Insider Trading in the Hong Kong Stock Market

Many previous studies on insider trading are based ondata in the U.S. capital market and conclude thatinsiders can earn abnormal profits. This paperexamines abnormal price performance associated withinsider trading in the Hong Kong stock market. We findthat abnormal profits associated with insider tradingare all concentrated on small firms. Trading volumedoes matter in determining the magnitude of thoseabnormal profits. Our results show that insiders ofmedium-sized and large firms do not earn abnormalprofits. Finally, it is found that outsiders who mimicthe information of insider trades associated withmedium-sized and large firms cannot earn abnormalprofits.     

Investor legal protection and earnings management: A study of Chinese H-shares and Hong Kong shares

Under the unique “one country, two systems” arrangement, the more stringent investor protection rules in Hong Kong are not enforceable in firms that are incorporated in China but listed on the Hong Kong stock exchange (H-shares). As such, H-shares and other local Hong Kong firms are subject to different investor protection regimes in the same stock market. We find that H-shares are associated with higher earnings management than local Hong Kong firms after controlling for disparity in economic development, types of controlling shareholders and other factors. More importantly, this relationship is weaker after China implemented the Securities Law in 1999. The results are robust after considering the dual-listing status of H-shares and board characteristics. These results provide direct evidence showing the effect of investor legal protection on financial reporting quality.     

Choice of foreign listing location: Experience of Chinese firms

At the end of October 2003, there were 237 Chinese firms' listings on various stock exchanges outside of Mainland China. Beyond geographical proximity and other obvious explanations of why Chinese firms prefer listing in Hong Kong more than in the United States, we identify two additional benefits of a Hong Kong listing. We find that Chinese firms listed in Hong Kong have a better information environment than those listed solely in the United States. We also find that the Hong Kong-listed firms are less financially constrained, which may be due to their ability to access the Hong Kong capital market for external financing. The results of our study show that different stock markets offer different benefits as a listing venue and the benefits of foreign listing may depend on the choice of listing location.     

Impact of family dominance on monitoring of earnings management by audit committees: Evidence from Hong Kong

This study examines whether the establishment of audit committees by Hong Kong firms would constrain earnings management, especially in firms with family-dominated corporate boards, a condition unique to Hong Kong. The study uses the methodology of three-stage (3SLS) regression analyses to control for endogeneity among earnings management, voluntarily established audit committee, and corporate board size. The results of regression analyses based on 523 observations for the period of 1999-2000 when the audit committees were first established by Hong Kong firms show that overall audit committees play a significant role in constraining earnings management even in the business environment of higher ownership concentration. The effectiveness of audit committees is, however, significantly reduced when family members are present on corporate boards, especially when family members dominate the corporate board.     

Ownership Structure, Corporate Governance, and Firm Value: Evidence from the East Asian Financial Crisis

We use a sample of 800 firms in eight East Asian countries to study the effect of ownership structure on value during the region's financial crisis. The crisis negatively impacted firms' investment opportunities, raising the incentives of controlling shareholders to expropriate minority investors. Crisis period stock returns of firms in which managers have high levels of control rights, but have separated their control and cash flow ownership, are 10–20 percentage points lower than those of other firms. The evidence is consistent with the view that ownership structure plays an important role in determining whether insiders expropriate minority shareholders.

Is dividend smoothing universal?: New insights from a comparative study of dividend policies in Hong Kong and the U.S.

In this paper, we develop new insights about the dynamics of corporate dividend policy by performing the natural experiment of comparing corporate dividend policies in Hong Kong and the U.S., two economies where the tax regime and equity ownership structure are significantly different. Our empirical results can be summarized as follows. First, a test of the Lintner model reveals that the extent of dividend smoothing by firms in Hong Kong is significantly less than those in the U.S. Second, the signaling effects of dividend changes on stock returns are stronger in the U.S. compared to those in Hong Kong. Third, our logit analysis of the determinants of dividend changes indicates that, while the lagged dividend yield significantly affects dividend changes in both countries in the same fashion, prior year stock returns have opposite effects on dividend changes in the two countries. Finally, the extent of dividend smoothing is not systematically related to blockholder equity ownership in either country. Overall, our results suggest that, compared to U.S. firms, Hong Kong firms pursue a more flexible dividend policy commensurate with earnings, and that the differences between the dividend policies of firms in the two countries are consistent with the signaling implications of the differences in the tax regime across the two countries.     

