Carl Icahn, Activist Investor, Faces Intense Scrutiny From Wall Street

Chief executives of public companies have long feared Carl C. Icahn. The 88-year-old investor made a name and billions for himself by questioning the decisions and strategies of corporate leaders and agitating for change at companies like Apple, RJR Nabisco and Netflix.

But now Mr. Icahn is under intense scrutiny from Wall Street investors, who are rapidly selling his company’s stock. In the past year and a half, shares of Icahn Enterprises, his publicly traded investment company, have dropped more than 75 percent, losing nearly $20 billion of value. After dropping more than 30 percent since mid-August alone, it now trades at $10.53 a share, its lowest level in more than two decades.

Mr. Icahn owns roughly 86 percent of the shares, so he has personally lost about $17 billion.

“There’s a confidence game and he’s lost the confidence of investors,” said Don Bilson, who focuses on activist investing as the head of event-driven research at Gordon Haskett Research Advisors.

Some Wall Street investors are now worried that the stock’s continuing fall could threaten the health of the entire company and that it could be forced to sell companies it holds. Icahn Enterprises holds a mix of public stocks, real estate and other investments, according to interviews with Mr. Bilson and several other market watchers.
