaire Apple shareholder wrote in a letter to his Twitter followers. Icahn owns about 53 million Apple shares worth $6.5 billion. Apple shares were up 2.3 per cent at $124.86 in afternoon trading on the Nasdaq.
