Disruption and stock markets: Evidence from Hong Kong

We examine the impact of disruption on stock markets using the 2019 Hong Kong protests for identification. We find that greater protest intensity corresponds to higher bid–ask spreads, lower trading volume, and greater return volatility for dual-listed Chinese firms’ Hong Kong (H) shares but not their home (A) shares. We also document negative abnormal returns only for these firms’ H-shares around major protest events, which shortly after exhibit reversal. Next, we validate our main findings by documenting similar results using Hong Kong-listed firms only. Overall, we provide new evidence highlighting the impact of protest-induced disruption on financial markets.     

Return spread and liquidity: Evidence from Hong Kong ADRs

Fifteen Chinese H-shares listed on the Stock Exchange of Hong Kong are cross listed as ADRs on the NYSE. We empirically determine the role of security specific liquidity associated with those ADRs and their underlying H-shares on return spreads, differences between the returns on ADRs and their corresponding H-shares after controlling for ADRs and H-shares excess market returns and their respective price inverses denoting conditional betas. We use three proxies for liquidity, trading volume, turnover, and illiquidity (Amihud, 2002) and find that only trading volume and turnover are consistent determinants of return spread for the majority of Chinese ADRs with primary listing in Hong Kong Stock Exchange (SEHK). We use a switching regression model and find that the model parameter estimates are not stationary and change, often drastically between pre and post 2000 and 2003. Further tests using Bai Perron indicate return spreads data as non-stationary with multiple regime changes during the sample period. Further the causes of non-stationarity seem to be largely security specific and not driven by broad market swings in either market.     

Issuer-oriented underpricing costs in initial public offers: Evidence from Hong Kong

This paper estimates the underpricing cost associated with new shares issued and sold when firms go public in a traditional British-style IPO market in contrast to prior work which focussed on the underpricing cost to pre-IPO investors. Secondly, the estimates account for interest income on application funds received by issuing firms. Using data from the Hong Kong IPO market, the results show that the issuer underpricing cost of new share issues is on average only 14% of headline underpricing. When interest on application funds is taken into account, net issuer underpricing cost reduces to just around 7% of headline underpricing. This finding provides a compelling explanation of why issuing companies may not be concerned about underpricing in traditional British-style IPO markets. Thirdly, we also find that pre-IPO investors take steps to minimise wealth transfer to new investors either by selling a very small proportion or none of their pre-IPO shares. These findings suggest that explanations of IPO underpricing to the various parties involved in the process should, in part, be sought in the institutional structures and investment banking practices of the relevant primary capital market.     

IPO price performance and block-trading activities: Evidence from Hong Kong

This research studies whether the trading behavior of IPO block holders is informative to small investors. The results show that IPOs have more block trades initiated by sellers on the first trading day than seasoned stocks do, and the level of block-trading activities is negatively associated with IPOs' long-term performance. This research also examines the impacts of the change in rules for IPO share allocations – which aimed at realizing a more even allocation between large and small investors – on IPO block-trading activities. The findings support the hypothesis that IPO block holders may have superior information on newly-listed companies.     

Information effects of dividends: Evidence from the Hong Kong market

The literature has suggested that earnings and earnings forecasts provide stronger signals than dividends about future performance of a firm. We test the information effects of simultaneous announcement of earnings and dividends in the Hong Kong market, distinguished by three interesting features (concentrated family-shareholdings, low corporate transparency, and no tax on dividends). Our results show significant share price reactions to unexpected earnings and dividend changes, but dividends appear to play a dominant role over earnings in pricing, a result contrary to findings in the literature. The signaling hypothesis works primarily for firms with earning increases, while the maturity hypothesis works mainly for firms with earnings declines.

The Determination of Rent in Shopping Centers: Some Evidence from Hong Kong

The purpose of this article is to assess the generality of previous empirical findings on the determinants of retail rent in shopping centers and validate their substantive robustness using data from Hong Kong. Consistent with previous findings, the rental rate of a retail unit is positively related to its customer-generating power and the size of the shopping center but negatively related to its own size. In contrast to previous findings, it is positively associated with chain stores and the age of the shopping center but not significantly related to several provisions in the lease.     

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.     

Short-Sales Constraints and Price Discovery: Evidence from the Hong Kong Market

Short‐sales practices in the Hong Kong stock market are unique in that only stocks on a list of designated securities can be sold short. By analyzing the price effects following the addition of individual stocks to the list, we find that short‐sales constraints tend to cause stock overvaluation and that the overvaluation effect is more dramatic for individual stocks for which wider dispersion of investor opinions exists. These findings are consistent with Miller's (1977) intuition and other optimism models. We also document higher volatility and less positive skewness of individual stock returns when short sales are allowed.     

Liquidity and asset pricing: Evidence from the Hong Kong stock market

This study investigates the role of liquidity in pricing stock returns in the Hong Kong stock market. Our results show that liquidity is an important factor for pricing returns in Hong Kong after taking well-documented asset pricing factors into consideration. The results are robust to adding portfolio residuals and higher moment factor in the factor models. The results are also robust to seasonality, and conditional-market tests. We also compare alternative factor models and find that the liquidity four-factor model (market excess return, size, book-to-market ratio, and liquidity) is the best model to explain stock returns in the Hong Kong stock market, while the momentum factor is not found to be priced.     

