Asset Liquidity and Stock Liquidity: International Evidence

This study examines the relationship between asset liquidity and stock liquidity across 47 countries. In support of the valuation uncertainty hypothesis, we find that firms with greater asset liquidity on average have higher stock liquidity. More importantly, our study shows that asset liquidity plays a more significant role in resolving valuation uncertainty in countries with poor information environment. For example, we find that the asset–stock liquidity relationship is stronger in countries with poor accounting standards. We further find evidence that after the adoption of IFRS, the improved accounting information environment results in a weaker asset–stock liquidity relation, but only in countries with a strong legal regime. Finally, our study shows that the positive asset–stock liquidity relationship may be attributed to transparency and/or liquidity reasons.     

股指成份股调整与股价崩盘风险:基于一项准自然实验的证据

本文考察了入选沪深300指数成份股对该公司未来股价崩盘风险的影响。为缓解内生性问题,本文利用中国特有的备选股制度所提供的准自然实验机会,以备选股作为对照组,采用双重差分模型进行了实证检验。分析结果表明,相比备选股,公司在入选成为股指成份股之后,其股价崩盘风险显著上升。进一步的路径检验发现,分析师乐观预测偏差及分析师跟随在其间起到了部分中介效应。本研究不但有助于更好地理解股价崩盘风险动因和股指成份股调整的经济后果,也为监管部门加强分析师监管、完善成份股调整制度提供了决策参考。     

Liquidity,Skewness and Stock Returns: Evidence from Chinese Stock Market

In this paper, a capital asset pricing model (CAPM) incorporating liquidity and skewness factors is proposed and tested by using the Chinese stock market data. The empirical results indicate that, under various market conditions, the liquidity-adjusted three-moment CAPM provides a better fit to the realized returns of various stock portfolios. Overall, this research reveals that illiquidity cost, liquidity risk and as well as skewness have important impacts on asset pricing in the Chinese stock market.     

Technical Analysis,Investment Psychology,and Liquidity Provision: Evidence from the Taiwan Stock Market

We set out to empirically identify the effects on technical signals attributable to psychological biases, adopting a set of specific liquidity provision proxies for a sample of firms listed on the Taiwan Stock Exchange. The main findings of our empirical analysis are that the "disposition," "information cascade," and "anchoring" effects each have significant impacts on trading signals. Our results should help to shed further light on the asymmetric market responses to technical buy and sell signals, while also providing some potential clarification of the different attitudes of traders toward big-cap and small-cap firms.     

Information Disclosure and Stock Liquidity: Evidence from Borsa Italiana

This article examines the effect of increased corporate information disclosure on stock liquidity. Using the adoption of International Financial Reporting Standards (IFRS) in Italy as a natural experiment we extend previous work examining the effect on one measure of liquidity—bid‐ask spreads—to others, specifically depth and the price impact of transactions (or effective bid‐ask spreads). Consistent with previous research we find that bid‐ask spreads of stocks decline following the introduction of IFRS, which implies that stock liquidity increases for small traders. However, we also provide evidence that depth at the best quotes declines, which challenges the proposition that liquidity increases for large trades following an increase in disclosure. In additional tests, we find that effective bid‐ask spreads of block trades also decline following the introduction of IFRS. Overall, this evidence confirms that stock liquidity for both small and large trades increases following an increase in corporate information disclosure.     

Liquidity and Liquidation: Evidence from Real Estate Investment Trusts

This study provides evidence that highly leveraged owner-managed properties liquidated assets during the commercial real estate decline of the late 1980s, and that this provided buying opportunities for better capitalized buyers. The analysis documents significant financial distress costs for highly leveraged firms during an industry-wide downturn and shows that these costs are particularly large for owner-managed firms.     

货币政策与股票市场流动性风险——来自中国股票市场的经验证据

本文首先应用模型刻划了我国股票市场流动性变化特征,并以非预期流动性度量流动性风险:其次从货币供应量和利率两个方面,应用VAR模型分析了我国货币政策与流动性风险的关系.研究发现M2的变化对流动性风险影响最大,准M2、M1的变化次之,M0、准M1的变化最小;流动性风险对准Ml变化影响最大,对M1、M2变化次之,对准M2和M0变化几乎没有影响.利率与流动性风险相互影响很小.     

Liquidity Provision and Noise Trading: Evidence from the Investment Dartboard Column

How does increased noise trading affect market liquidity and trading costs? We use The Wall Street Journal's “Investment Dartboard” column, which stimulates noise trading, as a natural experiment to evaluate models of the bid-ask spread. We find that substantial increases in trading volume and significant but temporary abnormal returns occur when analysts recommend stocks in this column, especially when recommendations come from analysts with successful contest track records. We also find an increase in liquidity and a decrease in the adverse selection component of the bid-ask spread.     

Liquidity Dynamics Around Jumps: The Evidence from the Warsaw Stock Exchange

The aim of our study is to examine the dynamics of trading volume and the number of trades around jumps detected in intraday stock returns. We detect jumps in equally spaced 10-minute returns for most liquid stocks quoted on the Warsaw Stock Exchange within one-year sample period. We match jumps with macroeconomic and firm specific news. We find that only the minority of jumps is associated with public information releases, whereas the majority of them is motivated by liquidity shocks observed in the spreads, volume, and the number of trades. Our findings show that jumps are related to the inability of the market to absorb new and big orders. Liquidity shocks in volatility, volume, and quoted spread are the key drivers accompanying the occurrence of the jumps. Finally, the introduction of a faster and more efficient trading system improves the liquidity by increasing the depth of the market.     

