This paper investigates the pricing information transmission between the local Asian market and the US market by using daytime and overnight returns on forty-four Asian underlyingstocks and their ADRs. We have found that the return and volatility spillover from the underlying stock in the daytime Asian markets to its ADR in the overnightU.S. market is much stronger than the return and volatility spillover effect in the reverse direction from the U.S. market to the local Asian markets. We have also found that, in Korea and Japan, the Asian financial crisis has further intensified the information transmission in both direction from the local market to the US market and from the US market to the local market. That is, the extent of the return and volatility spillover effect between the Korea/Japan markets and the US market becomes stronger after the Asian financial crisis than before. On the other hand, most of the companies in New Zealand, China, Taiwan, and Hong Kong and many companies in Australia show insignificant change in the extent of the information transmission in either direction after the Asian financial crisis. We also looked into the information transmission between ADRs and underlying stocks issued by European firms, and found the similar results to those of Asian firms in that the transmission effect from underlying stocks to ADRs is stronger than the reverse effect.
