The following video is from Thursday's edition of Investor Beat, in which host Chris Hill, and Motley Fool analysts Matt Koppenheffer and David Hanson, dissect the hardest-hitting investing stories of the day.

Billionaire investor Carl Icahn has increased his stake in Apple (NASDAQ:AAPL) by 22%, and has sent a letter to Apple CEO Tim Cook, continuing his push for a massive $150 billion stock buyback. Some have accused him of having purely short-term interests as the motivation behind the move. He however, says that this couldn't be further from the truth. In the lead segment on today's Investor Beat, Matt and David discuss the feasibility of the buyback, how beneficial it would really be for the company, and what our analysts think of Icahn's real motivations.
