Owing to the sheer number of stocks that are listed for public trading and the thousands of transactions that take place on the market daily, mathematics is a fundamental part of today's stock market. Analyzing trends and share behavior enables the prudent investor to decipher underlying trends that can be exploited for trading.

Formally, these trading strategies are dubbed quantitative trading, and they have produced one of the most successful hedge fund bosses of our time, Jim Simons of Renaissance Technologies. His hedge fund is one of the largest in the world, and according to Insider Monkey's research, its investment portfolio was worth a cool $69.3 billion as of Q2 2023 end. While he does not oversee daily operations at Renaissance these days, his journey in the investment world has made Mr. Simons one of the richest people in the world. We took a look at his net worth as part of our coverage of 20 Highest Paid Hedge Fund Managers of All Time to discover that Jim Simons is the third richest hedge fund investor of all time with his investment career yielding him $28.1 billion in fortune.

While the 85 year old Jim Simons doesn't run a hedge fund anymore, as his health would undoubtedly thank him, the decades of experience that he has gained in the finance industry makes him nothing short of a legend. He is also one of the few hedge fund bosses to have a background with the intelligence services, courtesy of Jim Simons' stint with the National Security Agency (NSA) in 1964. He set up Renaissance Technologies in 1982, and six years later, Mr. Simons would set up one of the world's best known investment portfolios, the Medallion Fund. Medallion is a pure play mathematical fund, and its early days sought to leverage mathematical values known as correlations to profit from the stock market. Renaissance Technologies stopped using external capital for the Medallion Fund in 1993, and now, it is available only to existing or former fund employees.

Amassing a $28.1 billion fortune is no easy tasks, and neither is setting up a fund that delivers 39% post fee annualized returns for three decades. So naturally, a deeper look at Renaissance and Jim Simons' secret sauce is merited. Unfortunately, the quantitative black magic behind the firm's success is a closely guarded secret, but we can learn a couple of things about RenTec's business culture based on its hiring decisions. As opposed to most other hedge funds and banks that rely on finance graduates to manage money, Mr. Simons' hedge fund is one of the few in the world that also brings in mathematicians and scientists in its fold. What do they have in common? Well, the sciences depend on a 'scientific approach' towards research and decision making, meaning that the thought process at Renaissance Technologies is based purely on evidence based, mathematical thinking.
