In 2011, Goldman redeemed Buffet's investment at a 10% premium. At that time, Buffett revisited his warrants with Goldman Sachs and bought 13.2 million shares of the company. At that time, the company's stock was hovering around $163 per share. He sold the stock for a tidy profit in 2013. In all, Buffett made a profit of approximately $2 billion from his investments in Goldman.
One could argue that this amount was Buffett's compensation for taking an extraordinary risk during fraught times. But Buffett had thought through the extent of his risk-taking. As he put it in an interview: "If I didn't think the government was going to act (to pass the $700 billion bailout), I would not be doing anything this week. It would be a mistake buying anything right now."
