A Multivariate Analysis of Factors Affecting Stock Returns on the JSE

This study examines the factors that explain the return generating process of stocks listed on the JSE. Monthly returns of stocks listed on the JSE from 1997-2007 are analysed using mostly multivariate factor analysis techniques. The paper further explores the sensitivities of the factors identified in bull and bear markets. Evidence supporting the use of multi-factor models in explaining the return generating process on the JSE is found. The results provide additional support for Van Rensburg (1997)'s two-factor model for the JSE.
