Summary
Jim Simons, the mathematician and quantitative hedge fund manager known as the "quant king," has died at age 86, according to a statement from his family foundation. Simons Foundation president David Spergel said on Friday that "Jim was an exceptional leader who did transformative work in mathematics and developed a world-leading investment company," as reported by the Financial Times.
Simons, born in Massachusetts in 1938, earned an undergraduate degree from MIT in 1958 and a doctorate from the University of California, Berkeley in 1961. He worked as a Cold War codebreaker for the US National Security Agency in the mid-1960s before chairing the mathematics department at Stony Brook University. His academic work with a colleague in the 1970s contributed to research in string theory, quantum field theory and condensed matter physics, according to his foundation.
Simons left academia and founded a hedge fund in 1978 that drew on his mathematical expertise. Renamed Renaissance Technologies in 1982, the firm pioneered quantitative trading strategies, which paid off notably for its Medallion Fund. The firm hired trained mathematicians and, according to its website, has about 300 employees, including 90 PhDs. The Medallion Fund stopped accepting external investors in 2005, and the firm grew its assets by tens of billions of dollars over the years, managing $60bn in 2021.
Simons relinquished day-to-day management of Renaissance in 2010 and stepped back from his co-chair role and the Simons Foundation in early 2021. The foundation, which he co-founded with his wife Marilyn in 1994, funds research in mathematics, basic sciences, life and physical sciences and autism, with several grant recipients later winning Nobel Prizes. Its 2022 annual report put assets at almost $5bn.
The firm's history also included turbulence. In 2021, Simons and other Renaissance executives agreed to pay about $7bn in back taxes and penalties to US federal authorities to settle a dispute over trades made by the Medallion Fund. Quantitative investing has since become a major part of the hedge fund industry, with firms such as DE Shaw, AQR and Two Sigma following Renaissance's approach.
Simons is survived by his wife, three children, five grandchildren and a great-grandchild. At a 2022 Abel Prize event, he summed up his career: "I did a lot of math, I made a lot of money, and I gave almost all of it away."
