A large proportion of Chinese twin stocks is traded in both the Shanghai (A-share) and Hong Kong (H-share) markets. A-shares have sold at a premium, known as the AH premium; this premium is large (20--50%) and volatile. AH premium provides a natural experiment by which to test asset pricing models. We show that while various standard rational expectations (RE) and Bayesian RE asset-pricing models cannot explain the AH premium, a model of internally rational learning where agents learn about stock prices can provide a natural explanation. This finding emphasizes the importance of modeling investors who learn about equity prices.
