What determines stock liquidity in Australia?

Using an index of corporate governance quality (CGQ), we provide the first robust evidence of the determinants of stock liquidity in Australia. We assume that CGQ affects stock liquidity because effective governance decreases information asymmetries between insiders (e.g. managers) and outsiders (e.g. investors), as well as among outsiders, by improving information transparency of a firm. Consistent with agency theory, this study, using 435 large capitalization firms over the period from 2001 to 2008, finds a significant positive relationship between CGQ and stock liquidity, suggesting that better governed firms have a higher level of stock liquidity. These findings are robust to alternative proxies of CGQ, stock liquidity and endogeneity bias.     

Liquidity commonality in order-driven trading: evidence from the Athens Stock Exchange

We examine the presence of liquidity commonality in the order-driven Athens Stock Exchange (ASE). Unlike the majority of liquidity commonality studies that focus on the bid–ask spread, our analysis extends deeper in the Limit Order Book, providing insight on the price impact of both small and large trades. We utilize a 6-month FTSE/ATHEX-20 intraday data set to estimate the liquidity factor model of Chordia et al. (2000). To this end, we conduct single-equation analysis as well as panel data analysis with the use of two-way clustered errors, correcting for simultaneous firm and time correlations. Moreover, we apply standard principal component analysis on stock liquidities to extract the marketwide liquidity component. We find that liquidity commonality is low at the bid–ask spread, whereas it increases deeper in the book; consequently, large traders face liquidity risks associated with both individual stock and marketwide illiquidity. Moreover, our empirical evidence hints that liquidity commonality is asynchronous, suggesting that the ASE trading process includes various levels of information speed. Our analysis contributes to the understanding of liquidity commonality in order-driven trading, especially in emerging markets like the ASE where trading activity is limited and information speed is low.     

流动性与资产定价:基于我国股市资产换手率与预期收益的实证研究

流动性与资产定价是目前金融研究的热点之一 (O’Hara,2 0 0 3 )。本文通过检验交易频率零假设和交易成本备择假设 ,深入分析我国股市流动性与资产定价的理论与经验关系 ,发现 :我国股市存在显著的流动性溢价 ,换手率低、交易成本高且流动性小的资产具有较高的预期收益 ;产生流动性溢价的原因是交易成本而不是交易频率 ;与国外股市相似 ,小企业收益率高于大企业 ,价值股收益率高于成长股。因此 ,我国股市并非令人无法捉摸 ,流动性、规模和价值效应都是资产定价的因素     

Sleeping with the enemy: The perils of having the government on(the)board

We study the causal effect of unsought political connections on firm value. To address concerns of potential endogeneity and sample-selection bias we exploit the nationalization of Argentina's pension system, a unique natural experiment yielding exogenous variation in new political connections. We find unsought political connections to have a large negative effect on the value of newly connected firms. Yet this result only materializes when, in addition to becoming a shareholder, the government also obtains the right to appoint directors. Decreased stock liquidity or higher stock volatility do not explain this result, suggesting a channel that decreases expected cash flows to shareholders.

Do financial distress and liquidity crises affect value and size premiums?

This study investigates the impact of liquidity crises on the relationship between stock (value and size) premiums and default risk in the US market. It first examines whether financial distress can explain value and size premiums, and then, subsequently, aims to determine whether liquidity crises increase the risk of value and size premium investment strategies. The study employs a time-varying approach and a sample of US stock returns for the period between January 1982 and March 2011, a period which includes the current liquidity crisis, so as to examine the relationship between default risk, liquidity crises and value and size premiums. The findings indicate that the default premium has explanatory power for value and size premiums, which affect firms with different characteristics. We also find that liquidity crises may actually increase the risks related to size and value premium strategies.     

Daily happiness and stock returns: The case of Chinese company listed in the United States

Existing literature exclusively focuses on the association between local investor sentiment and local stock market performance. In this paper, we investigate the contemporaneous and the lead-lag relationship between local daily happiness sentiment extracted from Twitter and stock returns of cross-listed companies, i.e., the Chinese companies listed in the United States. The empirical results show that: 1) by respectively controlling for the firm capitalization, liquidity and volatility, there exists the largest skewness on the Most-happiness subgroup. (2) There exist bi-directional relationships between daily happiness sentiment and market variables, i.e., the stock return, range-based volatility and excess trading volume. (3) There are significantly positive stock returns, higher excess trading volume and higher range-based volatility around the daily happiness sentiment spike days. These findings not only suggest that there exists significant interdependence between online activities and stock market dynamics, but also provide evidence for the existence of “home bias”.     

