Authors : Jieun Lee(BOK), KeeH.Chung(University at Buffalo, The State University of New York)
This study analyzes the effect of market volatility on stock returns using data from the Korean stock market from January 1, 2004 to December 31, 2014. We show that unexpected increases in market volatility accompany decreases in both stock returns and liquidity and the effect of volatility shock on stock returns is greater for stocks with more domestic or foreign institutional trading. Individual investors mitigate the negative effect of volatility shock on stock returns. The interaction effect of market volatility and liquidity on stock returns is stronger for stocks with more foreign institutional trading. We also document some evidence of asymmetric effects of market volatility on stock returns that are related to whether trades are buyer or seller-initiated.
