Actual Share Repurchases and Liquidity : Evidence from Thailand

This paper examines the impacts of actual share repurchases on stock liquidity of companies listed on the Stock Exchange of Thailand (SET) over 2001-2010. The results show that bid-ask spreads are narrower, price impact is lower, and turnover is higher on repurchase days compared to those on non-repurchase days. In addition, the number of actual shares repurchased is found to be negatively related to bid-ask spreads and price impact, and positively related to turnover. Overall, the findings clearly indicate that actual share repurchases have positive impacts on stock liquidity
