An alternative explanation for the relationship between stock prices and exchange rates is provided by the so-called traditional approach, like the model of Dornbusch and Fischer (1980).
In this view, exchange rates affect stock prices positively. A depreciation of the domestic currency increases international competitiveness and therefore improves the current account. Consequently, rising real output in turn positively influences the profitability and the value of firms, and therefore their stock prices. The response of stock prices to fluctuations in the exchange rate depends on their degree of exposure to exchange rate risks through channels like the degree of openness both in international trade and international capital mobility, the degree of foreign competition for firms with no international business activity and the degree of competition for factors of production (Dominguez and Tesar 2001).
