About Jim Simons & Renaissance Technologies

Renaissance Technologies is the quantitative firm founded by the late Jim Simons, a mathematician and former codebreaker. Its employee-only Medallion Fund is legendary for extraordinary long-run returns driven by statistical, model-based trading.

The 13F visible to the public reflects Renaissance's institutional funds (such as RIEF), showing an extremely broad, systematically diversified book of thousands of small positions rather than concentrated fundamental bets.
