A Study on AH Dual Listed Companies' IPO Underprice and Long-term Performance

摘要

In this paper, we use comparing research and regression analysis methods to study on the questions about AH dual listed companies' underprice phenomenon when they IPO in the A-share, and on their long-term performance. The empirical study results tell us that compared with the pure A-share listed companies, the AH dual listed companies have low first day return ratio, which means that the underprice degree of AH dual listed companies is lower. And we find that the long-term performance fluctuation of AH dual listed companies is smaller than the other part, so they can be treated as long-term investment objects.
