Hire no one from finance — the opposite of industry convention
RenTec's founding hiring rule: no economists, no finance professors, no MBAs. Only PhDs from mathematics, physics, signal processing, and linguistics. The reasoning is explicitly model-theoretic: people with finance training bring implicit priors about how markets work that contaminate the pattern-detection process. RenTec found edges that conventional finance had overlooked precisely because its employees couldn't see them through a finance lens.
- Ben:Simons said: we don't hire economists, we don't hire finance people, we don't hire MBAs. We hire people who are good at finding patterns in data.[Acquired Renaissance, ch. The hiring rule]
All positions systematic — no human discretion once the model fires
RenTec's trading is 100% systematic: when a model generates a signal, the position is taken without any trader override. This removes the principal-agent problem (a trader second-guessing a model because it contradicts their intuition) and means the firm's competitive edge is purely in the model-building and data infrastructure, not in individual trader skill.

Cap the Medallion Fund — refuse outside capital to protect the edge
Medallion is closed to outside investors and capped at ~$10B in AUM. Simons's reasoning: additional AUM would force trading at scale that moves markets, eroding the statistical edges the models exploit. RenTec deliberately left hundreds of billions of dollars of potential management fee income on the table to preserve a strategy that has produced the best investment record in history.