Debt,Liquidity Constraints,and Corporate Investment: Evidence from Panel Data

This paper presents evidence supporting the theory that problems of asymmetric information in debt markets affect financially unhealthy firms' ability to obtain outside finance and, consequently, their allocation of real investment expenditure over time. I test this hypothesis by estimating the Euler equation of an optimizing model of investment. Including the effect of a debt constraint greatly improves the Euler equation's performance in comparison to the standard specification. When the sample is split on the basis of two measures of financial distress, the standard Euler equation fits well for the a priori unconstrained groups, but is rejected for the others.     

Information Asymmetry and Corporate Liquidity Management: Evidence from Real Estate Investment Trusts

We examine the impact of information asymmetry on a firm??s choice between cash and credit lines for corporate liquidity management using a panel data set from real estate investment trusts (REITs). Information asymmetry, as measured by analyst forecast error and dispersion, is negatively related to the use of lines of credit. Specifically, firms with more severe information asymmetry are less likely to have access to bank credit lines. Concurrently, more transparent firms are more likely to utilize bank credit lines as opposed to cash for liquidity management. The results are robust to alternative information asymmetry proxies and specifications. These findings suggest that information asymmetry plays an important role in corporate liquidity management.     

股票市场开放与企业投资效率——基于“沪港通”的准自然实验

资本市场的持续对外开放是党的十九大强调的重要举措。本文基于沪港通开通这一准自然实验,检验了股票市场开放对企业投资效率的影响。结果发现:沪港通的开启促进了标的公司投资效率的提高,这一影响主要体现在信息环境不透明、治理水平低的公司;机制分析发现,沪港通开启后,公司信息质量的提高和分析师预测准确度的增加是股票市场开放影响标的公司投资效率的重要渠道;最终标的公司在沪港通开通后经营业绩也得到提升。本文结论表明,股票市场开放改善了公司的投资效率,提高了对实体经济的服务能力,这对党的十九大提出的“深化资本市场对外开放”和“金融服务实体经济”系列改革有重要启示。

Stock Price Distributions and News: Evidence from Index Options

We estimate the shape of the distribution of stock prices using data from options on the underlying asset, and test whether this distribution is distorted in a systematic manner each time a particular news event occurs. In particular we look at the response of the FTSE100 index to market wide announcements of key macroeconomic indicators and policy variables. We show that the whole distribution of stock prices can be distorted on an event day. The shift in distributional shape happens whether the event is characterized as an announcement occurrence or as a measured surprise. We find that larger surprises have proportionately greater impact, and that higher moments are more sensitive to events however characterised.     

Stock Splits and Liquidity: The Case of the Nasdaq-100 Index Tracking Stock

In an attempt to disentangle the signaling effect from the liquidity effect of stock splits, I examine the liquidity changes following the two‐for‐one split of the Nasdaq‐100 Index Tracking Stock. Since there can be no signaling with an index stock split, any difference between pre‐ and postsplit trading may be driven by liquidity but not signaling effects. I find that though the postsplit relative bid‐ask spread is higher and daily turnover is unchanged, the frequency, share volume, and dollar‐volume of small trades all increased after the split, indicating that the split improved liquidity for small trade‐sizes.     

The Effects of Trading Methods on Volatility and Liquidity: Evidence from the Taiwan Stock Exchange

This study contrasts the call and continuous auction methods using Taiwan Stock Exchange data. Volatility under the call market method is approximately one-half of that under the continuous auction method. The call market method is more effective in reducing the volatility of high-volume stocks than low-volume stocks. This contradicts conventional wisdom which suggests that the call market method is superior for thinly traded stocks, while the continuous auction method is preferred for heavily traded stocks. The call market method does not impair liquidity and price discovery. The call market appears more efficient than in the continuous auction market.     

股指成分股调整与企业投资效率

为了研究股指成分股调整对投资效率的影响,把2007年6月至2019年6月沪深300指数共25次调整的成分股作为处理组,以同期每次调整公布的备选股作为控制组,构建双重差分模型。研究结果表明,指数调整之后,与备选股公司相比被调入为成分股的公司的投资效率显著提升。进一步的异质性分析发现,成分股调整对企业投资效率的影响在非国际四大会计师事务所审计和非国企的样本组里更加显著。     

估算中国的IFDI和OFDI——来自“避税天堂”与返程投资的证据

本文梳理了现有文献对离岸金融中心导致的直接投资头寸统计偏差进行修正的方法,详细比较了直接投资头寸数据集的优劣差异,并以CDIS宏观数据集为基础,引入Orbis微观企业数据库作为重要补充,对直接投资的动机按避税目的和境外上市目的进行区分,以此估算我国的IFDI和OFDI存量。结果表明:(1)估算后,来自离岸金融中心的IFDI调减1.1万亿美元,其中超过80%是出于避税目的进行的返程投资;(2)考虑VIE架构境外上市企业的影响后,返程投资占比增长至近37%,规模约1万亿美元,其中VIE架构境外上市企业贡献了16%;(3)我国对外投资存在经过“避税天堂”进行中转的现象,其中最终投向英属维尔京群岛的OFDI存量约占1/4,是我国实际OFDI的最主要投向地。
