对国外股指期货市场发展的思考

本文从股指期货的定义和发展过程入手,依次对美国、日本、新加坡股指期货市场的发展历程进行了介绍.通过比较,分析它们在各自发展过程中取得的成就,总结其经验教训,并结合中国国情,提出中国在发展股指期货市场中应注意的问题.     

中外股指期货市场监管架构比较研究

发达国家的历史经验证明,股指期货市场的发展和监管必须相辅相成,才能有利于整个经济的稳定和发展。美国、英国、德国、日本以及香港地区股指期货市场监管架构不尽相同,对我国股指期货市场监管也各有借鉴。我国应借鉴发达国家和地区股指期货市场监管的经验,加强对沪深300指数期货交易的监管,建立健全对股指期货市场的监管体系。

股指期货市场发展问题研究

本文在考察国外股指期货市场产生和发展历史的基础上,介绍了香港和国内股指期货市场的发展情况,并对国内期货市场在亚太地区的地位进行了比较研究。     

股指期货与股票现货市场竞争关系研究——来自中国的经验证据

本文利用模拟生态学中种群间动态关系的Lotka-Volterra模型,对沪深300股指期货同股票现货市场在交易规模方面的竞争关系进行实证分析。研究结果表明,沪深300股指期货推出初期,股指期货市场与股票现货市场在交易规模方面存在竞争性的交易转移效应;随着股指期货市场相关规则的不断健全和完善,股指期货市场与股票现货市场在交易规模方面由竞争关系转变为共存关系,出现交易引资效应。同时,研究还发现,股指期货市场与股票现货市场之间关系由竞争性转变为共存性的重要原因是股指期货市场监管力度的加大,股指期货市场投资者结构的优化,以及股指期货市场期现套利交易的盛行。     

股指期货市场操纵与价格发现功能的关系研究

股指期货市场操纵会影响股指期货市场的价格发现功能,同样地,股指期货市场的价格发现功能也会影响股指期货市场的操纵行为。本文在理论探讨的基础上,利用股指期货主力合约及对应的沪深300指数高频数据对市场操纵行为进行实证分析。研究结果表明,当操纵嫌疑只存在于期货市场时,股指期货市场的价格发现功能将会减弱;当操纵嫌疑存在于期货、现货两个市场时,股指期货市场的价格发现功能相对会增强。而且,当股指期货市场价格发现功能较强时,市场操纵的难度和成本都将下降。当前中国股指期货市场的操纵行为可能主要局限于某些个别的、离散的交易日内,系统地通过操纵现货指数来操纵期货市场的可能性较低。     

关于股指期货市场风险管理与策略的研究

股指期货是20世纪80年代发展起来的新型金融衍生工具,且已经发展成为金融市场中不可或缺的重要组成部分,股指期货市场在很大程度上促使投资策略更加具有多样化,在增强我国金融市场竞争力方面也起到了至关重要的作用。本文以此为背景,针对股指期货市场风险管理与策略进行了研究,旨在为我国股票指数期货市场的风险管理提供可参考的建议。     

股指期权对股指期货的促进作用:来自韩国的证据

本文结合解析韩国KOSPI200期权对于KOSPI200期货市场的影响,论证股指期权市场对股指期货市场在提高流动性和培育机构投资者方面的显著作用。借鉴韩国股指衍生品市场发展经验,笔者认为在沪深300股指期货平稳运行之后,要选择时机及时推出股指期权,这样可以保证良好的流动性。为此,应当加快制定股指衍生品市场体系的发展战略。     

中国股指期货市场的特有风险及应对策略

作为一个新兴市场国家,我国股指期货市场在运作过程当中面临着交易主体结构风险、股指期货品种风险以及政策干预风险等特有风险。目前我国的股指期货风险管理体系并不足以完全覆盖和管理这些特有风险,为了解决这一问题,需从宏观和微观两个维度采取应对策略,应健全宏观层面的风险管理措施以防范股指期货市场的系统性风险。加强微观层面的风险控制措施以提升微观审慎监管力度,共同构建中国股指期货市场的长效稳定机制。     

中国股指期货“助涨助跌效应”实证研究

利用E-G两部法协整检验、向量误差修正模型、VAR模型、Granger因果性检验及脉冲响应和方差分解全面剖析了股指期货与现货市场之间的联动性。实证研究结果表明股指期货和股票指数之间存在长期的均衡关系,股票指数短期的过度偏离会导致长期非均衡误差的弱势修正,当市场受到确定性信息冲击时,股票期货市场对股票现货市场具有助涨助跌作用;当市场受到不确定信息冲击时,股票现货市场对股票期货市场具有助涨助跌作用。     

Do Newly Listed Derivatives Affect the Market Risk Premium in a Thin Stock Market?

This study examines the effects on the stock market unitary risk premium and volatility associated with the listing of stock and stock index derivatives in Switzerland. Based on a univariate GARCH (1,1) specification of the stock index variance and a time-varying unitary risk premium representation, we can reject the hypothesis that stock and stock index derivatives listings do not affect the total risk premium. Contrarily to previous empirical evidence, we find that derivatives listings affect both the conditional market returns' variance and the unitary risk premium through structural shocks. The gradual market completion hypothesis is further corroborated in that, cumulatively, the three stock and stock index options futures derivatives listings reduced the unitary risk premium while the marginal impact of each successive listing decayed.

