Abstract

This paper analyses whether we can predict South African stock returns based on a measure of economic policy uncertainty (EPU) of South Africa and twenty other developed and emerging markets. While, linear Granger causality tests fail to find evidence of predictability, barring couple of cases, strong evidence of causality is detected from all the EPUs using a nonparametric causality-in-quantiles test. In addition, predictability is found to hold over the entire conditional distribution of stock returns, with the same being strongest around the median, i.e., when the stock market is in a normal mode. Given the existence of nonlinearity and regime changes in our data set, we consider the results from the nonparametric test as more robust relative to the standard causality test.
