Market segmentation and dual-listed stock price premium - an empirical investigation of the Chinese stock market

Abstract

This thesis comprises, firstly, a careful and detailed description of the institutional workings of the Chinese stock market; secondly, a literature review of the Chinese segmented markets and dual-listed shares price premium; and thirdly, three evidence-based contributions designed to cast new light on the Chinese A-shares premium puzzle. Publicly-listed firms in China, under certain criteria, can issue two different types of shares, namely A-shares and B-shares, to local and foreign investors respectively. These shares carry the same rights and obligations, but are however priced differently due to market segmentation. After a review of the literature on determinants of the premium, the first contribution offers a complementary explanation. I propose that the premium reflects the difference in valuation preferences between the local and foreign investors, i.e., local investors pay more attention to stock liquidity, while foreign investors pay more attention to firm’s intrinsic value, and so firms having more favorable fundamentals tend to have lower premia. The second contribution involves the examination of a controversial question that which investor group is better informed about local assets, by testing the direction of information flows between the A- and B-shares markets. Both time series methods, and panel data techniques which are used for the first time in this context, are employed, in order to get a distinct and more insightful picture against the current literature. The third contribution compares and contrasts institutional settings of China, Singapore and Thailand which have similar market segmentation and dual-listing systems; examines whether or not the premia in the three countries are caused by same factors; and tries to answer why foreign investors in China pay less, rather than more, as commonly observed in other segmented markets, for identical assets. It provides the first cross-country comparison evidence after 1999 with updated data.
