| Tiivistelmä: | Based on monthly returns of 95 German stocks during the period 1960 to 1994, a time series analysis of the CAPM is conducted. In a traditional Least Squares approach, CAPM residuals exhibit significant GARCH effects. A reanalysis of the data taking generalized ARCH effects into account leads to a higher precision in the estimated "Return-Betas", as measured by their estimated standard arrors. Furthermore, implications of GARCH modelling for a subsequent cross section analysis of the CAPM, as well as for tests of the efficient markets hypothesis are discussed. |
