Navistar International Corp. (NYSE:NAV)
Shares of this truck maker have come up 20.3 percent since the beginning of 2013, and Icahn owns over 10 million shares.
Icahn’s involvement in Navistar is of the “activist” nature. The man has called the company a “poster child for abysmal business decisions and poor corporate governance” — Harsh language, but backed up by a 59.2 percent decline in the company’s stock price over the past two years, punctuated by top- and bottom-line contraction in 2012. Navistar recently granted two board positions to allies of Icahn, who have arguably begun the process of helping turn the company around.
