Many Chinese firms have pursued overseas listings in Hong Kong or U.S. without being first listed in China’s domestic market, mainly due to the regulatory constraints imposed by the Chinese government. Some of them eventually returned to mainland China through an A-share offering to Chinese investors. This unique feature of cross-listed Chinese stocks offers an experiment field to test some of the conventional theories of IPO underpricing. Homebound IPOs are expected to be less underpriced than domestic only IPOs that are not cross-listed because being already listed in a developed market can mitigate the information asymmetry and issue uncertainty associated with their A-share IPOs. Nevertheless, we find that homecoming A-share IPOs are still substantially underpriced, with an average market adjusted first day return of 96.53%. Furthermore, their first-day returns are not significantly different from those of domestic only IPOs once firm- and offer characteristics are controlled. This is in sharp contrast to the lukewarm aftermarket performance experienced in their overseas debuts. Overall, our results suggest the importance of local market structures and norms as influential factors of IPO underpricing
