Taking a Sophisticated Approach to Advanced Risk Modeling

We present a number of novel techniques introduced in the MAC3 GRM model with the aim of producing both accurate risk forecasts across multiple investment horizons, as well as for constructing reliable optimized portfolios. We argue that conventional risk models suffer from several specification errors, including: (a) spurious correlations between factor and specific return components, (b) systematic under forecasting the magnitude of factor correlations, and (c) improper decomposition between factor risk and specific risk. In this session, we describe the innovative solutions that Bloomberg has developed for solving these outstanding problems.
