We currently have a large position in APPLE. We believe the company to be extremely undervalued. Spoke to Tim Cook today. More to come. — Carl Icahn (@Carl_C_Icahn) August 13, 2013

Billionaire investor, who gained increasing fame in recent months due to his attempted take over of Dell, has announced via Twitter that his firm has taken a “large position” in Apple:

Had a nice conversation with Tim Cook today. Discussed my opinion that a larger buyback should be done now. We plan to speak again shortly. — Carl Icahn (@Carl_C_Icahn) August 13, 2013

Icahn further added that he had a “nice conversation” today with Apple CEO Tim Cook. Icahn suggested even larger buy-back plans for Apple. Earlier this year, Apple launched a major multi-billion-dollar stock buy-back program.

Responding to the news, AAPL investors helped the stock sore to a new 6 month high of over $488 per share. Apple has also responded to the news:

We appreciate the interest and investment of all our shareholders. Tim had a very positive conversation with Mr. Icahn today.
