Besides increasing his stake in Apple Inc. (NASDAQ:AAPL), Icahn disclosed a new stake in the online auction company eBay Inc (NASDAQ:EBAY). As of March 31, he owned 27.8 million shares of the company. Notably, Icahn had been putting pressure on eBay to spin off its payments arm PayPal. But eBay announced last month that it has worked out a deal with the billionaire investor to end his effort for spinning off PayPal. Carl Icahn also withdrew support for two people he had nominated for the San Jose-based company's board.
