沪深300股指期货套利实证分析及市场特点研究

2010年4月上市交易的股指期货合约一直备受投资者关注。国内市场上也为保证其价格合理而推出融资融券等业务。根据无套利定价原理,股指期货与融资融券及沪深300指数现货之间存在一定价格关系。然而,其价格走势在中国是否合理,价格中是否存在大量套利机会呢?本文通过对股指期货首次交易及最近交易合约的套利机会实证分析,研究中国股指期货市场发展特点与其中存在的投资机会。     

对我国股指期货进行期现套利的思考

股指期货是以股票指数为标的资产的标准化期货合约.通过历史得知,在股指期货推出初期,有着大量套利机会.结合我国实际情况,通过持有成本定价模型,能够寻找处在不完美市场情况下对沪深300指数期货进行期现套利的可能,并对现货的构建以及指数的模拟做出了分析.     

沪深300股指期货套利及其实证研究

自沪深300股指期货推出以来,我国金融市场的交易品种变得更加丰富。同时基于沪深300股指期货的真实交易数据,我们可以获取并利用该数据进行实证分析,设计一系列的统计套利模型,发现当前市场所存在的套利机会。就目前我国的金融市场现状而言,市场有效性还有所欠缺,所以仍旧存在着较多的套利机会。本文利用真实交易数据对沪深300股指期货进行期现套利实证研究,以进一步完善股指期货市场的价格发现功能。     

中国股指期货定价模型探讨

我国沪深300股指期货的正式上市交易为投资者提供了新的机遇和挑战.股指期货交易者时刻面对的基本问题就是如何确定股指期货的价格.本文从股指期货的持有成本模型出发,分析若干经典定价模型的条件和局限,给出一个符合我国期货市场特点的股指期货定价区间模型,使得交易者能够简单直观地判断股指期货的套利机会和价格变动趋势,同时该模型能够为监管部门调控市场、稳定市场提供理论依据.     

我国股指期货定价及套利交易策略研究

首先对股指期货定价的理论基础、主要模型和方法、套利交易进行了概述,在此基础上对我国沪深300仿真交易数据进行实证分析,最后对我国股指期货套利交易提出了一些交易策略。     

股指期货期现套利模型及实证研究

该文根据持有成本模型构建股指期货期现套利模型，以沪深300股指期货真实交易数据为基础进行实证分析，得到不同市场行情下套利机会存在差别，并且主要以正向套利为主的结论。     

沪深300股指期货期现套利的可行性研究——基于统计套利模型的实证

从期现套利的基本思路出发,论证利用股指期货进行期现套利的可行性。实证表明,采用沪深300股指期货仿真交易的数据,并选择沪深300指数中权重排名前10的一篮子股票组合作为现货组合,运用基于误差修正模型(ECM)的统计套利技术,可以实现股指期货的无风险套利。     

沪深300股指期货与现货套利的实证分析

股指期货与现货的关系一直是一个研究热点。但是这些研究主要基于国外股指期货或沪深300股指期货仿真交易,而对正式推出后的沪深300股指期货的研究很匮乏。文章利用无套利区间分析了沪深300股指期货与现货之间的价格关系。结论显示,沪深300股指期货与现货之间有着很强的相关性,但是否存在相互决定关系还需要进一步研究。     

金融周期波动下股指期货对现货市场价格波动的影响

期货合约引入对现货市场波动性的影响一直备受争议,且现阶段金融周期与宏观经济的联系也备受关注。故本文以沪深300股票指数及对应的期货合约为研究对象,通过构建EGARCH模型,探究股指期货的引入能否有效抑制现货市场价格波动,以及在金融周期波动下,股指期货对现货市场的影响,并从期货市场参与者的角度解释股指期货对于现货市场的作用机理。最终得出结论:沪深300股指期货合约可以有效抑制现货市场的价格波动,而在金融周期的剧烈波动下,股指期货的引入会反向加大现货市场的价格波动;股指期货市场的套期保值交易可以有效抑制现货市场价格波动,而投机交易则增大现货市场的不稳定性,并且在金融周期波动较低时,期货市场交易对现货市场价格波动性的影响更为显著。     

股指期货价格与现货价格关系的分析

1.采取无套利分析原理推导股指期货的定价模型推导之前的假设条件:(1)忽略现货市场和期货市场的交易成本;(2)套利者可以构造出和股指期货构成完全一致的投资组合。设股指期货合约的交割时刻为T,FT是时刻T该期货合约的是市场价格,ST是时刻T该期货合约对应的基础资产的市场价格。     

