我國A股送轉(zhuǎn)股公司的長期業(yè)績研究
[Abstract]:Aiming at the topic of "signal transfer effect of dividend", this paper, from the perspective of information connotation, makes an empirical study on whether the transfer behavior of listed companies includes the company's future performance information. The results show that the company's transfer behavior does not convey good information about the company's future performance. But this does not explain the widely observed phenomenon of "significantly positive excess returns on stock prices" before and after the event. Different from previous studies on short term excess return, this paper makes an empirical test on the long term excess return of the transferable company. The results show that the long term excess return is significantly negative. This, combined with the significantly positive cumulative excess returns observed by other scholars before and after the stock transfer incident, indicates that the share price of the company rose significantly in the short term during the transfer period, but declined slowly over a longer period of time. The event itself does not convey the company's future performance information. On the basis of industry distribution and profitability, a group of companies that are closest to the profitability of the company are selected as reference system and comparison benchmark. Specifically, when studying the operating performance of the transfer companies, the profit margin before interest and tax is taken as the research index to investigate the comparative situation of the profitability of the transfer companies and the control companies within four years after the implementation of the transfer. In the study of long-term market performance, based on the Fama-French three-factor model, the risk is controlled from the market angle, the scale angle and the value angle, and the long-term excess rate of return of the transferred company is investigated in combination with the zero portfolio.
