Abstract
In the information economy epoch, the network media, as an information intermediary plays a guiding role in the operation of the Chinese stock market, causing strong incitement to investors. This paper aims to explore the impact of online media attention on initial public offering (IPO) underpricing from the double perspective of investor sentiment and behavioral finance through empirical research. Particularly, we studied a representative stage of China's stock market, with 756 valid IPO samples. The empirical result indicates that the IPO underpricing degree of the Growth Enterprise Market (GEM) is significantly lower than that of the Mainboard and Small and Medium Enterprise Board (SME); Turnover rate (Tnov) and price-earnings ratio (Pe) on the first day of listing will deepen IPO underpricing, while return on equity ((ROE) ̅) and offering size (Size) will mitigate the problem of IPO underpricing.
