It has forcedmanagers and academics to pay more attention to the effect of exchange rate volatilityon firm value, particularly in developed countries. In the 1990s Asian financial crises,the stock return volatility of US multinational firms increases significantly with therapid expansion of Asian currency crises to world stock market. It led academics andinvestors to pay increasing attention to examine exchange rate exposure in Asia stockmarkets. Nowadays the value of U.S. dollar increased volatility against Asian countries’currency since U.S. financial crisis beginning in August 2007.

In order to ensure our research’svalidity and reliability, sample firms are randomly chosen by the method of stratifiedsampling. The second step in this study is to examine the impact of firm-specific factorson sensitivity to exchange rate movement for those firms with a significant exchangerate exposure. The five firm specific factors are firm size, leverage situation, hedgingactivities, foreign involvement level, and industry classification.

The ordinary leastsquares method in SPSS program was used to estimate the parameters for eachindependent variable. Using a sample of 182 listed firms in these five sample markets, except China,exchange rate exposure of firms in other four Asian markets increases significantly insome sub-period during three sub-periods.
