Investors' Fear and Herding Behavior: Evidence from the Taiwan Stock Market

摘要

This article analyzes the influence of investors' fear on their investment behavior in the Taiwan stock market. This study used the volatility index (VIX) as a barometer of investors' fear. Our results show that herding behavior increases with the VIX; that is, herding behavior is encouraged by an increase in investors' fear. Moreover, our results demonstrate that investors react more quickly to bad news than to good news when their fear increases, supporting the hypothesis of the presence of an asymmetric reaction to news. However, investors react more quickly to good news when their fear decreases, indicating an inverse asymmetric reaction. In addition, our empirical results reveal that herding behavior tends to exist on days with a large trading volume.
