The data of warrants underlying stocks was selected for the sample period from August,2005 to December,2009.These data the authors collected did not include the announcement date of reform of non-tradable underlying shares,and was available from Shanghai and Shenzhen stock exchanges.The event study method is employed to test the magnitude effect based on the Wild bootstrap,which is performed on the abnormal return,the cumulative abnormal return,and the standardized cumulative abnormal return.Empirical results show no evidence of magnitude effect but sign effect after warrants introduction.The authors argue that this phenomenon is caused by the migration of radical agents from stock market to warrant market.

The data the authors did not include the announcement date of reform of non-tradable underlying shares, and was available from Shanghai and Shenzhen stock exchanges The event study method is employed to test the magnitude effect based on the Wild bootstrap, which is performed on the abnormal return, the cumulative abnormal return, and the normalized cumulative abnormal return. Empirical results show no evidence of magnitude effect but sign effect after warrants introduction.The authors argue that this phenomenon is caused by the migration of radical agents from stock market to warrant market.
