About this website

This site is a primer on equity factor models, written for people who are quantitatively comfortable, or at least not scared by formulas. It goes from first principles to the details practitioners actually care about.

It’s written by Chris, who has spent two decades as a risk manager and quant developer at Deutsche Bank, BlueMountain Capital Management, and Citadel. He studied factor models under Gene Fama. He used factor models to explain the daily risk and performance of large portfolios. He wrote reporting frameworks that make it easier to use factor models. He orchestrated the overnight risk runs that analyzed the whole book before the open. He evaluated factors used in systematic trading strategies. He designed applications that hedge out unwanted factor exposures. He built the platform used for the research and production of some of the most cutting-edge, proprietary factor models.

In short: Chris likes factor models.

These days, he advises hedge funds and large family offices on using them well, and spends the rest of his time on projects outside finance. You shouldn’t dedicate your entire life to just factor models, after all.
