The empirical results show that: 1.The abnormal return of the announcement of convertible bond by private placement is positive at the next day of event day. The abnormal return of the announcement of convertible bond by public offering is negative at the event day. 2.The cumulative abnormal returns between companies who issued convertibles by private placement and by public offering are not significantly different. 3.In terms of private placement of convertible bonds: Relative issue size, firm size and debt ratio are significantly positive related to the cumulative abnormal return. The proportion of insider ownership is significantly negative related to the cumulative abnormal return. Sales growth rate and P/B ratio are not significantly positive related to the cumulative abnormal return. In terms of public offering of convertible bonds: Sales growth rate and the proportion of insider ownership are significantly positive related to the cumulative abnormal return. P/B ratio and debt ratio are significantly negative related to the cumulative abnormal return. Relative issue size is not significantly negative related to the cumulative abnormal return. The relation between firm size and the cumulative abnormal return is not clear. 4.Those companies, which have larger relative issue size, higher sales growth rate, higher P/B ratio, larger firm size, would prefer issuing convertible bonds by public offering. Those companies, which have higher proportion of insider ownership, higher debt ratio, would prefer issuing convertible bonds by private placement.
