Exchange Rate Exposure: Do Asymmetries and Volatilities Matter? Evidence from the Taiwan Stock Market

R. F. Franck Varga


This study investigates foreign exchange exposure and the impacts of asymmetries and volatilities on the daily returns of Taiwanese non-financial firms from 1990 to 2010. 88.8% of our samples are negatively exposed, companies benefiting from an appreciation of the domestic currency. 14% of the firms have an asymmetrical profile. If this percentage is not negligible, Taiwanese firms exhibit mainly a symmetric exposure. Currency volatilities have a significant impact for only 7.5% of the firms, but for 37.38% of the sample, we observe the existence of an asymmetric volatility. Among them, 65% exhibit a negative sign meaning that good news have a greater impact on the volatility than bad news, which seems counter-intuitive. These results may be explained by a chasing good news behavior and the effects of a high level of information uncertainty.
