About Jim Simons

  • The Medallion fund earned extraordinary returns before fees for decades, unheard of in the industry.
  • Simons was an esteemed mathematician and took part in the Chern–Simons theory.
  • Renaissance mainly employs scientists, mathematicians and programmers rather than classic investment analysts.
  • The Medallion fund has long been closed to outside investors; the 13F filing concerns the firm's other funds.

How to use this page

A 13F filing shows what a manager held on the last day of a quarter, published up to 45 days later. It is a snapshot, not a trading signal: the manager may already have bought or sold since. Learn more in How to read 13F filings.

For information only, not investment advice. 13F filings are delayed by up to 45 days and do not show cash, bonds, short positions or non-US stocks.