Corporate governance and firm performance

How is corporate governance measured? What is the relationship between corporate governance and performance? This paper sheds light on these questions while taking into account the endogeneity of the relationships among corporate governance, corporate performance, corporate capital structure, and corporate ownership structure. We make three additional contributions to the literature:First, we find that better governance as measured by the Gompers, Ishii, and Metrick [Gompers, P.A., Ishii, J.L., and Metrick, A., 2003, Corporate governance and equity prices, Quarterly Journal of Economics 118(1), 107–155.] and Bebchuk, Cohen and Ferrell [Bebchuk, L., Cohen, A., and Ferrell, A., 2004, What matters in corporate governance?, Working paper, Harvard Law School] indices, stock ownership of board members, and CEO-Chair separation is significantly positively correlated with better contemporaneous and subsequent operating performance.Second, contrary to claims in GIM and BCF, none of the governance measures are correlated with future stock market performance. In several instances inferences regarding the (stock market) performance and governance relationship do depend on whether or not one takes into account the endogenous nature of the relationship between governance and (stock market) performance.Third, given poor firm performance, the probability of disciplinary management turnover is positively correlated with stock ownership of board members, and board independence. However, better governed firms as measured by the GIM and BCF indices are less likely to experience disciplinary management turnover in spite of their poor performance.     

Legal Institutions,Ownership Concentration,and Stock Repurchases Around the World: Signal Mimicking?

One of the central puzzles of signaling theory is how to assess signal quality, in particular the potential for signal mimicking. Our study provides evidence of signal mimicking in the context of stock repurchases. Employing an ex-ante proxy for the likelihood of mimicking stock repurchases and data on open market stock repurchases from 30 countries, we find that long-term operating and market performance following stock repurchases improve less for suspected mimicking firms. This finding contradicts the conventional characterization that managers use stock repurchases to signal undervaluation and enhanced future performance. We find that mimicking firms have smaller capital investments, need greater external financing, buy back fewer shares, and issue more new shares (and/or resell more treasury shares) in the year of the repurchase. Our analysis further shows that mimicking is more likely in countries with weak investor protections and in firms with higher ownership concentration. Further, mimicking associated with concentrated ownership is mitigated in countries with stronger investor protections and by the adoption of International Financial Reporting Standards (IFRS). Altogether, our findings provide evidence of signal mimicking in stock repurchases in international data that is influenced by market, ownership, legal, and financial reporting characteristics of countries.     

Family control and idiosyncratic volatility: Evidence from listed firms in Hong Kong

Family control of listed firms in Hong Kong is substantively different and materially higher than in the US which could offer different insights into the effects of family ownership on corporate transparency. Using a sample of listed Hong Kong firms and idiosyncratic volatility as a proxy for firm-specific stock price informativeness, we find that family firms exhibit higher idiosyncratic volatility of stock prices than similar non-family firms. Further, the relation between family ownership and idiosyncratic volatility is weaker for firms with higher leverage but stronger in periods before equity issues. Additionally, we find that family firms disclose more information, particularly related to operations, than nonfamily firms in annual reports. These results are consistent with the argument that family firms disclose more information than their nonfamily peers to reassure skeptical outside investors that they are not expropriating their investment.     

The impact of board capital and board characteristics on firm performance

The purpose of this study is to investigate the effects of board capital on the relationship between CEO duality, board dependence, managerial share ownership and performance. We argue that board capital (the ability of board members to perform manager-monitoring activities and to provide advice and counsel to management) varies across board members. Highly qualified board members will be better at monitoring management and constitute a more valuable resource for firms. Based on a sample of U.S. companies listed in the Compustat S&P 500 and using both resource dependence and agency theories, we predict and find that CEO duality and board dependence negatively affect performance and that board capital mitigates the negative effects. We also predict and find that managerial share ownership positively affects performance and that board capital strengthens this positive relationship. The results are consistent with the view that firms benefit from board capital in terms of outside directors' ability to monitor managers and provide advice and counsel to managers.     

Time variation paths of international transmission of stock volatility — US vs. Hong Kong and South Korea

This study examines continuous time variation paths of sensitivities of the Hong Kong and South Korea stock markets to the US stock market and bond market (proxied by long-term interest rates) by using the Flexible Least Squares (FLS) estimation technique. The FLS findings suggest that changes in both the US stock market and US long-term interest rates may simultaneously have significant effects on the Hong Kong stock market in some time periods. In other periods, neither may have significant effects on the Hong Kong stock market. The results also indicate that the South Korea stock market is overall insensitive to changes in the US capital markets. However, it becomes more sensitive in the 1990s. Some macroeconomic variables may explain changes in the sensitivities of the Hong Kong and South Korea stock markets to changes in the US capital markets.     

Effect of ownership,governance, and transparency on liquidity – Chilean evidence

Companies with relatively thin trading, a high concentration of insider ownership, and a privatized pension system characterize Chile’s Santiago Stock Exchange. Within this setting, we study the relationship between ownership concentration, corporate governance, and stock market liquidity. Our results suggest that board independence, corporate disclosure and outside monitoring by institutions help moderate the effects that insiders have on trading costs and liquidity. We also find that market makers with inventory reduce the informational component of trading costs. Finally, the trades of insiders provide price guidance to market makers, while traders employ a follow-the-insider strategy when transparency is low.     

