About Jim Simons

James Harris Simons (April 25, 1938 – May 10, 2024) was an American mathematician and hedge fund manager. He founded Renaissance Technologies in 1982, which became one of the most successful and secretive quantitative hedge funds in history. Before entering finance, Simons was a renowned mathematician who contributed to the development of string theory and won the Oswald Veblen Prize in Geometry in 1976. He served as a codebreaker for the NSA during the Cold War and chaired the mathematics department at Stony Brook University. Renaissance's flagship Medallion Fund is considered the most successful hedge fund ever, generating average annual returns of about 66% before fees (39% after fees) from 1988 to 2018. The fund uses mathematical models and algorithms to identify market inefficiencies and execute trades. Simons pioneered the use of quantitative and algorithmic trading strategies, hiring mathematicians, physicists, and computer scientists rather than traditional Wall Street traders. His approach proved that rigorous mathematical analysis and data science could consistently outperform traditional investment methods. He donated billions to scientific research and education through the Simons Foundation, particularly supporting mathematics, physics, and autism research.
