In Depth Analysis of the Dually Listed Companies in Hong Kong and China Stock Markets Prior and Posterior to the Global Financial Turmoil

摘要

Given the close economic and political activities in Hong Kong and China, we expect the share prices of the companies co-listed in the two financial markets to go in tandem. In this paper, we re-visit the study of co-integration of companies listed in Hong Kong (H-shares) and in the Shanghai Stock Exchanges (A-shares), employing the Vector Error Correction Models (VECM) and Johansen Trace Test prior and posterior to the global financial crisis. Our results showed consistent and significant co-integration among these A- and H- shares co-listed in these markets.
