股指期货对股票价格指数波动性影响——对日经225指数的实证分析

中国正在酝酿推出股指期货,而对股指期货的推出会对股票现货市场波动性产生影响至今没有定论.因此选择与我国样A股本标准差最接近的日经225指数为分析样本,采用加入虚拟变量的GARCH模型进行实证研究,通过对比日本证券市场在推出日经225股指期货前后,股市整体的波动性是否有明显改变进行实证分析,得出股指期货的推出有效地降低了日本股市波动性的结论,从而绐中国推出股指期货交易提供理论支持.     

股指期货推出对现货市场走势的影响

部分市场人士和投资者担心,股指期货的推出将会成为现货市场做空的动因,从而导致中国股市出现大幅震荡和下跌,即所谓的股指期货行情命题。笔者认为,只有结合一个国家或地区的经济社会发展阶段、经济金融背景,在充分估计非股指期货因素对特定现货市场的影响之后,才能够相对客观和准确地把握股指期货推出对现货市场走势产生的实际影响。

沪深300股指期货的推出对股票市场的影响

股指期货具有价格发现、套期保值等功能,是现货市场发展到一定阶段的产物。我国股权分置股改革已基本完成,股市机制不断健全,机构投资者日益壮大,股票市场健康快速发展。我国推出股指期货的条件已经成熟。本文在介绍股指期货基本功能和意义的基础上,深入分析了沪深300股指期货对我国股票现货市场的影响及稳步推出股指期货的保证措施。

股指期货对股票市场的波动性影响

2006年10月23日,中国金融期货交易所公布了《沪深300指数期货合约》、《交易细则》、《结算细则》和《风险控制管理办法(征求意见稿)》四个征求意见稿,表明我国股指期货推出进入倒计时。本文研究股指期货对现货市场产生的影响,通过研究分析我国周边国家或地区股指期货对现货市场的长期与短期波动性,并为预测分析我国股指期货推出后现货市场走势提供参考。本文从两个方面进行分析研究,一是通过选取中国台湾加权股价指数、日经225指数、马来西亚KLSE Composite、印度BSE30为标的物的股指期货推出前后两年现货股价指数走势为样本,分析其股指期货推出前后股价指数走势;二是利用印度BSE30指数的数据对印度股票市场进行实证研究,希望对我国股指期货市场建设有所借鉴。一、实证研究1.股指期货推出前后股价指数走势研究中金公司即将推出以沪深300指数为标的物的首个股指期货合约。因为股指期货在我国还属于新生事物,对其制定和操作没有相关的经验,加之我国证券市场有其自身特征,所以不能完全借鉴其他国家和地区的模式,但考察其他国家或地区股指期货设立之初其标的物指数波动情况,将有助于我国推出股指期货的市场预期。本文选择了中国台湾加权股价指数...     

股指期货利弊

推出股指期货的主要目的是给市场带来高效的定价机制,以消除过度投机,维护市场稳定。金融衍生产品能否被市场高效合理地定价,是市场是否健康的重要标志。股指期货做为20世纪80年代国际金融市场上最为重要的金融创新,目前已经是世界上交易量和流动性最好的金融衍生产品之一,被公认为是股市上最为有效的风险管理工具之一。推出股指期货对市场的     

股指期货对股票现货市场的影响

从整体上来看,股指期货市场和股票现货市场两市形成了"血肉相联"和"领先—滞后"的关系。从股指期货的推出到现在来看,它的影响是双面的,在我们手中如同一把"双刃剑",只有正确认识股市期货的积极以及消极作用,才能切实采取措施实现期货市场和股票现货的共同繁荣。     

股指期货与股票市场定价效率问题

股指期货的推出,大大提高了股票市场的定价效率.在无套利均衡市场上,股指期货价格由相关股票组合的价格及持有成本决定,股票现货价格成为影响股指期货价格的主要因素.但在动态非均衡市场上,股指期货的价格形成集中并传递大量信息,这些信息通过股指期货市场与股票市场间的套利机制及时传递到股票市场,增加相关股票组合价格的信息含量,引导和发现现货价格,从而提高股市的定价效率.     

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.

The case for management history

This article defines the case for treating management history as a discrete subject area, although one closely related to business, accounting, labour, and industrial history. It seeks to concentrate on the nature, process, and practice of management as an activity within the organization, and to argue that it is important that modern British managers understand the intellectual and cultural roots of their profession, since without these they will tend to be swayed by short-term management 'fads'. Within the broad topic there are several identifiable sub-areas for potential exploration, including the comparative historical development of management between different countries, management institutions, managerial careers and labour markets, management structures, management skills, and management thought and theory.     

The life and career of John Spence Ogilvy (1805-71), the first chartered accountant to emigrate to Australia

So far as the available evidence allows, this paper examines the life and career of John Spence Ogilvy, foundation member of the Society of Accountants in Edinburgh in 1854, who emigrated to Melbourne in 1856, but did not play a part in the development of an organized accounting profession in Australia.

The Impact of IFRS Adoption on an Agribusiness Company's Financial Statements

This fictional case is based on a Canadian public company that produces greenhouse vegetables. Focusing on the differences between International Financial Reporting Standards (IFRS) and Canadian Accounting Standards for Private Enterprises (ASPE), this case provides students an opportunity to (1) apply IFRS in a real world setting; (2) prepare and reconcile financial statements under ASPE and IFRS; (3) analyze the impact of IFRS adoption on key financial ratios; and (4) detect and explain differences in financial statements under ASPE and IFRS through common size analysis.