Impact of government policy responses of COVID-19 pandemic on stock market liquidity for Australian companies

This study investigates the impact of government policy responses of COVID-19 pandemic on stock market liquidity for listed Australian companies and for 11 different industries separately. A quantitative deductive approach is used for a sample of 1,452 companies with a total of 292,164 firm-day observations over a period from January 25, 2020 to December 31, 2020 during the outbreak of COVID-19. Univariate and multivariate (two-way cluster-robust panel regression) analysis were conducted. Data were collected from the Oxford COVID-19 Government Response Tracker, Worldmeter, Refinitiv Workspace and Datastream. Our findings indicate that the influences of the six out of seven stringency policy responses reduced Australian equity market liquidity. However, public information campaigns enhanced market liquidity and hence trading activity. Among the 11 industries, our analysis shows that the non-pharmaceutical interventions by the Australian government have significant and positive effects on four industries: Consumer non-cyclicals, healthcare, financial and technology. However, the worse effects were depicted in the industrial (transportation) and energy industries. This study is important for investors, policymakers and regulators to understand the diverse effects of government policy responses of COVID-19 on stock market liquidity to enhance financial stability. Moreover, understanding this effect is particularly important to decision-makers such as portfolio and fund managers to manage their portfolios and trading activities during extreme turbulence times, such as COVID-19. Unlike previous studies that focus on country analysis, this study examines on firm basis the impact of government interventions on stock market liquidity in a well developed Australian stock market.     

LIQUIDITY RISK AND CORPORATE HEDGING WITH FUTURES

This paper examines the hedging behaviour of a value‐maximizing firm that exists for two periods. The firm faces uncertain income and is subject to tax asymmetries with no loss‐offset provisions. The firm has access to unbiased futures contracts in each period for hedging purposes. We impose a liquidity constraint on the firm. Specifically, whenever the net interim loss due to its first‐period futures position exceeds a predetermined threshold level, the firm is forced to terminate its risk management program and, therefore, is prohibited from trading the futures contracts in the second period. We show that the liquidity‐constrained firm optimally adopts a full‐hedge via its second‐period futures position to minimize the extent of the income risk and an under‐hedge via its first‐period futures position to limit the degree of the liquidity risk.     

公司控制权、资本流动性与并购绩效*——基于交互视角的中国上市公司股权收购的研究

现有文献分别考察了公司内部治理机制和外部资本市场对并购绩效的影响,甚少考虑外部资本市场与内部治理特征内生性的影响,这会使研究结论产生偏差。本文将上述两者结合起来,在交互的视角下,首先运用夏普里（Shapley）值分解法分析了控制权与流动性各自对并购绩效的贡献,进一步分析了控制权与流动性之间的相互影响,并设计了分位数分组回归模型,研究在流动性调整下控制权的并购绩效效应。本文研究表明,流动性对公司控制权的并购绩效产生了比较明显的调整,货币市场流动性高时控制权并购绩效低;股票市场流动性高时控制权并购绩效显著;而个股流动性对控制权的并购绩效调整不明显。

The effects of cash flow and size on the investment decisions of ICT firms: A dynamic approach

This paper examines one of the fastest growing industries in our world today, the ICT industry. We assess the sensitivity of a firm’s investment to a set of financial determinants, by developing a flexible adjustment dynamic model. In particular, we examine the degree to which a firm’s liquidity influences firm investment and whether firm size and firm specialization have any additional implications. Moreover, the effect of the dot-com burst is also considered. For a panel of ICT and non-ICT US companies listed on the NASDAQ stock exchange, the results reveal the following: (1) all firms are sensitive to the availability of internal funds; (2) investment intensity decreases with firm size; (3) and leverage negatively affects investment for ICT firms.     

