Investor attention and currency performance: international evidence

This article investigates the relationship between investor attention measured by Google search volume index and the performance of several currencies. We find that currency performance is remarkably responsive to changes in investor attention. These impacts, generated rapidly, are present over the relatively long term, especially for emerging currencies, and are intensified during periods of high uncertainty. We also demonstrate that there is a prominent asymmetric effect for the impact of attention, as past currency performance also influences attention. Typically, past currency performance can determine the magnitude of the impact on current currency performance. Moreover, we confirm that investor attention has a predictive power for forecasting emerging currency performance in the out-of-sample analysis. Further, these forecasts generate substantial economic value in the framework of asset allocation. By contrast, statistical predictability and economic value do not exist in the currencies from developed markets. These results indicate that investor attention can alter currency performance and its predictability. More broadly, our study emphasizes the potential of employing investor attention for emerging currency performance forecasting applications.
