The current study documents an interesting phenomenon that retail investors prefer to invest in stocks listed at the stock exchange that is geographically close to them in China. This pattern is robust when we control for the well-documented local bias within a country. Among companies with similar distances to both stock exchanges, investors still display a much stronger tendency to invest in locally-listed companies. Among stocks with similar distances to both stock exchanges, those listed in Shanghai (Shenzhen) co-move more in returns and volume, with the benchmark at the Shanghai (Shenzhen) stock exchange. Such a preference for local exchange seems not to be motivated by information advantage, because investors do not obtain abnormal returns from their trades on stocks listed nearby. Our findings provide additional evidence that non-information-based familiarity bias induces investment and that such investor biases and exchange-level sentiment influence asset price formation.

China launched her warrant market in August 2005 in the split share structure reform of listed companies. As up to now, equity trading on margin and short-sale of any form are still prohibited in China. This warrant market enables investors to trade on information that otherwise might be prohibitively expensive to trade on. The Chinese warrant market created top trading volume and turnover with only a handful of different warrants traded. This paper first studies the Chinese warrant market. Empirical evidence shows that the market prices of warrants are much higher systematically than the Black-Scholes prices with historical volatility. Moreover, the paper documents ample evidence that the one-dimensional diffusion model does not apply well in the Chinese warrant market. The prices of a warrant and its underlying asset do not support the monotonicity, perfect correlation and option redundancy properties. The paper also studies the cumulated gains of a delta-hedged warrant portfolio. In the Chinese warrant market, the cumulated delta-hedged gains for almost all expired warrants are negative. The negative gains are mainly driven by the volatility risk, and the trading values of the warrants for puts and the market risk for calls. The investors are trading some other risks in addition to the underlying risk.

Current integration and co-movement among international stock markets has been boosted by increased globalization of the world economy, and profit-chasing capital surfing across borders. With a reputation as the fastest growing economy in the world, China’s stock market has continued gaining momentum during recent years and incurred growing attention from academicians, as well as practitioners. Taking into account economic and geographical considerations, the US and Hong Kong are considerably the most comparable stock markets to China. As the usual vector error correction model (VECM) could overlook the long memory feature of cointegration residual series, which can in turn exert bias on the resulting inferences, we chose to employ a fractionally integrated VECM (FIVECM) in this paper to investigate the long-term cointegration relations binding China’s stock market to the aforementioned stock markets. In addition, by augmenting the FIVECM with multivariate GARCH model, the return transmission and volatility spillover between market return series were revealed simultaneously. Our empirical results show that China’s stock market is fractionally cointegrated with the two markets, and it appears that China’s stock market has stronger ties with its neighboring Hong Kong market than with the world superpower, the US market.

This study adopts the Markov-switching ARCH (hereafter SWARCH) model to examine the volatility nature and volatility linkages of four segmented Chinese stock indices (SHA, SZA, SHB, and SZB). Our empirical findings are consistent with the following notions. First, we find strong evidence of regime shift in the volatility of four segmented markets and SWARCH model appears to outperform standard GARCH family models. Second, although there are some common features of volatility switch in segmented markets, there exist a few difference: (i)compared with the A-share markets, B-share markets are more volatile and shift more frequently between high- and low-volatility states; (ii) B-share markets have longer stays at high volatility state than the A-share markets; (iii) the relative magnitude of the high volatility compared with that of the low volatility is much greater than the case in two A-share markets. Third, B-share markets are found to be more sensitive to international shocks, while the A-share markets seem immune to international spillovers of volatility. Finally, analyses of volatility spillover effect among the four stock markets indicate that the A-share markets play a dominant role in volatility in Chinese stock markets.

Two motivations of internal financing in business groups are studied using Chinese data: cross-financing to relieve severe financing constraints, and expropriation from minority shareholders in environments with weak corporate governance. We document the existence of both, and discuss their implications on both the efficiency and magnitude of intra-group financing. We find that, from the business group perspective, the internal capital market is most efficient when the groups are well governed and have a pressing need to mitigate external financing constraints.

This paper investigates the potential benefits of international diversification with short selling constraints from the perspective of Chinese investors. Based on a stream of time-rolling realized portfolios, we show that Chinese investors can gain substantially from international investments. In particular, the expected portfolio returns as well as the risk-adjusted returns can be greatly enhanced by diversifying over emerging markets, and the portfolio risk can be largely reduced by investing in developed markets in comparison with purely domestic investments. The results are robust when the out-of-sample tests are employed and when investors start with a more mean-variance efficient domestic portfolio. In addition, our analysis illustrates that optimal portfolio weights vary significantly over time due to fluctuations in the correlations among international markets, suggesting that international portfolios need to be rebalanced frequently in order to generate the greatest possible diversification benefits.

Based on detailed trade records of individual investors who participated in both China’s A- and B- share markets, we find investors are more likely to buy A (B) shares when the A-share premium is lower (higher), when they have already held the same firm’s A (B) shares and when they have previously traded the same firm’s A (B) shares. Given that the correlation between the same firm’s A and B shares is below 70% and that A shares are more expensive, it is sensible for investors to invest more into the B shares. Our evidence suggests that investors accept a less than optimal portfolio due to lack of investment experience.

This study examines the effects of different dimensions of financing constraints (financial market development, governance environments, ownership control and other firm-specific characteristics) on cross-border mergers and acquisitions (M&As) for all takeover bids announced in nine East Asian economies from 1998 to 2005. The results of logistic regressions verify that the extent of stock market and governance developments encourages cross-border M&As in this region. The results also indicate that firm-specific financing constraints, except the ownership control variables, reduce the occurrence of cross-border M&As related to domestic M&As. Although family- and state-controlled firms have better access to external financing, they are reluctant to risk diluting their management control and thus prefers less cross-border M&As to domestic M&As. This study enhances the empirical studies of the financing constraint-investment relation based on the market imperfection theory in corporate finance theories. Information asymmetry is the main reason causing the market imperfection and leading to financing constraints to corporate investments. This study, by examining the relation over nine East Asian firms, thus provides an understanding of how such a relation fits in the firms in countries where information asymmetry is high.

We examine the effects of government ownership on the change in valuation and the uses of proceeds of firms after they raise equity funds – the time when the agency problems of free cash flows are larger. We find that investors generally react more negatively to an equity offering decision by a company whose government ownership is higher. Firms generally increase cash dividend payments after offering equity, and firms with extremely high government ownership increase cash dividends more than other firms do. Further analysis shows that investors react more negatively to an offering decision if they expect the issuer to increase cash dividends post-offering. Our study suggests agency problems exist in equity offerings in China, and firms tunnel resources by offering shares to the public followed by an increase in cash dividends.

Using the data of privately-owned firms in China’s transition economy, we examine the effects of soft budget constraint on the expropriation of minority shareholders. We find that, compared to small firms, large firms have higher bank loans and are more likely to get government subsidies. However, large firms show higher divergence between cash flow and control rights, more fund occupation by controlling shareholders, and lower market valuation. Moreover these differences between large and small firms become particularly pronounced when the firms operate in the provinces with poorer fiscal conditions. These findings suggest that soft budget constraint can mitigate the expropriation costs of controlling shareholders, and subsequently deteriorates the expropriation of minority shareholders.
