The cover story of the May edition of the Bloomberg Markets magazine discusses Nassim Nicholas Taleb’s affect on Wall Street:

On a freezing day in March 2007, Nassim Taleb walked into a conference room at Morgan Stanley’s Manhattan offices on 47th Street and Broadway to address a group of the firm’s risk managers. His message: Your models don’t work.

Using a whiteboard to scribble out his calculations, Taleb, now 48, began one of his rants, this time against stress tests–Wall Street lingo for examining how a market rout will play out. Stress tests are inherently risky because they ignore rare but potentially devastating events, Taleb said.

It’s always interesting to see what other investors or thinkers have on their bookshelf. In the introduction to the article, there’s a picture of Nassim Taleb in his library. Using the hard copy, I picked out a few books that Taleb has read (or hasn’t read, by Umberto Eco standards). These should be useful for expanding one’s network of mental models:

• Darwin’s Dangerous Idea, by Daniel Dennett
• Collapse, by Jared Diamond
• Guns, Germs and Steel, by Jared Diamond
• The Selfish Gene, by Richard Dawkins
• Rational Herds, by Christophe Chamley
• The Perception of Risk, by Paul Slovic
• Knowledge and Decisions, by Thomas Sowell
• Serendipity, by Royston Roberts
• The Construction of Preference, by Sarah Lichtenstein and Paul Slovic
• Evolutionary Dynamics, by Martin Nowak
• The Quark and the Jaguar, by Murray Gell-Mann
• Why Beauty is Truth, by Ian Stewart
• The Eastern Origins of Western Civilization, by John Hobson
• For and Against Method, by Imre Lakatos and Paul Feyerabend
• Probability via Expectation, by Peter Whittle
• Probability Theory, by E. T. Jaynes

Studying Students’ Reaction to Chance

An interesting article on a contest held at University of Virginia’s Darden School of Business. The contest split 269 students into two groups:

1. The first chooses one of two unmarked briefcases. One has a check for $18,750, and the other has nothing. Before opening the case, they are offered a chance to receive a fixed amount of cash in its place. It’s their choice.

2. The second group is given the cash upfront, and then offered the chance to buy one of the briefcases. For the student mentioned in the article, he was given $3,000. He could have walked away with the $3k, or bought the right to choose one of the cases.

The research showed that “buyers” (the second group) were more likely to keep the cash. Of course that isn’t rational, because the expected value of the case selection is $9,375 (a 50% chance of getting the $18,750 check).

The students admitted the decision is easier on paper, and more difficult when you have a handful of cash.

Overall, I’m glad Darden is doing research like this and teaching the students about decision making in the face of uncertainty. More schools should be doing the same.

Victor Niederhoffer is a well-known hedge fund manager who got his start managing a trading firm in the 1980s. From 1982-1990, he partnered with George Soros and ran the Fixed Income and Forex divisions of Soros’ firm. Niederhoffer has published two books: The Education of a Speculator (1996) and Practical Speculation (2003). Since 2001 he has run Manchester Trading LLC, which manages three small funds with total assets under management of about $350 million at the end of June. Manchester’s main fund had returned 50% annualized through the end of 2006, earning it a prize for best performance by a Commodity Trading Adviser².

Despite the level of respect for him in the trading world, Niederhoffer is most well known for the blow-up of his hedge fund in 1997. After the Asian financial crisis and a 7% one-day drop in the Dow, Niederhoffer Investments lost a majority of its capital and was forced to close down. These losses wiped out virtually all of the gains the fund achieved racking up 35% annualized returns since inception.
