最佳套期保值比率(OHR)的估计方法是金融工程理论研究的核心问题之一。从20世纪初所谓的“幼稚”方法到1970年代趋于成熟的JSE方法,以及后来的HKM方法和Adler—Dumas方法等,每一类新方法从某种程度上说都更好地起到了保值效果。然而,它们共同的症结都在于所估计的OHR是不随时间而变化的。自1982年Engle提出ARCH模型以来,不少国外学者已经开始尝试将ARCH/GARCH模型应用到OHR的研究中,从而求得动态的(或时变的)OHR,以期待衍生工具的套期保值效率得到进一步的提高。  相似文献

将对股指期货套期保值策略进行比较全面的理论和实证研究。首先,概述了股指期货套期保值的相关理论,综述了套期保值的关键环节是最优套期保值比率的确定的相关的模型;其次,运用协整等分析方法,采用最小二乘回归模型(OLS)、向量自回归模型(VAR)、误差修正模型(ECM)、广义自回归条件异方差模型(GARCH),分别对中国沪深300股指期货最优套期保值比率进行了实证研究,并对各模型的套期保值绩效做出了评价,得出ECM模型是最优的,是最适合中国沪深300股指期货的套期保值率估计模型。  相似文献

中国大豆期货市场最优套期保值比率的实证研究   总被引:1,自引:0,他引:1  
在总结评述国际上成熟的最优套期保值比率估计方法的基础上,采用OLS、VAR、B-ECM、B-GARCH、ECM-B-GARCH五种模型和Lien提出的套期保值绩效衡量指标,对我国大豆期货市场的套期保值比率和套期保值绩效进行了实证研究。结果表明:对于中国大豆期货市场而言,按照OLS模型估计的最优套期保值比率进行动态套期保值能够最大程度地降低风险;基于VAR模型与B-ECM模型的结果次之;按照B-GARCH模型和ECM-B-GARCH模型估计的最优套期保值比率进行动态套期保值,风险降低程度最小。  相似文献

文章针对企业套期保值过程中由于套保比率的设定以及入市点的错误选择使得企业面临亏损风险的问题而提出对策。笔者在套期保值比率问题上首次引入了寻找合理判断入市点的模型并给出了具体方法。利用金融工程中无套利的复制原理,复制出了一个远期的权益,从而得出了文章所认为的最优套保比率,为实务界经常运用的选择入市点问题给予理论支持。文章构建的模型得出,在套保比率的设定问题上不但要选择入市点,还要选择套保的时间因素。在买期保值上,当判断出市场行情有利时我们选择相对较大的保值比率,这样可以使我们能尽量获取基差上扬所带来的收益,另外又不至于把套保比率无限扩大使得套保变成投机,以防在万一出现行情错误的时候出现大幅亏损。在卖期保值上,当判断行情有利时,选择相对较低的保值比率,这样可以使我们能尽量获取基差下跌所带来的收益,另外又不至于把套保比率无限缩小甚至不保使得套保变成投机,以防在万一出现行情错误的时候亏损。  相似文献

随机的碳排放价格变化直接导致资产组合的投资风险加剧,影响碳排放现货与期货资产的投资组合策略。依靠商品期货价格的期限结构,本文提出了一种新的在便利收益下动态套期保值比率及其套期保值效果评价方法。动态套期保值比率是由现货和便利收益的波动率、协方差及其相关系数、距离到期日时间、便利收益均值回复速度等参数存在紧密关联性。为了有效地规避碳排放现货价格剧烈波动所引发的市场风险,市场参与者利用便利收益的历史信息优化调整期货与现货的对冲比例,确定最优化的套期保值比率,可以有效规避现货资产的市场风险,实现资产投资组合最佳的投资收益。  相似文献

This article aims at exploring the performance of the price discovery function of cornstarch futures market in China. In order to test the stationarity of the cash and futures prices of cornstarch, the augmented Dickey–Fuller test is applied. Both prices are integrated of order one. Then, the Johansen cointegration test is conducted to test the cointegrating relationship between those two prices. Finally, the Granger causality test is performed to observe the direction of causality. The evidence shows that there is a long-run relationship between cash and futures prices and the futures price Granger causes cash price. As a whole, price discovery of cornstarch market in China is present although it is a newly emerged market.  相似文献

