中国股票市场流动性研究

股票市场的流动性是一个整体的概念，我们必须从不同的角度进行综合思考，才能得到对一个市场流动性的全面认识。从比较的视角考察中国股票市场，我们发现其流动性远远无法与发达国家相比。中国股票市场在提升流动性方面还任重而道远。     

中国股票市场流动性特征及其影响因素

本文根据买卖价差、有效价差、价格冲击指数和流动性指数四个指标对中国股市流动性进行比较分析。从历史发展来看,深沪两市的流动性不断提高,上海股市在流动性指数上好于深圳市场,在价格冲击指数及相对买卖价差上,深圳市场流动性高于上海市场;与国际主要证券市场相比,中国股市流动性在价差类指标上处于较好的水平,但价格冲击指数高于全球平均水平。     

中国股票市场流动性与回报率研究——基于AM模型的上证领先指数实证分析

流动性是进行金融资产定价的核心所在,缺乏流动性的金融资产,其价值必将贬值甚至失去存在的价值.文章借鉴国外学者对股票市场的流动性与回报率的研究成果,运用Amihud&Mcndelson模型原理,选取上海证券交易所1997年1月1日至2009年12月31日的交易资料,使用以价格冲击为主的流动性指标,实证检验了中国证券市场流动性风险与股票回报率的相关关系,并找出中国股票市场中流动性对股票定价的影响.     

中国股市流动性风险测度研究

引言 证券的流动性是指证券的变现能力。从证券流动性的概念来看，其本质是指在现在价位不变的情况下或在价位波动较小的情况下，能够卖出证券的数量或金额，如果能够卖出的数量或金额较大则该证券的流动性较好。从另外一个角度来看，流动性还指在现在价位不变或在价位波动较小……     

股指期货对股票市场流动性影响的实证分析

借助沪深300指数日交易数据,用成交量、相对价格、收益率波动率作为度量股票市场流动性指标,运用实证分析法分析了股指期货的推出对股票现货市场流动性的影响。研究发现,股指期货上市初期对股票现货市场流动性产生资金挤出效应,短期内降低了现货市场的流动性。从长期来看,由于股指期货具有吸引场外资金效应,吸引了大量的场外资金入市,股票现货市场流动性均呈逐步增强的趋势。     

货币政策对股票市场流动性的影响研究——基于我国股票市场2003年~2013年的实证分析

我国股票市场历经20多年发展取得卓越成就,在发展历程中长期受到政府政策的影响,尤其是货币政策,对我国股票市场发展的影响不容忽视。本文采用我国股票市场2003年1月²013年6月的月度数据,构建VAR模型,通过脉冲响应分析研究了货币政策对我国股票市场流动性的影响。实证结果显示,货币供应量M0、M1、M2对股票市场非流动性具有负向冲击,利率R对股票市场非流动性具有正向冲击;货币供应量M2的冲击力度最大,M0最小;货币供应量M1的影响周期最长,M0最短。最后在研究基础上提出政策建议。

中国和印度股票市场的比较研究

中国和印度都是人口众多、低收入的发展中国家,本文主要是对中印股票市场的宏观环境以及股票市场的各自特点进行对比分析,以期从印度股票市场的发展中得出一些经验,为我国股市的良性、健康发展提供一定政策建议     

货币政策、流动性溢价与股票市场波动

国内外大量研究表明货币政策与股票市场的波动有着千丝万缕的联系。本文基于固浮利差对货币政策进行了分解,采用事件研究法,分析了货币政策对股票市场波动的影响,并探索了货币政策对股票市场波动影响的传导途径。实证结果表明:第一,货币政策对股票市场波动率有负向的影响;第二,未预期的货币政策对股票市场收益率的变化有显著的负向影响;第三,未预期的货币政策对流动性资产的流动性溢价有显著正向影响;第四,准备金和政府债券的流动性溢价在未预期的货币政策对股票市场收益率的影响关系中具有中介效应。     

产品市场势力、公司治理与股票市场流动性

本文实证研究了我国股票市场的流动性问题。结果表明,产品市场势力能够促进信息传递,提高股票的流动性。这种影响即使控制了公司治理因素依然显著,同时随着信息不对称程度的提高而更为明显。另外,在对股票流动性的影响上,产品市场势力与董事会规模、高管薪酬激励之间存在替代关系。同时,股权分散能增强产品市场势力的影响,但是产品市场势力会削弱股权分散的积极作用。     

对我国股市流动性问题的几点思考

本文提出换手率指标不能用来衡量股市流动性,并按国际市场和学术界对流动性的界定对我国股市流动性进行了分析,得出我国股市流动性在国际上处于较低水平;并分析了造成这种状况的原因主要有市场结构、交易机制和监管环境等方面;最后提出了改善我国股市流动性的一些对策。     

Privatization and stock market liquidity

This paper shows that share issue privatization (SIP) is a major source of domestic stock market liquidity in 19 developed economies. Particularly, privatization IPOs have a negative effect on the price impact – measured by the ratio of the absolute return on the market index to turnover. This result is robust to the inclusion of controls for other observable and unobservable factors, having also considered the endogenous nature of the decision to privatize.     

