A large literature has investigated predictability of the conditional mean of low frequency stock returns by macroeconomic and financial variables; however, little is known about predictability of the conditional distribution. We look at one-step-ahead out-of-sample predictability of the conditional distribution of monthly U.S. stock returns in relation to the macroeconomic and financial environment. Our methodological approach is innovative: we consider several specifications for the conditional density and combinations schemes. Our results are as follows: the entire density is predicted under combination schemes as applied to univariate GARCH models with Gaussian innovations; the Bayesian winner in relation to GARCH - skewed - t models is informative about the 5% VaR; the average realised utility of a mean-variance investor is maximised under the Bayesian winner as applied to GARCH models with symmetric student-t innovations. Our results have two implications: the best prediction model depends on the evaluation criterion; and combination schemes outperform individual models.
