投资者结构模式变迁与市场流动性风险

本文研究了市场流动性风险与投资者结构模式之间的关系。随着机构投资者的不断发展壮大,我国投资者结构模式发生了重要转变,然而新的投资者结构模式下,市场流动性的波动结构是否有所不同？本文以流动性水平变化率为研究对象,构建了包含虚拟变量的TGARCH模型对其波动方程进行拟合,研究发现：机构投资者壮大后市场流动性风险显著降低;机构占主导后市场流动性风险受新信息的影响权重较之前增大,而旧有信息对流动性风险的影响相比以前减小。     

融资融券交易提高了市场流动性吗

运用SVAR模型检验2010年3月31日至2019年11月7日融资买空和融券卖空交易对上海和深圳A股市场流动性的同期影响和长期影响,并进一步分析不同标的股票范围和不同的市场状态下融资买空和融券卖空交易对沪深A股市场流动性的影响。研究结果表明:融资买空和融券卖空交易对上海和深圳A股市场流动性的同期和长期影响都是显著为正的,且对上海A股市场流动性的正向影响大于深圳A股市场;融资买空交易对市场流动性的正向影响大于融券卖空交易,这是因为融资买空交易规模远远大于融券卖空交易规模;融资买空交易与融券卖空交易对市场流动性的同期和长期影响并不随着标的股票范围的扩大而增加,而是与二者交易规模有关;熊市时融资买空交易对市场流动性的长期影响大于牛市。

流动性与资产定价:基于中国A股市场的实证研究

Acharya and Pedersen（2005）提出的考虑流动性风险的资本资产定价模型（即LCAPM）认为，证券的期望收益取决于其期望流动性成本、其流动性成本和市场流动性成本与市场收益的协方差。以及其收益和市场收益与市场流动性成本的协方差。本文用中国股市的收益数据对Acharya and Pedersen（2005）的LCAPM进行了实证检验。结果发现，在各种不同的市场特征下，基于流动性的CAPM模型更好的拟舍了资产收益，不同的模型设定使得结论相对稳健。这说明流动性水平和流动性风对我国股市的资产定价有重要影响，在我国证券市场资产评估中要考虑流动性的重要性。

“次贷危机”背景下沪港股市溢出效应研究

文章对美国"次贷危机"爆发后沪港股票市场在波动性与流动性方面的溢出效应进行实证研究。研究结果表明,随着次贷危机的蔓延与深化,沪港股市的波动性溢出与流动性溢出呈现不同特征。在危机初期,仅存在上海股市流动性单向溢出到香港市场;在危机后期,香港市场的流动性与波动性均单向溢出到上海市场。     

企业价值评估中流动性溢价探讨

正一、流动性与流动性溢价大到宏观经济的货币供需,小到企业和个人的资金运转,都涉及到流动性的影响和渗透。流动性溢价理论产生于证券交易市场,是流动性影响资产定价领域的一种重要表现形式。(一)流动性的涵义针对不同经济层面,流动性的涵义有所区别。宏观经济中的流动性是整个经济体系中货币的总投放量;资本市场中的流动性为参与交易的资金相对于交易资产的供给程度;个别资产的流动性则是指资产买卖的难易程度。有效市场假说认为资本市场中的价格已经包含了影响资产基本价值的所有信     

What drives the liquidity premium in the Chinese stock market?

This paper examines the dynamics of the liquidity premium in the Chinese stock market by adopting a multivariate decomposition approach to measure the individual contributions of various driving forces of the premium (such as firm size, idiosyncratic volatility, and market liquidity betas). By employing a wide range of liquidity measures, we show that liquidity premium is generally significant in the Chinese stock market. Furthermore, this premium is increasing in recent years starting from 2011; this observation is different from the United States market, in which the premium has declined over the years. Moreover, the multivariate decomposition approach highlights several asset pricing factors as the main driving forces of the premium. Based on the Amihud liquidity measure, the decomposition approach indicates that the size factor contributes 45–65% to the liquidity premium. However, the measure based on turnover suggests that idiosyncratic volatility accounts for at least 60% of the liquidity premium. In contrast, the global market liquidity beta does not significantly contribute to the premium. However, there is some evidence that the local market liquidity beta has become more significant in its impact on the premium during the period from 2011 to 2015. Our results imply that the findings on the liquidity premium in the Chinese stock market could be sensitive to the liquidity measure used and period of analysis.     

