Abstract
The Capital Asset Pricing Model (CAPM), jointly accredited to Markowitz (1952), Treynor (1961),
Sharpe (1964), Lintner (1965) and Mossin (1966), provides that, at equilibrium, the return on all
risky assets is attributable to their covariance with the market portfolio. This paper studies whether
the CAPM holds for the South African market (represented by the Johannesburg Stock Exchange),
by using the methodology developed by Fama and Macbeth (1973).
Furthermore, the paper expands on other factors that influence asset returns and interrogates
alternative asset pricing models.
The findings of the study on individual assets rejects CAPM in the context of South Africa. This is
consistent with other empirical studies. CAPM is also rejected for the Industrial Index as well as
the Top 40 index. What is interesting to note however, is that for the Resources index, CAPM is
validated.
