This study examined whether capital flows have an effect on volatility of equity markets in Korea. The capital flows in transaction were classified by type of investors, type of security: domestic and foreign investors, equity securities and bonds. The empirical results of this study are as follows. Firstly, daily capital flows, used as a proxy for information arrival process, have insignificant explanatory power regarding the variance of daily returns, when contemporaneous and lagged capital flows are considered. Furthermore, GARCH effect persists in the financial market even after capital flows are included in the model. Secondly, when capital flow is decomposed into expected and unexpected components, volatility persistence in stock returns does not disappear. We found that both investors’ unexpected equity investment have a positive effect on volatility in stock returns market. Also, foreign’s unexpected activity in equity are much bigger than Korean’s unexpected activity in equity.
