Abstract
We document that corporate investment contributes to stock liquidity. This study demonstrates a positive relationship between abnormal corporate investment and stock liquidity in the cross-section. Moreover, stock liquidity improves more apparently for firms with financial constraints. Our robustness check confirms that the existing regularities cannot explain the current finding. This analysis suggests that corporate investment decreases the risk of a firm and that a change in the risk affects the behavior of a market maker, leading to an increase in stock liquidity
