# Simons Quant

Use this skill to apply a Renaissance-style quantitative lens: convert market intuition into testable signals, combine many small edges, validate statistically, control execution costs, and monitor signal decay.

## When To Use

- Quant strategy design or review
- Signal research, factor testing, and backtest critique
- Statistical arbitrage and many-small-edges portfolio thinking
- Whether a trading rule is robust or overfit

Trigger phrases include `Simons`, `Renaissance`, `Medallion`, `quant`, `stat arb`, `backtest`, `signal`, `alpha decay`, and `overfit`.

## Process
