dc.titleStock repurchase and performance in China A-share marketen_US
dcterms.abstractStock repurchases, or share buybacks, have gained global attention in corporate finance for their role in enhancing shareholders’ value, allocating resources, and signaling confidence in future prospects.en_US
dcterms.abstractThe China Securities Regulatory Commission (CSRC) has recently implemented policies to encourage public firms to engage in stock repurchases for capital market stabilization. This policy shift could potentially impact individual stock returns and the performance of the China A-share market index.en_US
dcterms.abstractThis study utilizes data from the A-share stock repurchase database on the Wind, covering the period from January 1, 2005, to April 30, 2025. A total of 12,725 completed repurchase cases were successfully identified as the subjects for empirical analysis. The findings of this research are as follows:en_US
dcterms.abstract1. Stock repurchases are positively correlated with both short-term and long-term abnormal returns in the China A-share market, particularly surrounding the authorization announcement. However, empirical analysis reveals no statistically significant correlation between the cumulative volume of subsequent stock repurchases and long-term abnormal returns in this market—a finding that contrasts with established evidence from other major markets (Bargeron et al., 2017).en_US
dcterms.abstract2. The effects of repurchases are more pronounced for growth stocks in the short term, whereas the effects are more significant for value stocks and small market cap in the long term.en_US
dcterms.abstract3. Repurchases during bear markets do not generally yield higher alpha. In the short term, stock repurchases of growth stocks are more effective in bear markets. In the long term, regardless of market conditions, repurchases of small-sized stocks demonstrate greater efficacy, while repurchases of middle-valued stocks consistently underperform high or low valued stock repurchases in bear markets.en_US
dcterms.abstract4. Regardless of the time frame, the effects of repurchases are less pronounced for cancellation stock repurchases compared to other types of repurchases.en_US
dcterms.abstractThis study aims to contribute to existing literature by examining the effects of stock repurchases in the China A-share market context, demystifying why some repurchases are more influential on stock performance, so as to provide practical implications to investors as well as policy makers.en_US
