Switches in price discovery: Are U.S. traders more qualified in making valuations?

Abstract: The literature on the price discovery of dually listed stocks postulates that domestic markets generally dominate in driving changes in prices and make a strong contribution to price discovery. In this study, we provide evidence challenging this view. We analyze a case of two dually listed mobile communication firms that experienced a more than 80% loss in their value in response to a regulatory decision to allow other new operators to enter the communication market in the domestic market. We find that during the negative momentum period, price discovery switched from the domestic to the foreign market, making the NYSE more important in terms of price discovery. Our findings suggest that, regardless of the origin of the news, such dramatic shocks that carry long-term implications are processed differently, with U.S. traders, rather than the domestic ones, being the main information processors.
