中国股票市场流动性的比较研究   总被引:2,自引:0,他引:2  
本文根据股票买卖价差、有效价差、价格冲击指数、流动性指数、市场深度和大宗交易成本六个指标对中国股票市场流动性进行比较研究,研究表明:沪深两市的流动性均呈现出逐步改善的趋势.从流动性指数、市场深度及大宗交易成本上衡量,上海股市的流动性好于深圳股市,而从价格冲击指数及相对买卖价差衡量,深圳股市的流动性高于上海股市;与国际主要证券市场比较,沪深两市的流动性水平在新兴市场名列前茅,但低于全球平均水平.  相似文献

中国股票市场做空机制初探   总被引:5,自引:0,他引:5  
贺显南 《上海金融》2001,(10):30-31
股票市场的平稳运行取决于做多与做空机制的协调发展。中国股票市场日益积累的重要原因之一就是,与做多机制相对应的做空机制不完善并处于明显的劣势。引入信用交易、股指期货交易以强化做空机制,既是市场发展的需要,又具备了基本条件。  相似文献

产品市场势力、公司治理与股票市场流动性   总被引:2,自引:0,他引:2  
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。  相似文献

中国股市流动性风险测度研究   总被引:12,自引:0,他引:12  
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……  相似文献

股指期货是针对股票现货市场的需求应运而生的,是以股票价格指数为基础资产标的物的一种金融期货。自20世纪80年代首个股指期货合约在美国诞生以来,尽管只有短短20多年的发展历史,股指期货在世界范围的交易规模和市场影响力却得到了异常迅速的增长,并成为"20世纪最成功的期货品种之一"。2010年4月16日股指期货合约在我国正式上市交易,挂牌基准价定为3399点,这是我国资本市场的一个里程碑。  相似文献

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。  相似文献

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。  相似文献

Over the long term, the returns on smaller stocks are likely to be higher than the returns on larger stocks. This phenomenon has been called size effect, and a number of explanations have been proposed to account for it. Here we show that the difference in return between the larger and the smaller stocks can be accounted for by a liquidity premium for the smaller stocks, and we estimate the value of this premium using structural parameters for the capital distribution of the U.S. stock market during the 1990s The authors wish to express their gratitude to an anonymous referee for a very thorough and incisive reading, as well as for many constructive suggestions that have significantly improved this paper.

This article deals with the informativeness of iceberg orders, also known as hidden limit orders (HLOs). Namely, we analyze how the market reacts when the presence of hidden volume in the limit order book is revealed by the trading process. We use high-frequency book and transaction data from the Spanish Stock Exchange, including a large sample of executed HLOs. We show that just when hidden volume is detected, traders on the opposite side of the market become more aggressive, exploiting the opportunity to consume more than expected at the best quotes. However, neither illiquidity nor volatility increases in the short term. Furthermore, the detection of hidden volume has no relevant price impact. Overall, our results suggest that market participants do not attribute any relevant information content to the hidden side of liquidity.  相似文献

We show that US investors obtain substantial foreign exposure through their holdings of domestic equities. Domestic multinationals, in particular, provide significant foreign exposure. We also find that, although the average US investor is less tilted toward domestic multinationals, institutional investors do overweight domestic firms that are more internationally oriented. ‘Indirect’ foreign holdings through domestic multinationals are shown to be substantial; combining them with reported data on international positions almost doubles US investors’ total ‘foreign’ holdings. Our findings indicate that the home bias is not as severe as assessments based on reported international investment statistics suggest.  相似文献

全球商业银行流动性风险管理与监管的发展状况及其启示   总被引:11,自引:0,他引:11  
本文结合2007年夏秋爆发的美国次级债风波引发的全球流动性危机,从实践角度,对全球流动性风险的管理及其监管进行了一些探索和研究,着重分析了目前面临的挑战和显现的问题。同时结合国际良好做法,对加强我国流动性风险管理及其监管提出了相关建议,一是要切实高度重视商业银行流动性风险管理的监管;二是要及时制定流动性风险管理监管指引并加强对商业银行流动性的监控;三是要加强国际流动性风险管理和监管的跟踪研究;四是要加强各方协作,营造良好的流动性风险管理及监管环境。  相似文献