Mutual Fund＇s Behavior on Stock Liquidity： Empirical Results from Chinese Security Market

This paper studies the relationship between fund investment and market liquidity by using Chinese security market data. The results show that, among several measures of market liquidity, the indexes based on volume, such as turnover and market depth, have a deeper impact on fund investment decision. Furthermore, the relationship between security liquidity and fund investment varies when market status is taken into account. On the other hand, fund investments have a negative effect on security liquidity measured by market width, while have a positive effect on other liquidity measures. The authors attribute the results to herding behavior of fund investment.     

我国沪深证券市场流动性实证研究

流动性是一个市场的生命力所在。一个流动性好的市场才能很好的满足投资者的交易需求,减少投资者流动性风险是市场应该提供的功能之一。随着我国资本市场的逐步发展和成熟,投资者越来越注意到市场流动性的重要性。如何准确的界定流动性,如何用一系列的指标体系,来衡量一个市场的流动性,是理论界和市场投资者都很关注的问题。国内外对流动性的研究也很多,本文在借鉴前人研究成果的基础上,提出了自己对于流动性测量的一种观点,通过建立一个基于收益率和相对交易量基础之上的模型,来探讨关于市场流动性的问题。     

Retail investors’ trading and stock market liquidity

The paper investigates the relation between retail investors’ participation in trading and aggregate stock market liquidity. The findings show a positive and significant relation between retail investors’ trading and stock market liquidity. Examination of the determinants of retail investors’ trading reveals that, on average, retail investors with more diversified trading activity tend to trade when liquidity is higher, the frequency of their arrival to the market is not affected by the level of liquidity, and retail investors are willing to trade at a lower liquidity level as sellers than as buyers. Moreover, retail investors’ trading does not create price noise at the aggregate market level. Overall, the evidence suggests that retail investors contribute to market quality.     

On illiquidity of an emerging sovereign bond market

This study offers an analysis of a sovereign bond market in an emerging country, Turkey, and its illiquidity. We employ the Nelson-Siegel model to generate a term structure for interest rates directly from daily bond price quotes in the Turkish market. We take the noise measure, which is the byproduct of term structure estimation, as a proxy for market-wide illiquidity. Our results show that this noise measure can capture the illiquidity in the Turkish fixed-income market from global financial turbulence as well as local dynamics. Inflation uncertainty and sentiment are the major macro drivers of liquidity crunches. It has also become clear that liquidity in an emerging market such as Turkey in the aftermath of the 2008 crisis has been driven by global forces, however, since 2013 local factors have taken over. This apparent decoupling in liquidity between a major emerging market and global markets followed the approaching end of quantitative easing and a rise in economic turbulence in the country since then.     

Do voluntary disclosures of bad news improve liquidity?

Can managers improve market liquidity and lower the cost of capital by providing voluntary earnings guidance? This study examines the impact of profit warnings on market liquidity and finds that voluntary disclosure of bad news actually improves market liquidity. By conducting an empirical study over the period 1995–2010 on NYSE, NASDAQ and AMEX listed firms, we find that firms that issue profit warnings show enhanced market liquidity during the post-announcement period. We show that profit warnings reduce information asymmetry and lower bid-ask spreads and increase trading volumes. These results are invariant to daily (short run) and monthly (long run) data after controlling for firm specific attributes. The results have major corporate policy implications. By voluntarily disclosing negative earnings guidance by managers, firms will experience significant improvement in market liquidity, thereby lowering the cost of capital. Our results are even more profound for firms that release bad news with extremely negative stock market impact. In other words, voluntary disclosure of bad news is good for market liquidity.
