Study on IPO Underpricing and New Stocks Non-systemic Risk: A Test for the Hypothesis of Market Feedback

With the universal IPO underpricing in the world, and accompanying with the improved market maturity, the initial return tends to be reducing. This paper makes an empirical investigation on the tendency of IPO initial return movement in China and the effects of authorization system implementation. The indicational function of the initial return on the non-systemic risk is also analyzed in this paper. As the result shows that there is no distinct tendency in IPO initial return movement in China, the hypothesis of market feedback gets supported.
