This paper examines the impact that the introduction of a closing call auction had on market quality at the London Stock Exchange. Using estimates from the partial adjustment with noise model of Amihud and Mendelson [Amihud, Y., Mendelson, H., 1987. Trading mechanisms and stock returns: An empirical investigation. Journal of Finance 42, 533–553] we show that opening and closing market quality improved for participating stocks. When we stratify our sample securities into five groups based on trading activity we find that the least active securities experience the greatest improvements to market quality. A control sample of stocks are not characterized by discernable changes to market quality. 相似文献

股指期货与现货市场的关系研究 总被引:1,自引:0,他引:1
本文从市场结构、交易执行效率和市场信息传播三个方面,由浅入深地展开了期现货市场关系的梳理和分析。股指期货市场的出现,一是使得原本现货市场单轨运行的市场结构变为了期现货市场双轨运行的新结构,增加了市场稳定性;二是依托期货交易方式的独特机制,大大提高了交易执行效率;三是期货价格也因此包含了更多内容,促进了市场信息的传播与扩散。同时,股指期货的独特设计使得其非常适合在危机条件下充分发挥功能,是一个重要的风险管理工具,已经成为现代资本市场的重要组成部分和基础性的内在稳定机制。 相似文献

We investigate the time series properties of the daily and weekly returns from the Athens Stock Exchange (ASE) index for the years 1987 to 1997. We investigate whether important time-series characteristics have changed significantly over time. The Greek market has recently undergone major changes including complete capital flow liberalization, the implementation of computerized trading, as well as significant increases in market volume and capitalization; we thus contrast the 1987–90 and 1991–97 periods. Our findings suggest the dynamics of the ASE composite index returns have changed as the market has developed. 相似文献

Stock issuance predicts future stock returns in the Korean market. This creates profitable trading opportunities. Abnormal returns exist in the zero-cost portfolio that short the firms issuing large numbers of shares and longs those issuing small numbers of shares. Their average abnormal return is 12 percent per annum, which is highly significant even after controlling for market, size, value, and momentum factors as well as transaction costs. The authors suggest the possibility of fixed costs in equity market timing. Only the sizable benefit from market timing over fixed costs motivates firms to increase net equity shares. 相似文献

坊间流传一个故事,说三十年前有一个罪犯被判死刑,行刑日寸子弹出了问题,第一枪是臭弹,犯人腿软跪下了;第二枪又没响,犯人裤子湿了;第三枪还是没响,犯人实在撑不住了,说别用枪了,用刀捅行不,太吓人了。三十年后的今年,股市第一波下跌到了4500点,投资者没减仓,坚持价值投资熬住了;第二波跌破3000点,投资者;中进去抢了反弹;但第三波股市又跌了个十连阴,有投资者终于崩溃了,说别跌了,把钱没收算了,太吓人了。这是一个笑话,但相信许多投资者会后悔年初没早些减仓,以减少损失,没有减仓或抄底抄到山腰上的投资管理人也成了市场嘲笑的对象。 相似文献

货币政策是否影响股票市场:基于中国股市的实证分析 总被引:8,自引:0,他引:8
货币政策是否影响股票市场,对该问题的回答涉及到中央银行是否有能力以及如何干预股票市场。本文运用协整检验、Granger因果关系检验、向量自回归模型等计量方法分析得出如下结论:1.货币供应量M1、M2与股市流通市值存在双向因果关系,名义利率Nr、实际利率Rr是股市流通市值Nc的Granger原因;2.中央银行可以通过货币供应量和利率两种方式影响股票市场,其中利率更有效。这些结论对于货币当局调控股票市场具有重要的借鉴意义。 相似文献

香港股市与内地股市的联动性研究 总被引:6,自引:0,他引:6
本文分3个阶段考察了香港回归以来,香港股市和内地股市之间的联动关系及其变化。协整分析表明,香港股市和内地股市之间存在长期的均衡关系,这种均衡关系在内地资本市场实行股权分置改革后更趋于稳定。Granger因果检验表明,香港回归以来香港股市和内地股市之间的引导关系在经历B股开放和股权分置改革后发生了变化。脉冲响应函数分析从动态的角度进一步验证了香港股市和内地股市之间的引导关系及其变化,并深入分析了单个变量的波动或冲击对其自身及另一变量的影响程度。 相似文献

Abstract: During 1999 and 2000 a large number of articles appeared in the financial press which argued that the concentration of the FTSE 100 had increased. Many of these reports suggested that stock market volatility in the UK had risen, because the concentration of its stock markets had increased. This study undertakes a comprehensive measurement of stock market concentration using the FTSE 100 index. We find that during 1999, 2000 and 2001 stock market concentration was noticeably higher than at any other time since the index was introduced. When we measure the volatility of the FTSE 100 index we do not find an association between concentration and its volatility. When we examine the variances and covariance's of the FTSE 100 constituents we find that security volatility appears to be positively related to concentration changes but concentration and the size of security covariances appear to be negatively related. We simulate the variance of four versions of the FTSE 100 index; in each version of the index the weighting structure reflects either an equally weighted index, or one with levels of low, intermediate or high concentration. We find that moving from low to high concentration has very little impact on the volatility of the index. To complete the study we estimate the minimum variance portfolio for the FTSE 100, we then compare concentration levels of this index to those formed on the basis of market weighting. We find that realised FTSE index weightings are higher than for the minimum variance index. 相似文献
