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. Recently, his attention shifted toward the booming online gaming industry after he reviewed a detailed list of social casinos, seeing potential to leverage these platforms and encourage these corporations to explore new, profitable digital avenues.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.
