Abstract: By selecting 242 convertible bonds issued by 225 A-share listed companies from 2013 to 2022,this paper used the multiple linear regression method to empirically study the influencing factors of the stock price effect of their forced redemption announcements. The study found that:① the company's forced redemption announcement had a negative effect on the stock price;② the relative issuance scale and remaining scale of convertible bonds showed a significant negative correlation with the cumulative abnormal yield. The research conclusion verified the market effect of the forced redemption announcement of convertible bonds,and confirms the main influencing factors of the cumulative abnormal yield of convertible bonds,so it proposed the countermeasures and suggestions for convertible bond issuers,investors and market regulators.
