Method and apparatus for an integrative model of multiple asset classes
First Claim
Patent Images
1. A computer implemented aggregate risk model for a plurality of asset classes, where construction of the aggregate risk model comprises the steps of:
- integrating a plurality of factor models corresponding to the plurality of asset classes, where integration of the plurality of factor models is based at least in part on;
one or more global factors (g) that capture covariance among factors (f) associated with the plurality of factor models; and
exposures (Y) of the factors (f) associated with the plurality of factor models to the one or more global factors (g).

Abstract
The invention provides a method and apparatus for combining two or more risk models to create a risk model with wider scope than its constituent parts. The method insures that the newly formed risk model is consistent with the component models from which it is formed.

31. A computer implemented method for combining two or more risk models to provide an aggregate risk model for a plurality of asset classes, for risk analysis, comprising the steps of:
-
determining a factor risk model, having one or more factors, for each of the asset classes;
