An empirical study of capital asset pricing model anomalies on the JSE.

Abstract

The introduction of the Capital Asset Pricing Model in 1964, and its subsequent study by hundreds of thousands if not millions of people at universities throughout the world, has had far reaching consequences in terms of the way portfolios were constructed for many insurance and pension funds. It has affected the investment philosophies of large numbers of investors as well as influenced the calculations of firms costs of capital. Countless investment proposals have been accepted or rejected based on what the Capital Asset Pricing model has calculated the minimum return demanded by shareholders to be. This dissertation looks at the empirical evidence supporting the debate about the usefulness of the Capital Asset Pricing model, as well as presenting evidence as to any possible anomalies to this model on the JSE.
