An Empirical Analysis of Stock Market Anomalies and Spillover Effects: Evidence from the Securities Exchange of Thailand

This study examines two interrelated but separate issues: cross-sectional predictability of equity returns in the Stock Exchange of Thailand (SET), and transmission of stock market movements. The first essay empirically investigates to what extent the evidence of three major documented stock market anomalies (earnings-price ratio, firm size, and book-to-market ratio) can be generalized across national stock markets. The second essay studies the price and volatility spillover effects from the New York Stock Exchange (NYSE) to the SET. The first essay, using the Fama-Macbeth procedure and the pooled time-series cross-sectional GLS regressions, finds a weak relation between the beta and average stock returns. The adjustment of estimated beta for the effect of thin trading does not change the implications of the results. Of the three anomalies investigated, the size effect has the most prominent and consistent role in explaining average returns. For the earnings-price ratio, the results indicate that the significance of the E/P ratio variable persists only if the nonfinancial firms are considered. In contrast to the previous empirical results for the U.S. and Japanese stock markets, the book-to-market ratio fails to explain the SET equity returns. The second essay employs a generalized autoregressive conditionally heteroskedastic (GARCH) model with conditional t-distributed errors to investigate the spillover effects. No evidence of price spillover effects is found for the full sample period. However, the spillover effects are significant during the period in which the Federal Reserve Board raised interest rates. Further examinations reveal that information inferred from price changes in the U.S. market influences only the opening price in the SET, not the open-to-close Thai stock market returns. This implies that price in the SET is informationally efficient with respect to the price determined in the U.S. stock market. The evidence is generally supportive of international financial integration and informational efficiency in the Thai stock market.
