During the credit crisis John Paulson made a huge hedge fund fortune betting against mortgage-backed securities in what has become known as the greatest trade ever. After posting huge returns in 2007, investors flooded Paulson’s hedge funds with massive amounts of new money, which he gladly accepted.

That may have been his mistake. By the end of 2008 Paulson’s hedge fund firm was managing $36 billion and it has become clear that managing all that money has been a very difficult thing for him to do.
