Does Stock Price Synchronicity Represent Firm-Specific Information? The International Evidence

Abstract

Much of prior international accounting research implicitly assumes that stock prices capture similar amounts of firm-specific information across countries. Recent research asserts that stock price synchronicity, defined as the R2 from asset pricing regressions, is a useful measure of the amount of firm-specific information impounded in stock prices in international markets. However, the results of our empirical tests provide little support for using stock price synchronicity as a measure of firm-specific information internationally. We develop an alternative measure of firm-specific information impounded in stock price based on the percentage of zero-return days, i.e., the zero-return metric, and repeat the analyses. Overall, our results suggest that the zero-return metric is a better measure of firm-specific information impounded into share prices than the synchronicity measure internationally.
