Understanding AH Premium in China Stock Market

演讲内容简介:

There are a number of companies (AH-share) dual-listed in both China mainland stock market (A-share) and Hong Kong stock market (H-share) accounted for 20% of total A-share. The 'Shanghai-Hong Kong Stock Connect' program starting at November, 2014 makes previously two segmented markets--Shanghai and Hong Kong stock markets--connected. The price difference of AH-share in Shanghai and Hong Kong stock markets, measured by Hang Seng China AH Premium Index, persistently divergences instead of converging. We have shown that present-value asset pricing models with heterogeneous agents,which can explain price difference in the segmented markets, cannot generate any price difference in the connected markets. Market differentials between Shanghai and Hong Kong markets also quantitatively fail to explain such high and volatile AH premium. We, hence, propose an `Internal Rationality' learning model, in which agents don't know the pricing function from fundamentals to the stock prices and have different subjective beliefs about tomorrow's capital gains between Shanghai and Hong Kong markets. Our learning model can successfully generate data-like weekly AH premium. We also show that convergence traders with strategy short in Shanghai and long in Hong Kong would lose money with a high probability.