Exchange trading rules and stock market liquidity

We examine stock exchange trading rules for market manipulation, insider trading, and broker–agency conflict, across countries and over time, in 42 stock exchanges around the world. Some stock exchanges have extremely detailed rules that explicitly prohibit specific manipulative practices, but others use less precise and broadly framed rules. We create new indices for market manipulation, insider trading, and broker–agency conflict based on the specific provisions in the trading rules of each stock exchange. We show that differences in exchange trading rules, over time and across markets, significantly affect liquidity.     

如何看待中国股市前景

我第一次来中国是2003年,之前很关注欧洲的市场.我的基金主要投资英国的证券.从2004年开始,我们把一部分资金转到中国市场,但投资的数额很少,只有几百万美元.以后到中国来,跟中国的企业进行接触,并开始管理资金.我来过中国几次,中国的发展日新月异,我想在结束投资生涯之前,要运作一支专门做中国市场投资的基金.如果能够做到这点,等我退休时会感到欣慰.现在我在香港管理一支纯中国市场基金.     

An examination of the effect of stock market liquidity on bank market power

This paper investigates the spillover effects of aggregate stock market liquidity on bank market power using a sample of 44 countries and 7297 individual banks from 1999 to 2014. Country-level and bank-level analysis shows that enhancement in stock market liquidity strengthens the market power of the banking sector. This relationship is more pronounced in developed market countries and in countries with common law origin, which offer better investor protection. To the best of our knowledge, this is the first paper to provide comprehensive empirical evidence of the complementary relationship between banks and stock markets, providing important policy implications for regulators.     

紧缩流动性会终止A股牛市吗?

"流动性过剩(主动信贷创造)推升股价"仅仅是个神话,是储蓄分流资金推动了本轮牛市。就此而论,市场短期内不必担心流动性枯竭的风险,但必须警惕这类资金使市场变得脆弱。     

Impact of liquidity on stock returns: an empirical investigation of the Tunisian stock market

This paper investigates the return–liquidity relationship on one Middle East and North Africa frontier market, the Tunisian Stock Exchange (TSE). The findings provide evidence that there is a significant and positive premium for companies with high price impact and low trading frequency. However, Tunisian investors appreciate more low spread stocks. We show, also, a non-linear relation between potential delays of execution and stock returns. In addition, we find that Tunisian investors require a premium to compensate past cumulative illiquidity risk (high price impact, low turnover and high potential delay of execution) over the prior three to 12 months and to compensate past cumulative spread over 12 months. We point out also that these effects are seasonal.     

Bank liquidity,stock market participation,and economic growth

We develop a growth model with banks and markets to reconcile the observed decreasing trend in the relative liquidity of many financial systems around the world with the increasing household participation in direct market trades. At low levels of economic development, the presence of fixed entry costs prevents the agents from accessing the market, and pushes them towards the banks, which provide high relative liquidity. We characterize the threshold after which the agents are rich enough to access the market, where the relative liquidity is lower, and show that the relative liquidity of the whole financial system (banks and markets) drops because of the increasing market participation. We provide some evidence consistent with this theoretical prediction: a one-unit increase in an index of securities market liberalization leads to a drop in the relative liquidity of between 17 and 27 per cent.     

The impact of short-selling and margin-buying on liquidity: Evidence from the Chinese stock market

We propose a framework based on limit order book to analyze the impact of short-selling and margin-buying on liquidity. We show that when short-sellers are perceived as informed, adverse selection may lead to uninformed traders withdrawing their limit orders. Given that the Chinese stock market has strong information asymmetry and a high proportion of uninformed traders, we predict that the pilot program launched in March 2010, which lifts restrictions on short-selling and margin-buying for a designated list of stocks, may have a negative impact on liquidity. We perform difference-in-differences tests and show evidence that allowing for short-selling and margin-buying indeed has a significantly negative impact on liquidity for stocks on the designated list. In particular, the negative impact on liquidity is more pronounced for stocks with high information asymmetry. Nevertheless, when short-selling volume dries up due to regulation changes in August 2015, i.e., the “T+1” trading rule on short-selling, we show that consistent with model predictions, lifting restrictions on short-selling and margin-buying has a positive effect on liquidity.     

Foreign institutional ownership and stock market liquidity: Evidence from Indonesia

From January 2002 to August 2007, foreign institutions held almost 70% of the free-float value of the Indonesian equity market, or 41% of the total market capitalization. Over the same period, liquidity on the Jakarta Stock Exchange improved substantially with the average bid–ask spread more than halved and the average depth more than doubled. In this study we examine the Granger causality between foreign institutional ownership and liquidity, while controlling for persistence in foreign ownership and liquidity measures. We find that foreign holdings have a negative impact on future liquidity: a 10% increase in foreign institutional ownership in the current month is associated with approximately 2% increase in the bid–ask spread, 3% decrease in depth, and 4% rise in price sensitivity in the next month, challenging the view that foreign institutions enhance liquidity in small emerging markets. Our findings are consistent with the negative liquidity impact of institutional investor ownership in developed markets.
