Modeling Non-normality Using Multivariate t : Implications for Asset Pricing

  title={Modeling Non-normality Using Multivariate t : Implications for Asset Pricing},
  author={Raymond Kan and Guofu Zhou},
In this paper, we propose to replace the widely used and firmly rejected multivariate normality assumption for the distribution of asset returns with a suitable multivariate t-distribution. Much of the asset pricing literature tries to explain expected returns on assets. In empirical studies, expected returns are often approximated by sample averages of realized returns. However, after replacing the normality assumption with a reasonable t-distribution, the most efficient estimator of expected… CONTINUE READING