Competition For Board Seats Following Stock‐For‐Stock Mergers

We examine the board structure of firms following stock‐for‐stock mergers. We find that former target inside (outside) directors are more likely to join the combined firm board when target insiders (outsiders) have a relatively strong position on the pre‐merger target board. The relative size of the target firm, target firm profitability, and target blockholder ownership also influence whether target directors join the combined board. We conclude that competition for board seats on the combined board is won by target directors with greater bargaining positions.     

Do institutional investors reinforce or reduce agency problems? Earnings management and the post-IPO performance

This study investigates the dual roles of institutional investors in earnings management during initial public offerings (IPOs). Research suggests that institutional investors play a monitoring role in the corporate governance of firms by mitigating earnings management to reduce agency problems. However, institutional investors have incentives to opportunistically maximize their wealth by manipulating earnings when firms engage in IPOs. Results suggest that institutional investors facilitate accrual-based earnings management before IPOs but restrain earnings management after their issuance. We also find that firms with high institutional ownership experience superior post-IPO stock returns and operating performance, thereby suggesting that the capital market positively prices the monitoring function of institutional investors after IPOs, and the performance of these firms is improved. Our results are robust to controlling the endogeneity problem of institutional investors and further identifying active institutional investors.     

How cross-listings from an emerging economy affect the host market?

We study the impact of mainland Chinese listings in Hong Kong on the quality and development of the Hong Kong equity market. At the macro-level, we find that the increasing presence of mainland Chinese stocks in Hong Kong increases the size, trading volume, and its link with the China and world markets but reduces the overall volatility of the Hong Kong stock market. At the firm level, the increase affects the market quality, resulting in lower turnover rate, higher Amihud illiquidity ratio, and higher spread for non-mainland Chinese firms. Furthermore, such an increase in presence causes Hong Kong stocks to move in a more synchronized way and reduces these firms investment sensitivity to stock price movement, implying deterioration in the information environment. As a whole, the increasing presence of Chinese companies in Hong Kong brings benefits to the Hong Kong market, yet not without cost.     

Management succession and financial performance of family controlled firms

This paper examines the immediate and long-term impacts on financial performance of 124 management successions within Canadian family controlled firms. When family successors are appointed, stock prices decline by 3.20% during the 3-day (−1 to +1) event window, whereas there is no significant decrease when either non-family insiders or outsiders are appointed. However, a cross-sectional analysis indicates that the negative stock market reaction to family successors is related to their relatively young age which may reflect a lack of management experience rather than their family connection per se. Investors are uncertain about the “management quality” of family successors who have less established reputations than more seasoned non-family insiders and outsiders. Non-family member appointments tend to follow periods of poor operating performance implying that there might be more scope for improvement when a non-family successor is appointed. Unlike the US sample in McConaughy et al. [McConaughy, D.L., Walker, M.C., Henderson, G.V., Mishra, C.S., 1998. Founding family controlled firms: efficiency and value, Review of Financial Economics 7, 1–19.], which indicates that the median percentage of votes held by controlling families is less than 15%, the Canadian sample indicates a more concentrated ownership with the median percentage of family controlled votes exceeding 51%. Of the firms in our sample, 62% use dual class capitalization to maintain control within the family.     

Corporate Equity Ownership, Strategic Alliances, and Product Market Relationships

This paper examines long-term block ownership by corporations and performance changes in firms with corporate block owners. We also examine potential reasons for corporate ownership including benefits in product market relationships, alleviation of financing constraints, and board monitoring by corporate owners. We find the largest significant increases in targets' stock prices, investment, and operating profitability when ownership is combined with alliances, joint ventures, and other product market relationships between purchasing and target firms, especially in industries with high research and development. Our findings are consistent with the conclusion that block ownership by corporations has significant benefits in product market relationships.     

Stock market listing status and real earnings management

This study analyzes real earnings management among privately held versus publicly listed firms. Our first finding is that public firms engage in more earnings management through operating activities. When a clear incentive to manage earnings in a specific direction is present we continue to find that public firms manage their earnings more than private firms. We reason that capital market pressure and ownership characteristics drive our results. Additional analyses reveal that public firms employ more real earnings management as a proportion of the total earnings management strategy. Furthermore, we find that mitigating factors of real earnings management have stronger impact in public firms. This study contributes to literature on non-accrual earnings management and to the broader understanding about the private vis-à-vis public firm reporting and operating behavior. Finally, we contribute by identifying an important societal cost of stock market listing, which is the increase in potentially value-destroying real earnings management.