2007年以来,为缓解流动性过剩,控制货币信贷过快增长,央行频繁运用公开市场操作和上调存款准备金率等手段,加大货币回收力度.这虽然抑制了银行体系的流动性过剩,但对于作为弱势金融群体的农村信用社来说,紧缩货币政策实施所产生的累积效应对一些经济欠发达山区农信社的流动性管理带来了不利的影响,隐含的支付性风险不容忽视.  相似文献

Based on the concept that the presence of liquidity frictions can increase the daily traded volume, we develop an extended version of the mixture of distribution hypothesis model (MDH) along the lines of Tauchen and Pitts (1983) to measure the liquidity portion of volume. Our approach relies on a structural definition of liquidity frictions arising from the theoretical framework of Grossman and Miller (1988), which explains how liquidity shocks affect the way in which information is incorporated into daily trading characteristics. In addition, we propose an econometric setup exploiting the volatility–volume relationship to filter the liquidity portion of volume and infer the presence of liquidity frictions using daily data. Finally, based on FTSE 100 stocks, we show that the extended MDH model proposed here outperforms that of Andersen (1996) and that the liquidity frictions are priced in the cross-section of stock returns.  相似文献

This paper develops a model of banking fragility driven by aggregate liquidity shortages. Inefficiencies arise from a failure of the interbank market to smooth the available liquidity in such a shortage. We find that a standard lender of last resort policy is ineffective in restoring efficiency as it leads to offsetting changes in the banks’ supply of liquidity. In contrast, subsidizing the purchase of assets from troubled banks increases welfare by improving the banks’ liquidity holdings. The first best, however, is achieved by redistributing existing liquidity from healthy to troubled banks in a crisis.  相似文献

We examine the dynamics and the drivers of market liquidity during the financial crisis, using a unique volume-weighted spread measure. According to the literature we find that market liquidity is impaired when stock markets decline, implying a positive relation between market and liquidity risk. Moreover, this relationship is the stronger the deeper one digs into the order book. Even more interestingly, this paper sheds further light on so far puzzling features of market liquidity: liquidity commonality and flight-to-quality. We show that liquidity commonality varies over time, increases during market downturns, peaks at major crisis events and becomes weaker the deeper we look into the limit order book. Consistent with recent theoretical models that argue for a spiral effect between the financial sector’s funding liquidity and an asset’s market liquidity, we find that funding liquidity tightness induces an increase in liquidity commonality which then leads to market-wide liquidity dry-ups. Therefore our findings corroborate the view that market liquidity can be a driving force for financial contagion. Finally, we show that there is a positive relationship between credit risk and liquidity risk, i.e., there is a spread between liquidity costs of high and low credit quality stocks, and that in times of increased market uncertainty the impact of credit risk on liquidity risk intensifies. This corroborates the existence of a flight-to-quality or flight-to-liquidity phenomenon also on the stock markets.  相似文献

Hedging and liquidity   总被引:4,自引:0,他引:4  
This article develops a model for evaluating alternative hedgingstrategies for financially constrained firms. A key advantageof the model is the ability to capture the intertemporal effectsof hedging on the firm's financial situation. We characterizethe optimal hedge. A wide range of alternative hedging strategiescan be specified and the model allows us to determine in eachcase if the hedging strategy raises or lowers firms value andby how much. We show that hedging firm value, hedging cash flowfrom operations and hedging sales revenue are not optimal. Thearticle highlights the fact that every hedging strategy comespackaged with a borrowing strategy which requires careful consideration.  相似文献

在传统资产定价模型中依次引入换手率、成交金额、Amihud非流动性比率三种流动性度量指标,构造出改进后的Fama三因子模型,通过Fama-Macbeth两阶段回归的方法来探讨我国A股市场流动性溢价效应以及三种流动性度量指标的不同表现;然后,采用分位数回归的方法进一步检验三种流动性指标各自的适用范围。研究表明:中国A股市场存在较为显著的流动性风险溢价现象;不同的流动性指标与股票收益率之间的关系不同,换手率适合在低收益率情况下流动性的测度,Amihud非流动性比率更适合在中高收益率情况下流动性的测度,而成交金额指标未能通过检验,表现相对较差。  相似文献
