Abstract

We develop a Stochastic Dominance methodology to analyze if new assets expand theinvestment possibilities for rational nonsatiable and risk-averse investors. This methodologyavoids the simplifying assumptions underlying the traditional mean-variance approach tospanning. The methodology is applied to analyze the stock market behavior of small firms in themonth of January. Our findings suggest that the previously observed January effect isremarkably robust with respect to simplifying assumptions regarding the return distribution.
