Title The analysis of the influencing factors of the IPO underpricing in China’s growth enterprise market
Abstract
The phenomenon of IPO underpricing widely exists in the stock market all over the world. China is undergoing economic transition period right now, and the capital market is imperfect compared to the Western market. The IPO underpricing ratio keeps high. The growth enterprise market (GEM) of China officially launched in October, 2009, more or less than 2 years by now. As a fresh thing, the rate is especially high. The research of the IPO underpricing of China’s GEM has a strong theoretical and practical significance. It can improve and stabilize the GEM system, enhance the efficiency of small and middle enterprise financing and improve the operating environment of China’s capital market.
This paper focuses on the influencing factors of IPO underpricing in China’s GEM. First we reviewed the relevant theoretical results at home and abroad, based on which we conclude the five major influencing factors combined with the background and market characteristics of China’s GEM. The five major factors are asymmetric information, investor sentiment, company growth, market index and the ownership concentration. Then ,in the empirical analysis sector, we choose 12 explanatory variables on behalf of the five factors to do the multiple regression analysis of GEM IPO underpricing rate and we got the conclusion that: the issue size, the time interval between the issue date and the listing date, the turnover rate on the first listing day and the issuing success rate have significant effects on China’s GEM. At last we give some suggestions. We believe that improving the information disclosure system and the market transparency, strengthening investor education and quickening the initial public offering of the eligible companies are good for the development of China’s GEM.
