Overreaction in the Hong Kong stock market

Overreaction reported in the equity markets of the United States, Spain, and Brazil is also observed in the Hong Kong stock market. The “loser” portfolios of the 33 stocks in the Hang Seng Index (HSI), on average, outperform the “winner” portfolios by 9.9% 1 year after the formation periods. Besides its emphasis on the importance of the Hong Kong market in international investment, this paper is unique in some special features related to the overreaction study. Hong Kong has markets for index futures and stock futures. Only three stocks are used in the portfolios. All the stocks in the HSI have large market capitalization and liquidity and can be shorted with no up-tick rule. Unlike other studies in international stock markets, the “arbitrage” portfolio of buying the loser portfolio and shorting the winner portfolio can actually be formed with minimum cost and easy execution, which makes the overreaction phenomena in this study very powerful.

The underperformance of the growth enterprise market in Hong Kong

This paper examines the stock return performance of the IPO stocks which are listed on the Growth Enterprise Market (GEM) in Hong Kong. By using several benchmarks, over 3 years, this paper finds that the results produced are sensitive to the benchmark employed. The two factors causing the underperformance of GEM stocks are the ‘technology boom’ and ‘IPO effects’. This suggests that appropriate benchmarks are very important for assessing the performance of newly issued stocks. The results of the cross-sectional analyses suggest that the Hong Kong GEM is a unique market. Since at least 70 percent of the IPO stocks listed on the GEM are technology stocks, the ‘technology’ factor outweighs the various hypotheses advocated by previous researchers to explain the poor performance of newly listed stocks.     

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.

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.

The impact of the Japanese market on the intraday Hong Kong stock returns

This paper examines the impact of the price movement of the Japanese market on the Hong Kong market. We find that the Hong Kong stock prices react rapidly to the return information of the Japanese market. The evidence also indicates that the large price movement of the Japanese market can be used as an indicator for the Hong Kong market. The price reaction of the Hong Kong market is instantaneous and takes place in the opening minutes of the afternoon session. However, there is no excess profits when the transactions costs are included. Finally, the Hong Kong market has a significantly higher turnover when the Japanese market is open.     

On investment banker monitoring in the new issues market

This article primarily addresses two largely unanswered questions in the financial economics literature: (i) is there a demand for lead bank monitoring in the initial public offering (IPO) market?, and (ii) does monitoring by the lead investment banker lead to better post-issue performance? We find evidence consistent with the demand for underwriter monitoring in the IPO market. We examine variables which proxy for the incentives of lead underwriters to supply monitoring post-issue. These variables include lead investment bank reputation and whether warrants are issued to the underwriter by the issuing firm. We find that lead bank reputation is positively associated with the post-issue performance of IPO firms. We also examine whether additional value added monitoring is provided by unaffiliated analysts. The number of unaffiliated analysts following is positively correlated with post-issue performance. Our results are consistent with third party monitoring in the new issues market.     

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.     

The determinants of short selling: evidence from the Hong Kong equity market

While most financial regulators agree that short sellers have an important role to play in ensuring an efficiently functioning market, it is interesting to note that many did not hesitate to ban short selling during the recent financial crisis. This apparent contradiction most likely stems from a lack of understanding about what motivates short trading. In this paper, we focus on the determinants of short selling during ‘normal’ trading in the Hong Kong stock market. We find that dividend payments, company fundamentals, risk, option trading, the interest rate spread and past returns and short selling are all significant determinants of short selling.

Product market advertising and new equity issues

We analyze the interaction between a firm's product market advertising and its corporate financing decisions. We consider a firm that faces asymmetric information in both the product and financial markets and that needs to raise external financing to fund its growth opportunity (new project). Any product market advertising undertaken by the firm is visible to the financial market as well. In equilibrium, the firm uses a combination of product market advertising, equity underpricing, and underfinancing (raising a smaller amount of external capital than the full information optimum) to convey its true product quality and the intrinsic value of its projects to consumers and investors. The following two predictions arise from our theoretical analysis for the relation between product market advertising and equity underpricing around new equity issues. First, firms choose a higher level of product market advertising when they are planning to issue new equity, compared with situations in which they have no immediate plans to do so. Second, product market advertising and equity underpricing are substitutes for a firm issuing new equity. We empirically test the above two predictions and find supporting evidence in the context of firms making initial public offerings and seasoned equity offerings.     

Underwriters' allocation with and without discretionary power: Evidence from the Hong Kong IPO market

This study uses a unique and extensive data set from the Hong Kong IPO market to examine the theory of adverse selection under two distinct regulatory regimes in relation to underwriters' discretionary power in IPO share allocation. Consistent with Rock's (1986) theory of adverse selection in the IPO market, we show that, prior to the introduction of the clawback provision; retail (uninformed) investors were allocated more of the overpriced offerings and less of the underpriced issues. However, after the provision is implemented, retail investors have been allocated significantly more of the underpriced offerings and less of the overpriced ones. Overall, we find that allocation-adjusted initial returns for the retail investors are lower (higher) than the risk-free rate pre- (post-) clawback provision. These findings imply that the mandatory clawback provision has enhanced the fairness in IPO share allocations among different investor groups and has reduced the winner's curse in the IPO market.     

Short sales and speed of price adjustment: Evidence from the Hong Kong stock market

We present empirical evidence that short sales contribute to market efficiency by increasing the speed of price adjustment to not only private/public firm-specific information but also market-wide information. Shortable stocks are characterized by weaker trade continuity and stronger quote reversals. They adjust faster to new information than non-shortable counterparts. These findings remain robust even in an “up” market condition in which short sales are not binding. The amount of information incorporated in each trade is also significantly higher for shortable than non-shortable stocks in both “up” and “down” market conditions. After controlling for firm size, trading volume, liquidity, price and option trading, short sales stand out as one of the significant factors that speed up the price adjustment.     

On the conditional pricing effects of beta,size, and book-to-market equity in the Hong Kong market

Using Hong Kong equity stock data, this study examines empirically the pricing effects of beta, firm size, and book-to-market equity, but conditional on market situations, i.e. whether the market is up or down. Evidence supports the hypothesis that, if the risk variable is priced by the market, then there exists a systematic but conditional relation between the risk variable and average return, and this relation takes on opposite directions during up and down markets. However, the significance of the relations is often affected by the changing values of the risk variables as a result of changes in market conditions. Specifically, it is found that all three risk variables, namely beta, size, and book-to-market equity, exhibit conditional pricing effects. This is the first comprehensive study of its kind on Hong Kong market, which provides out-of-sample evidence relative to earlier tests on US data. The findings give important insights into capital market behaviour, which should prove useful in investment management and corporate financial decisions.
