This article analyzes multifactor models in the presence of a large number of potential observable risk factors and unobservable common and group-specific factors. We show how relevant observable factors can be found from a large given set and how to determine the number of common and group-specific unobservable factors. The method allows consistent estimation of the beta coefficients in the presence of correlations between the observable and unobservable factors. The theory and method are applied to the study of asset returns for A-shares and B-shares traded on the Shanghai and Shenzhen stock exchanges, and to the study of risk prices in the cross section of returns.
