Multifactor risk models and heterotic CAPM

Zura Kakushadze

Journal of Investment Strategies

Abstract: ABSTRACT We give a complete algorithm and source code for constructing general multifactor risk models (for equities) via any combination of style factors, principal components (betas) and/or industry factors. For short horizons, we employ the Russian-doll risk model construction to obtain a nonsingular factor covariance matrix. This generalizes the heterotic risk model construction to include arbitrary non-industry risk factors as well as industry risk factors with generic "weights". The aim of sharing our proprietary know-how with the investment community is to encourage organic risk model building. The paper is intended to be essentially self-contained and pedagogical.
