Long, but a good read on Jim Simons, the founder and to-date still biggest shareholder of what's now the largest and also one of the consistently most profitable hedge fund's out there, the quant driven Renaissance family of funds.
Some excerpts:
"Bloomberg
...Renaissance's assets have more than doubled in a year from about $16 billion on Sept. 30, 2006. That growth has catapulted Renaissance past such titans as Daniel Och's Och-Ziff Capital Management Group LLC, Ray Dalio's Bridgewater Associates Inc. and David Shaw's D.E. Shaw & Co. to become the world's largest hedge fund manager, according to data compiled by Hedge Fund Research Inc. and Bloomberg.
In quant funds, mathematicians and computer scientists mine enormous amounts of data from financial markets looking for correlations among stocks, bonds, derivatives and other instruments. They search for predictive signals that will foretell whether, say, a palladium futures contract is likely to rise or fall.
...Simons, standing just under 5 feet 10 inches tall and weighing 185 pounds (84 kilograms), has trod an unlikely path. A former code cracker for the U.S. National Security Agency, in 1968 he became chairman of the mathematics department at Stony Brook University, part of the New York state university system. He built the department into what David Eisenbud, former director of the Mathematical Sciences Research Institute in Berkeley, California, calls one of the world's top centers for geometry.
...Simons dabbled again in commodities while at Stony Brook. The Colombian factory investment had made some profit. Simons and his partners invested about $600,000 of it with Charles Freifeld, a former math student of his from Harvard. During seven months in 1974, Freifeld increased the investment 10-fold, after fees, as sugar futures more than doubled. The $600,000 was now $6 million, Freifeld says.
...Leaving Academia
In 1977, frustrated with a math problem and eager for change, he abandoned academia to start what would become Renaissance, hiring professors, code breakers and statistically minded scientists and engineers who'd worked in astrophysics, language recognition theory and computer programming.
Simons left Stony Brook in 1977 and started Monemetrics, a predecessor to Renaissance, in a strip mall across from the Setauket train station. He wanted someone to trade currencies and commodities and turned to an old friend, a fellow code cracker from the IDA: Leonard Baum.
Baum was co-author of the Baum-Welch algorithm, which is used to determine probabilities in, among other things, biology, automated speech recognition and statistical computing. Simons's idea was to harness the mathematical models that Baum was writing to trade currencies.
``Once I got Lenny involved, I could see the possibilities of building models,'' Simons says.
Baum never traded using the models. In the late '70s and early '80s, Baum was making too much money on fundamental trading. Such trading involves betting based on, say, whether British Prime Minister Margaret Thatcher would let the pound rise. In an era of one-way markets, it was much easier than using models.
``The dollar was very weak; all you had to do was short the dollar and you'd make a lot of money,'' Simons says.
`Magic or Nonsense'
Simons brought in Ax to look over Baum's efforts. Ax declared that not only would the models work with the currencies Baum had written them for, they could be applied to any commodity future --wheat, crude oil, you name it, Simons says.
During the 1980s, Ax and his researchers improved on Baum's models and used them to explore correlations from which they could profit. If a futures contract opened sharply higher versus its previous close, they would short it; if it opened sharply lower, they would buy it, says Sandor Straus, a former manager for Medallion who now runs his own investment firm, Merfin LLC, in Walnut Creek, California.
The stuff wasn't complicated, and it worked.
Medallion stopped taking new money from outside investors in 1993 and returned pretty much the last of their capital 12 years later. Today, the fund is run almost exclusively for the benefit of Renaissance staff.
Though Simons dislikes talking about it, Renaissance has built him a tidy fortune. U.S. Securities and Exchange Commission documents show he controls 25-50 percent of Renaissance, having spread the rest of the firm's ownership among employees. So Simons's share of the performance fees earned by RIEF and Medallion was roughly between $375 million and $750 million in 2006, according to data compiled by Bloomberg.
With Medallion's 44.3 percent return in 2006, if Simons had invested $2 billion in the fund, he would have garnered an $885 million profit. He declines to comment on his investment.
With his myriad positions in different markets, Simons likens his approach to the extensive farming he once practiced in Colorado, using center pivot irrigation to grow wheat on thousands of acres.
``Every little stalk of wheat was not doing so great, but most of them were, so you're working on statistics,'' Simons says.
By contrast, he says, the traditional focused investing practiced by Warren Buffett is akin to intensive farming, in which each individual plant really counts. ``It's two completely different ends of the spectrum,'' Simons says."...
