In an excerpt from his new book, Michael Lewis profiles Michael Burry, who shorted housing in a big way:
Right from the start, Scion Capital was madly, almost comically successful. In his first full year, 2001, the S&P 500 fell 11.88 percent. Scion was up 55 percent. The next year, the S&P 500 fell again, by 22.1 percent, and yet Scion was up again: 16 percent. The next year, 2003, the stock market finally turned around and rose 28.69 percent, but Mike Burry beat it againhis investments rose by 50 percent. By the end of 2004, Mike Burry was managing $600 million and turning money away. “If he’d run his fund to maximize the amount he had under management, he’d have been running many, many billions of dollars,” says a New York hedge-fund manager who watched Burry’s performance with growing incredulity. “He designed Scion so it was bad for business but good for investing.”
Burry found out that he has Aspergers at the age of 35:
Thus when Mike Burry went into business he disapproved of the typical hedge-fund manager’s deal. Taking 2 percent of assets off the top, as most did, meant the hedge-fund manager got paid simply for amassing vast amounts of other people’s money. Scion Capital charged investors only its actual expenseswhich typically ran well below 1 percent of the assets. To make the first nickel for himself, he had to make investors’ money grow. “Think about the genesis of Scion,” says one of his early investors. “The guy has no money and he chooses to forgo a fee that any other hedge fund takes for granted. It was unheard of.”
[The diagnosis] explained an awful lot about what he did for a living, and how he did it: his obsessive acquisition of hard facts, his insistence on logic, his ability to plow quickly through reams of tedious financial statements. People with Asperger's couldn't control what they were interested in. It was a stroke of luck that his special interest was financial markets and not, say, collecting lawn-mower catalogues. When he thought of it that way, he realized that complex modern financial markets were as good as designed to reward a person with Asperger's who took an interest in them. "Only someone who has Asperger's would read a subprime-mortgage-bond prospectus," he said.
