Activist investor and major Apple Inc shareholder Carl Icahn said the iPhone maker's stock should be trading at $216, far above its record high of $124.92 hit on Wednesday. At $216 per share, Apple - already the world's most valuable company - would be worth about $1.3 trillion, or about the size of South Korea's gross domestic product. The company is valued at just over $700 billion currently. Icahn said Apple should be trading at 20 times earnings per share, which taken together with net cash of $22 per share works out to $216 per share. http://www.reuters.com/article/2015/02/12/us-apple...
