Carl Icahn said he hasn't sold an Apple (NASDAQ: AAPL) shares, Bloomberg's Trish Regan reported on Twitter today after talking with the billionaire hedge fund manager ahead of today's iPhone event. In fact, he is adding to his position.

"Where else can you get a growth company at 10x earnings?," he tells Regan. "While everyone is worried about the new products today, I just look at the math," he was also quoted as saying. "Numbers speak for themselves."

Today's news comes amid rumors in the market that a Mr. Icahn sell-program led to the September 3th 4% sell-off in the stock. It has been about one year since Icahn first disclosed his stake in Apple and he is up about 50%.

Icahn is famous for calling buying Apple a "no brainer," although he dropped his plan for a massive Apple buyback proposal in February.
