Abstract:     
We examine the relation between stock volatility and asymmetric information empirically. We use two proxies of information asymmetry: institutional ownership and analyst coverage. We find that firms covered by more analysts are more likely to have less volatile returns. A significant and positive bilateral relationship between stock volatility and institutional block holdings is observed supporting possible herding behaviours of institutional investors.
