There’s a reason people pay so much attention to Carl Icahn — the corporate raider/activist investor, depending on how you want to characterize him. It’s because he knows what he’s doing.

On Wednesday morning, Icahn tweeted out that he’d closed his position in Netflix, that is, sold off the last of his stock.

He bought 10 percent of the company three years ago at $58 a share; it topped $700 a pop this morning.

Icahn walked away with $993 million from Wednesday’s sale, but is estimated to have earned about $2 billion total over the past three years from his investment in Netflix