限制交易政策如何影响期现关系?——对股指期货价格发现功能的实证检验

本文利用2015年中国股市大幅下跌期间,对股指期货严格限制交易政策这一独特事件前后的高频数据,研究限制交易政策对股指期货与股票市场价格引导关系的影响。利用I-S模型和分位数回归方法的实证结果表明:限制交易政策实施前,股指期货对股票市场的价格影响更强,尤其表现在价格急剧下跌时期;限制交易政策显著增加了期货市场交易成本,从而降低了期货市场的信息份额,削弱了其对股票市场的价格影响,并且改变了期货价格对现货价格“助跌强于助涨”的影响模式,增强了股指期货在价格上涨时对股票市场的影响。研究结果一方面直接量化了期货交易成本变动对其价格发现功能的负面影响,另一方面也从价格引导关系的视角提供了股市危机时期股指期货限制交易政策监管效果的实证证据。     

沪深300股指期货定价误差及影响因素分析

文章运用持有成本模型、无套利定价原理以及回归分析,分别对日交易数据、日内5分钟数据对我国沪深300股指期货的定价误差及影响定价误差幅度的因素进行了实证研究,研究表明我国沪深300股指期货的价格在大多数时间是偏高的,在考虑套利成本的情况下,股指期货的定价在大多数时间是有效率的,但是在股票市场大幅波动的时段,股指期货的定价在存在较大幅度的定价误差。从影响股指期货定价误差幅度的因素来看,距到期日越远定价误差越大,现货指数波动越剧烈定价误差越大,股指期货持仓量对定价误差没有显著影响,加息对定价误差的影响跟加息日期有关。     

沪深300股指期货VaR-GARCH模型风险管理研究——基于恒指期货的比较视角

股指期货是以股票指数作为标的的金融衍生产品,其在金融风险管理中具有重要作用,同时自身也面临较大的风险。VaR—GARCH模型能够较好地模拟金融市场时间序列数据,并作出相应的估计值,是当前主流的风险管理方法。本文基于香港恒指期货的比较视角,对我国去年推出的沪深300股指期货交易进行VaR—GARCH模型实证分析,得出VaR—GARCH模型能够较好地管理沪深300股指期货的风险的结论,并建议加强VaR技术的运用和加强跨市监管,更好地管理股指期货的风险。     

Volatility spillover and investment strategies among sustainability-related financial indexes: Evidence from the DCC-GARCH-based dynamic connectedness and DCC-GARCH t-copula approach

This study analyzes the dynamic connectedness between the ESG stock index, the renewable energy stock index, the green bond stock index, the sustainability stock index, and the carbon emission futures by employing a novel method: the DCC-GARCH-based dynamic connectedness approach. Given the strong volatility spillover among these indexes, we adopt the DCC-GARCH t-copula model to calculate these indexes' hedging ratios and portfolio weights. Our findings show that the carbon emission futures are the volatility transmitter, and the green bond is the volatility receiver. The total dynamic connectedness is affected by international political, economic, and other events. Furthermore, for stock market volatility investors, taking the long position in carbon emission futures and the short position in renewable energy stock can achieve the highest hedging effect.     

A dynamic equilibrium model for U-shaped pricing kernels

This paper proposes a dynamic equilibrium model that can provide a unified explanation for the stylized facts observed in stock index markets such as the fat tails of the risk-neutral return distribution relative to the physical distribution, negative expected returns on deep OTM call options and negative realized variance risk premiums. In particular, we focus on the U-shaped pricing kernel against the stock index return, which is closely related to the negative call returns. We assume that the stock index return follows a time-changed Lévy process and that a representative investor has power utility over the aggregate consumption that forms a linear regression of the stock index return and its stochastic activity rate. This model offers a macroeconomic interpretation of the stylized facts from the perspective of the sensitivity of the activity rate and stock index return on aggregate consumption as well as the investor’s risk aversion.     

Price Discovery in Chinese Stock Index Futures Market: New Evidence Based on Intraday Data

Using high-frequency data, this study investigates price discovery in the newly established stock index (CSI300) futures market in China. Our empirical results reveal new evidence that the CSI300 index futures market play a dominant role in the price discovery process about one year after its inception and new information is disseminated more rapidly in the stock index futures market than the stock market. This is different from findings in the previous literature. Our results also imply that the index futures market has evolved and can be used as a price discovery vehicle. Thus the CSI300 stock index futures market plays an important role in the capital markets in China.     

我国股市扩容与大盘走势实证分析

融资功能是证券市场的主要功能之一,但股市扩容往往被列为“利空”因素,实证研究表明扩容本身并不会直接导致股指下降,而且能从多个方面对股市稳定健康发展发挥积极作用,我国A股市场指数正是在不断扩容的基础上迭创新高总体保持上升趋势,并且大扩容往往是在大牛市的背景中完成的。
