Jim Simons, the legendary investor and founder of hedge fund Renaissance Technologies, gave a rare interview to Ted’s Chris Anderson to chat about his stint at the National Security Agency, his hedge fund and the role scientists can play in finance.
Simons spent time cracking codes at the National Security Agency early in his career, before later moving on to investing.
He explained that his hedge fund used some of the same skills he used at the NSA to get an early read on what to buy and sell in financial markets.
He said: “When I started doing trading, I had gotten a little tired of mathematics. I was in my late 30s, I had a little money. I started trading and it went very well. I made quite a lot of money with pure luck. I mean, I think it was pure luck. It certainly wasn’t mathematical modelling.
“But in looking at the data, after a while I realised: it looks like there’s some structure here. And I hired a few mathematicians, and we started making some models — just the kind of thing we did back at IDA [Institute for Defence Analyses]. You design an algorithm, you test it out on a computer. Does it work? Doesn’t it work? And so on.”
Simons $US22 billion hedge fund is known for bringing in mathematicians, astronomers and physicists into the trading world.
Simons explained: “I didn’t really know how to hire people to do fundamental trading. I had hired a few, some made money some didn’t make money.
“But I did know how to hire scientists because I have some taste in that department. So, that’s what we did. And gradually these models got better and better, and better and better.”
