Testing for Predictability in Conditionally Heteroskedastic Stock Returns

Westerlund, Joakim LU and Narayan, Paresh (2014) In Journal of Financial Econometrics
Abstract
The difficulty of predicting stock returns has recently motivated researchers to start

looking for more powerful tests, and the current paper takes a step in this direction.

Unlike existing tests, the test proposed here exploits the information contained in the

heteroskedasticity of findings, which is expected to lead to higher power, a result that is

confirmed by our results. In order to also maintain good size accuracy, subsample critical

values are used.
