Herding by foreign investors and emerging market equity returns: Evidence from Korea

摘要

This paper studies the effect of herding by foreign investors on stock returns in the Korean market. We conduct both pre and post-liberalization analyses and utilize a three-stage least squares analysis in order to control for the simultaneous relationship. We find evidence of a significant impact of foreign investor herding on stock returns in addition to intra-year positive feedback trading by foreign investors. However, changes in domestic institutional ownership do not have any significant effect on stock returns. In addition, foreign investors tend to buy/ sell shares that domestic institutions sell/buy in the herding year.