我国期货市场亟需期货投资基金   总被引:2,自引:0,他引:2  
我国期货行业自进入21世纪以来取得了飞速发展,无论品种规模还是成交量都已位居世界前列,然而,在国外已经成为期货市场主力的期货投资基金在我国却难觅其踪。期货投资基金可以优化和改善投资组合,规避股市系统性风险,实现专家理财保护中小投资者利益。实际上,从市场规模、运作现状、风险控制、资金充裕度以及证券投资基金在我国发展的成功经验来看,我国已基本具备设立期货投资基金的基础。但期货投资基金毕竟是一个高风险的投资工具,国内对它的研究还比较薄弱,法律体系和监管机制仍待完善,产品的种类和活跃程度仍待加强,在基金公司的设立方式上仍需谨慎选择,对于期货投资基金亟需的高端综合型人才的培养都是我国急需解决的问题。  相似文献

Price discovery is the basic function of futures market, and whether the futures market has the function of price discovery is an important research field for scholars both at home and abroad. This paper classifies the test methods and models on a basis of previous research, and introduces the applicable premise of research methods and models as well as the major research achievements of scholars at home and abroad, and also reviews the shortcomings of test methods and models.  相似文献

This paper examines whether the equity market uncertainty (EMU) index contains incremental information for forecasting the realized volatility of crude oil futures. We use 5-min high-frequency transaction data for WTI crude oil futures and develop six heterogeneous autoregressive (HAR) models based on classical HAR-type models. The empirical results suggest that EMU contains more incremental information than the economic policy uncertainty (EPU) for forecasting the realized volatility of crude oil futures. More importantly, we argue that EMU is a non negligible additional predictive variable that can significantly improve the 1-day ahead predictive accuracy of all six HAR-type models, and improve the 1-week ahead forecasting performance of the HAR-RV, HAR-RV-J, HAR-RSV, HAR-RV-SJ models. These findings highlight a strong short-term and a weak mid-term predictive ability of EMU in the crude oil futures market.  相似文献

This investigation of the switch from open-outcry trading to electronic trading on the Hang Seng Index (HSI) futures contract reveals that the bid–ask spread narrows and the futures price plays more of a role in information transmission. Factors, such as anonymity in trading and fast order execution in electronic trading, attract informed traders to the futures market, enhancing the information flow. Our results provide support for the worldwide trend of transforming open-outcry markets into electronic trading platforms.  相似文献

This paper develops an extended version of the quality-adder model by allowing for heterogeneous markets. Based on this model, it presents an empirical analysis of innovation-based growth at the market level using a technometric measurement concept. It can be shown that a growth-promoting effect due to technological progress in a particular single year is observed after between 2 and up to 7 years. This is true not only for highly innovative markets but also for those in which fewer R&D resources are invested.  相似文献

A study was carried out to analyze futures markets for tradable rights after a cash market was initiated. Furthermore, some indication was given on the size of such a futures market to provide insight into its viability. Futures markets can play a role in solving environmental problems, by making the market for pollution rights (i.e. P2O5 rights) and agro rights (milk rights, sugar rights and P2O5 rights) more effective and transparent. Moreover, the market for tradable rights would be able to meet the users' need for hedging. This paper investigated the possibility of introducing a futures markets for tradable P2O5 rights and the commodity manure. Because there is already a cash market for manure, although not well developed yet, and there will be a cash market for P2O5 rights, a futures market is a logical sequel. The futures market can play a role in implementing agricultural policy efficiently and with respect to manure and P2O5 rights can be an economically efficient solution to environmental problems.We acknowledge the financial support of the ATA (Agricultural Futures Market Amsterdam).  相似文献

中国股票市场正在经历前所未有的变革,推出股指期货就是其中之一。推出股指期货可以完善证券市场的功能体系。有利于培育投资者的成熟度,进而促进股市与经济运行的关联程度,发挥股市经济“晴雨表”的功能。同时,中国已有17年股票市场和商品期货市场的管理经验,具备了发展股指期货的条件,只要能充分控制其潜在的风险,推出股指期货对整个股票市场是有利的。  相似文献

本文借助于信息共享模型与波动溢出效应模型对我国大豆和小麦的期、现货市场之间的价格发现进行了多层次的实证研究,定量描述了期、现货市场在价格发现中作用的大小,深入刻画了我国农产品期、现货市场之间的动态关系.研究结果显示:大豆期、现货价格之间存在双向引导关系,小麦仅存在期货对现货的单向引导关系;期、现货市场均扮演着重要的价格发现角色,且期货市场在价格发现中处于主导地位;期、现货市场之间均存在双向波动溢出关系,但现货市场来自期货市场的波动溢出效应均强于期货市场来自现货市场的波动溢出效应;并且,随着期货市场的发展,期、现货市场之间的波动溢出程度均呈逐渐增强态势.  相似文献
