内容摘要：The lack of robustness in forecasting exchange rates has been explained in the literature as reflecting the potential instability of model performance. In this paper, we address model uncertainty by optimally combining the forecasts of several fundamental models according to the Mallows model averaging method proposed in Hansen (2007) and Liu (2015). Empirically, we apply this method to major exchange rates and find that our approach outperforms the random walk model with or without drift at a monthly frequency. Moreover, we reveal the underlying reason for why fundamental models cannot outperform random walk models in exchange rate prediction. Furthermore, the currency forecasts generate meaningful investment profits based on our approach.