Determinants of corporate default risk in China: The role of financial constraints

Corporate default risk can affect financial stability and the macroeconomy. However, the determinants of corporate default risk in China are not well defined in the literature. We address this issue by using a rich credit event dataset of 981 Chinese listed firms over the period 1998–2013 and study the factors that affect default risk. We demonstrate that leverage, liquidity, firm size are the key firm-specific factors in determining default risk in China, along with macroeconomic factors like interest rate and stock return. Moreover, ‘Too big to fail’ only applies to non-SOEs, as default risk of SOEs is not affected by the firm size. We further find that high liquidity fails to reduce firms default risk, because small-sized firms which are financially constrained have limited cash to prevent financial distress, whereas large firms with greater cash holdings are able to mitigate their default risk as they are unconstrained.     

股票流动性与企业创新：促进还是抑制——企业异质性视角

基于2010—2017年我国沪深A股1281家上市公司数据,从企业异质性视角分析股票流动性对企业创新的影响。结果发现：总体来看,股票流动性会抑制企业创新,而且对后期抑制作用更大;企业规模和行业特征是影响“股票流动性-企业创新”关系的重要因素,即股票流动性对大型企业和传统行业企业创新具有促进作用,而对中小型企业和高科技行业企业具有抑制作用。进一步机制研究显示,稳定型机构投资者和交易型机构投资者在股票流动性与企业创新间起双中介作用,虽然股票流动性对二者的作用方向相反,但最终都会导致企业创新水平下降。     

Asset Markets and Endogenous Liquidity

In financial markets characterized by imperfect depth, speculative trading will have transitory effects on the market price as market makers must be compensated for the risk of holding the asset. The number of people providing liquidity to a market will generally be endogenously determined by the quantity of liquidity demanded. This paper looks for evidence of endogenous liquidity provision in several international stock and bond markets. Evidence shows strong support for these speculative dynamics in the stock markets. The evidence for these dynamics is less striking with fixed‐income prices, consistent with the less speculative nature of these markets.     

Effect Of Liquidity On Firms' R&D Spending

The effect of firms financial condition on their R&D investment is explored using a relatively long panel data set for five high-technology industries. We find that financial condition, whether measured as cash flow, the stock of liquid assets or the ratio of liquid assets to current liabilities, does affect the R&D spending of small firms. The effect persists after controlling for unobserved permanent firm effects, and the pattern of significance of lagged effects supports the interpretation of causality running from liquidity to R&D. For larger firms, there is no evidence of such an effect. Using these data, we cannot say whether the absence of an effect in larger firms results from better access to capital markets or from higher adjustment costs in R&D.     

股票流动性与企业创新：促进还是抑制——企业异质性视角

基于2010—2017年我国沪深A股1281家上市公司数据，从企业异质性视角分析股票流动性对企业创新的影响。结果发现：总体来看，股票流动性会抑制企业创新，而且对后期抑制作用更大；企业规模和行业特征是影响“股票流动性-企业创新”关系的重要因素，即股票流动性对大型企业和传统行业企业创新具有促进作用，而对中小型企业和高科技行业企业具有抑制作用。进一步机制研究显示，稳定型机构投资者和交易型机构投资者在股票流动性与企业创新间起双中介作用，虽然股票流动性对二者的作用方向相反，但最终都会导致企业创新水平下降。

Momentum or market? Determinants of large stock price changes in an emerging market

The aim of this study is to investigate the determinants of large price changes in Turkey. We also provide additional evidence on determinants of large price changes in different macroeconomic environments, specifically on the pre-crisis and post-crisis periods. Using recurrent event analysis with stratified observations and frailty effects, our findings suggest that momentum has a significant impact on large price changes during both pre-crisis and post-crisis periods. However, the impact of market is more significant on the estimation of large price declines in the pre-crisis period and of large price increases in the post-crisis period. Additional findings suggest that liquidity and market-to-book ratio have positive, firm size has a negative impact on likelihood of large price changes regardless of the direction of the stock price change and macroeconomic environment. Findings of this study provide new insights into the understanding of large price changes in an emerging market.     

Financial Constraints and Investment Decisions

In what follows we show that liquidity constraints can affect a firm's investment even when the constraints are not currently effective. This happens when, at any given time, the firm believes that internal finance is likely to become a constraint in the future. In these circumstances, the value of the firm becomes a non‐monotonic functional form of the fundamental. Thus, in a dynamic setting, the potential barrier to internal liquidity expansion exerts a global effect on the firm's investment policy, lowering its desired investment profile (Classification JEL: E22, E51 ).
