In this study, we investigate the impact of institutional trading on the market by examining the daily relation between aggregate flow into U.S. equity funds and market volatility. We differentiate the impact of fund inflow and outflow, respectively, on the market volatility. Our empirical results show that there exists an asymmetric concurrent relationship between fund flow and market volatility: fund inflow is negatively correlated with market volatility while fund outflow is positively correlated with market volatility. We also discuss the potential explanations for our results and suggest that our results are consistent with information content differences of funds' buys and sells.
