Icahn Raises Apple Stake to $3 Billion in Buyback Push

Billionaire investor Carl Icahn boosted his stake in Apple Inc. to $3 billion, adding to one of his biggest holdings as he continues to push the iPhone maker to buy back more stock.

Icahn said he purchased $500 million worth of shares in the past two weeks, in one of three Twitter Inc. messages today. He called the additional investment a “no brainer” and said an in-depth letter is coming soon on the company’s need to repurchase more shares.
