Empirical Analysis of Investors’ Herding Behaviours during the Market Structural Changes and Crisis Events: Evidence from Thailand

Abstract

ABSTRACT This study investigates herding behaviour of investors in Thailand under different market conditions, crisis periods, and major market structural changes. The results show that herding behaviour occurs during an extreme market movement of negative or positive returns, in the declining market environment, on days with high trading volume, and during economic downturn as measured by negative GDP output gap. The structural break point analysis and rolling regression technique further shows that herding behaviour gathered heavily around 1997 Asian crisis. The establishments of internet trading platform, bond electronic trading exchange, and future electronic exchanges in Thailand do not make investors herd.
