Wall Street Journal:

All you need to know about multibillionaire Carl Icahn is how he describes himself on his Twitter page: “Some people get rich studying artificial intelligence. Me, I make my money studying natural stupidity.”

He has purchased billions worth of Apple and eBay stock. But he’s not making a bet on these companies; he’s making a bet he can get these companies to do what he says.

He is smarter than the people who run them, you see, even though he has never produced much more than harassment and misery for most of his life.

Icahn’s moves are very obvious and easy to predict and understand.
