Abstract

This paper explores different specifications of conditional return expectations. We compare the most common specification, linear least squares, with nonparametric techniques. Our results indicate that nonparametric regressions capture some nonlinearities in financial data. In-sample forecasts of international stock market returns are improved with nonparametric techniques. However, there is very little out-of-sample prediction power for both linear and nonparametric specifications of conditional expectations. If an asset manager relies on a simple instrumental variable regression framework to forecast stock returns, our results suggest that linear conditional return expectations are a reasonable approximation.
