This study investigates the trading activity of Chinese stock index futures, recently introduced at the open and close of the underlying trading. We document the impact of the underlying spot on the futures market liquidity as well as volatility as discussed in earlier works on market closure theory. Our empirical results support previous literature on the impact of the underlying, particularly during the open session, as a contagion effect, which is clearly at play. We find significant U-shaped patterns in liquidity factors and intraday volatility during open and close trades in the morning.

This study investigates the impact of monetary policy on liquidity of Vietnam’s stock market from September 2007 to November 2014. Time series of liquidity are determined by monthly liquidity data for 643 enterprises in the surveyed period. Two variables of the monetary policy, including growth in money supply and interbank rate, are employed in VAR model along with four different measures of market liquidity. The results show that unexpected variance in the two monetary policy variables has no significant impact on the market liquidity, which, in turn, may be improved by the positive shocks of market returns, inflation, and growth in industrial production. Market variance does produce certain effects, but discrepancies occur in the signs of various liquidity measures.

The purpose of this chapter is to examine the drivers of secondary bond market and stock market liquidity for investment analysis after global financial crisis in Turkey. The literature in Turkey mainly focuses only on the volatility of return for driving liquidity in both bond and stock markets. However, it is argued that other types of volatilities including domestic and international volatilities have also a deteriorating impact on secondary market liquidity in Turkey. In this context, it is empirically tested whether the volatility and/or uncertainty that stem from the FED and ECB policies within the last 10 years had a negative impact on liquidity both in government bond and stock markets. Moreover, the impact of non-residents in bond and stock markets on secondary market liquidity is examined by including their holdings in stock and bond market.

Purpose This paper aims to examine whether ownership concentration and earnings management affect the stock market liquidity of Malaysian firms. Design/methodology/approach This study uses a sample of 2,020 yearly firm observations in Bursa Malaysia over the period 2009-2012. The ordinary least square regression is used to examine the relationships. The study undertakes a sensitivity test by regressing the main study variables by using different measurements. Another robustness test is then used, where a regression based on the change in variables and a one-year lag of the independent variables are used. Furthermore, to alleviate the concern of possible endogeneity, the simultaneity and reverse causality are checked using the lag of the dependent variable, fixed effect regression, two-stage least squares using the instrumental variables and the generalized method of moments using instrumental variables analysis. Findings The study finds that firms with a high level of ownership concentration have discrepancies in information between informed and uninformed traders, which impair the stock market liquidity. In addition, this study finds that firms with high earnings management experience greater liquidity. A possible explanation for this is that firms might manage earnings to convey private information to enhance the information content of the earnings. Overall, the evidence suggests that manipulating earnings signals information informatively, particularly in a country with a higher level of ownership concentration and a higher likelihood of expropriating minority shareholders. Originality/value This study enriches the limited empirical research devoted to the impact of earnings management and ownership concentration on stock market liquidity especially in the context of emerging economies. The findings of this study are robust to alternative liquidity measurements, to alternative estimation methods, and to endogeneity bias.

Purpose The purpose of this paper is to investigate the effect of female members in boards of directors on asymmetric information in the French stock market. Design/methodology/approach The authors use two proxies for asymmetric information: the idiosyncratic volatility and the bid-ask spread. This study is conducted on all listed firms in the SBF 120 index between 2002 and 2012. Findings Results show that gender diversity in boardrooms has a negative effect on the level of private information in stock markets and reduces the bid-ask spread. However, these effects are significant in family-controlled firms: female inside directors significantly increase the idiosyncratic volatility and the bid-ask spread, while female independent directors decrease both proxies for stock market liquidity. Research limitations/implications Our empirical findings contribute to the current debate on the benefits of gender diversity on corporate boards from the market perspective. It shows that, under specific conditions, financial markets could be receptive to the presence of female directors in boardrooms. Practical implications Practitioners and policymakers advocate the benefits of gender diversity on corporate boards. This paper shows that when the protection of minority shareholders is poor, the stock market is receptive to the presence of women independent directors, only in family controlled firms. This is a further argument that could help women to overcome glass-ceiling barriers they usually face to achieve top management positions. Originality/value This paper provides support for the increased attention paid to gender-diverse boards. It addresses the market sensitivity toward the presence of women members in French boardrooms and their positions. This is the first paper, to the best of our knowledge, to address how appointing women to different positions in the boardroom could provide signals to investors in the presence of asymmetric information. French firms are mostly family controlled. Thus, the findings bring valuable information of the impact of board diversity on the stock market considering family and nonfamily firms.