Board Structure and Intragroup Propping: Evidence from Family Business Groups in Hong Kong

Using earnings announcement events made by group member firms in Hong Kong, this study examines the governance role of boards of directors in curbing propping activities within family business groups. We find that earnings released by group member firms affect the stock prices of their nonannouncing group peers in a manner consistent with intragroup propping. More importantly, this effect is less pronounced when the announcing firms have a larger board or a board with a higher proportion of independent directors, but more pronounced when they have an executive director from their controlling families acting as board chairperson. Furthermore, the monitoring effect of boards of directors is strengthened for firms subject to new regulations increasing board power. Our results suggest that board oversight can mitigate propping activities.     

Ownership concentration and executive compensation in closely held firms: Evidence from Hong Kong

Controlling shareholders, who often manage the firms they control, can expropriate minority shareholders in many ways, which are usually referred to as “tunneling”. One of these ways is for owners–managers to set the level of their own compensation. We test the relationship between ownership concentration and executive compensation, using panel data for a sample of 412 Hong Kong firms during 1995–1998. We find a positive relationship between managerial ownership and cash emoluments for levels of ownership of up to 35% in small and in family controlled firms, and for up to 10% in large firms. Our tests show that the observed relationships do not result from compensation serving as a proxy for managerial effort. We interpret these findings as suggesting that in the presence of information asymmetry between entrenched managers and outside investors the former may use their ownership rights to extract higher salaries for themselves. There is also weaker evidence that top executives with larger shareholdings may be using dividends as a way of supplementing their cash salaries.     

Shortability and asset pricing model: Evidence from the Hong Kong stock market

This study explores how the violation of free short selling assumption affects the performance of CAPM and the Fama-French three-factor model, as existing studies show that short-sales constraints affect asset pricing of the stocks. Using data from the Hong Kong Stock Market which has unique regulations on short selling, we conduct both time-series and cross-sectional regression analyses to evaluate the performance of the two models under the short-sales-constraints and the no-constraints market environment. The two models perform much worse in the former environment than in the latter, indicating a significant impact of the short sales constraints on the explanatory power of the models. We then augment the two models with a shortability-mimicking factor. Our results show that the factor has a significant power in explaining both time-series and cross-sectional variation in the size-B/M portfolio returns. The addition of the factor to the two models considerably increases their overall performance.     

Contrarian investment strategies work better for dually-traded stocks: Evidence from Hong Kong

We investigate the profitability of contrarian investment strategies for equities listed on the Hong Kong Stock Exchange (HKEX), which are separated into cross-listed firms and firms listed only in Hong Kong. We also investigate the relationship between stock returns and past trading volume for these equities. We report significantly higher contrarian profits for the period investigated and find that this is a persistent feature of stock returns for cross-listed companies. We also document that contrarian portfolios earn returns as high as 8.01% per month for the dually-traded companies and just 1.83% for only HKEX-listed firms. We find that volume has only a limited ability to explain contrarian profits. All extreme profits disappeared after adjusting for the Fama and French three-factor model.     

Market Structure and Return Volatility: Evidence from the Hong Kong Stock Market

There is no consensus about the cause for higher volatility at the market open than at the market close in the U.S. market. As an order–driven, nonspecialist market, the Hong Kong stock market provides a useful setting for an examination. If halt of trade were the major cause of higher open–to–open volatility, the open–to–open volatility in the Hong Kong market would be higher. However, this is not observed. The autocorrelation of the open–to–open return series also indicates that the temporary price deviation at the market opening is not significant. We view these findings as consistent with the specialist argument.     

Noise from online discussion forums: Evidence from IPOs in China

In this study, we use initial public offerings (IPOs) in China to investigate how online stock forums influence information asymmetry and IPO valuation. The empirical analysis isolates the underpricing and overvaluation components of initial returns. The number of forum comments, postings, and readings are positively associated with initial returns and the degree of underpricing, implying that forums create noise that exacerbates information asymmetry during IPOs. This effect is amplified by the quiet period regulation, which drives investors to rely on online discussion forums to obtain information. Through sentiment analyses of forum posts and media coverage, we find that the negative effect of online forums is more prominent when bad news prevails. We clarify the role of online stock forums in IPO pricing and information asymmetry by separating underpricing from overvaluation in initial returns.     

Unintended regulatory consequences: Evidence from the Korean IPOs

We examine IPOs in Korea during the period August 2000–January 2002. We conclude that the high level of underpricing in Korean IPOs is the unintended consequence of regulations designed to promote fairness. Two aspects of the regulations distort the process — an “essential price” formula that severely understates the value of the firm; and, bid exclusion rules that give investors a strong incentive to cluster their bids so as to avoid being excluded from the offering. During our sample period the rules were changed somewhat. The result was a change to gaming behavior and somewhat less underpricing.     

Corporate Fraud and Business Conditions: Evidence from IPOs

We examine how a firm's incentive to commit fraud when going public varies with investor beliefs about industry business conditions. Fraud propensity increases with the level of investor beliefs about industry prospects but decreases when beliefs are extremely high. We find that two mechanisms are at work: monitoring by investors and short‐term executive compensation, both of which vary with investor beliefs about industry prospects. We also find that monitoring incentives of investors and underwriters differ. Our results are consistent with models of investor beliefs and corporate fraud, and suggest that regulators and auditors should be vigilant for fraud during booms.     

Value relevance of proportionate consolidation versus the equity method: Evidence from Hong Kong

Whether proportionate consolidation (PC) or the equity method (EM) provides more informative financial statements is a controversial issue. This study uses data from listed companies in Hong Kong to investigate the value relevance of the EM compared with PC during 2005–2008 when the local word-for-word equivalent HKAS 31 offered the same options. The results of this study provide evidence that PC does not offer higher value relevance than the EM. PC’s horizontal aggregation of a portion of the operations, assets and liabilities of the jointly controlled entities with those of the venturer is less informative to investors than the EM’s vertical aggregation.
