Inside Billionaire Investor Carl Icahn

By Alexis Glick

Yesterday Carl Icahn made news by calling Yahoo’s board “irresponsible” for blowing off Microsoft’s $47.5 billion bid. Icahn spent $1.3 billion purchasing 59 million shares and has a 4.3% stake in the company and plans on seeking approval from the FTC to buy up to $2.5 billion in Yahoo stock. In his move to convince Yang and other board members to sell the company to Microsoft or face revolt, Icahn announced a new slate of directors to replace the current board.

This morning Mark Stevens, a friend of Icahn’s and author of “King Icahn, ” CEO of MSCO, Ron Geffner, a former SEC Enforcement Official and Hedge Fund expert and Teeka Tiwari of the Tycoon Report joined me to talk about Icahn’s motives, his past performance and why he actively looks to change the executives in corporations that he feels are underperforming. What motivates Carl Icahn? Are the companies that he invests in better for it? Take a look.
