Foreign exchange trends are influenced not only by market supply and demand but also by government policies and macroeconomic changes in each country. In this study, DNN model uses various factors related to government policies as individual, and use US data as macroeconomic factors. Besides, this study also uses four strategies that has been discussed for long time, market portfolio, carry trade, momentum, and value. The individual factor will be multiplied and combined with macroeconomic factors and four strategy factor. Therefore, this study will use sixty (5+(7+4)*5) factors and separately input these factors into DNN and OLS models to predict the change of foreign exchange rate. Then, the predicted result will plus the interest rate differentials of each country, and get the predicted excess return. Next, use the predicted excess return to construct the High Minus Low portfolio. The performance of the HML portfolio will then be compared with the four trading strategies: market portfolio, carry trade, momentum, and value. Finally, the study will perform Permutation Importance to determine the most influential factor in the DNN model for this research.Empirical results reveal that the out-of-sample R^2 of the DNN model is higher than that of the OLS model. Furthermore, among the various strategies, the portfolio constructed by the DNN model exhibits the best performance. The factor importance analysis indicates that factors such as public debt, foreign exchange reserves, political stability, monetary base, CPI, gross purchases of domestic U.S security, gross purchases of foreign security from U.S, and value hold greater significance. These findings highlight the effectiveness of the DNN model in utilizing the information embedded in the factors within the current economic environment, a characteristic that traditional linear models lack.參考文獻 [1] Amat, C., Michalski, T., & Stoltz, G.