中国概念股指期货跨市场套利研究——基于沪深300指数、H股指数、新华富时A50指数期货的实证分析

针对沪深300指数、H股指数、新华富时A50指数期货,给出确定投资比例、选择投资时机及度量投资风险的方法,对中国概念股指期货的跨市场套利机会进行研究,结论显示:中国沪深300股票指数与周边市场的中国概念股票指数之间存在着普遍关联性,并且这种关联性可以转化为套利机会。实证结果表明:当1:0.836546作为A50股指期货与H股股指期货的持仓比时,可以得到最优套利结果。     

股指期货动态套期保值率研究——基于DCC-MVGARCH模型

本文利用传统的回归模型(OLS)、双变量向量自回归模型(VAR)、双变量向量误差修正模型(VECM)和动态条件自相关双变量GARCH模型(DCC-MVGARCH)对恒生指数期货、标准普尔500指数期货、日经225指数期货、我国的沪深300指数期货的最优套期保值比率进行了估计,并采用基于风险最小化的方法对4种模型的套期保值有效性进行了比较。结果双变量向量误差修正模型估计出的最优套期保值比率更大,对4种模型的套期保值有效性的检验表明,采用动态条件自相关双变量GARCH模型(DCC-MVGARCH)估计得到的最优套期保值比率进行套期保值的效果,并非优于采用传统回归模型、双变量向量自回归模型、双变量向量误差修正模型估计得到的套期保值比率进行套期保值的效果。     

A revisit to the hedge and safe haven properties of gold: New evidence from China

We examine the role of gold as a hedge and safe haven from the perspective of Chinese investors. Using the Shanghai Futures Exchange (SHFE)-Gold futures prices and the CSI 300 index from 2008 to 2017, we find that gold is not a hedge against the Chinese stock market on average. However, gold acts as a safe haven when market returns are below their 1%, 5%, and 10% quantiles and during the two crash periods. Our findings apply to most of the industry sectors as well. We also show that the role of gold can change drastically due to some market policy reforms.

The impact of trading restrictions and margin requirements on stock index futures

Stock index futures in Chinese market have consistently diverged from their theoretical values. In this paper, we try to provide some explanations by proposing an equilibrium model. Although the model itself does not provide analytical solutions, it enables us to conduct extensive numerical studies and compare them with our empirical results on two major Chinese market indices, CSI300 and SSE50. Our results show that the divergence of stock index futures prices from their theoretical values may be due to various trading and regulatory constraints, such as position limits and margin requirements, which play significant roles in Chinese market.     

Impact of changes in the CSI 300 Index constituents

We investigate the price and trading volume effects of CSI 300 Index reconstitutions. In contrast to the Standard & Poor's (S&P) 500 Index, whose reconstitutions are carried out irregularly, as required, CSI 300 Index reconstitutions are scheduled semi-annually and performed based on predetermined rules. We find that, on average, prices increase (decrease) significantly for CSI 300 Index additions (deletions) followed by significant post-event price reversals; however, these price changes are less in magnitude than evidenced in extant research for the S&P 500 Index. The trading volume increases significantly for both CSI 300 Index additions and deletions in the short run. The trading volume subsequently reverts to normal levels for index additions but remains higher for index deletions. The findings are consistent with the price pressure hypothesis.     

Transaction Costs and Market Quality: Open Outcry Versus Electronic Trading

On May 10, 1999, the London International Financial Futures and Options Exchange (LIFFE) transferred trading in the Financial Times Stock Exchange (FTSE) 100 Index futures contracts from outcry to LIFFE CONNECT, its electronic trading system. We find lower spreads in the electronic market after the transition. However, the open outcry mechanism has higher market quality (or smaller variance of the pricing error) on the basis of Hasbrouck's (1993) model. Furthermore, employing the Hasbrouck (1991) model, we show that trades in the open outcry market have higher information content. Inventory control considerations also affect the electronic market more than the open outcry market. The overall results suggest that electronic trading should complement, but not replace, open outcry in futures markets. © 2001 John Wiley & Sons, Inc. Jrl Fut Mark 21: 713–735, 2001     

Hedging under the influence of transaction costs: An empirical investigation on FTSE 100 index options

The Black–Scholes (BS; F. Black & M. Scholes, 1973) option pricing model, and modern parametric option pricing models in general, assume that a single unique price for the underlying instrument exists, and that it is the mid‐ (the average of the ask and the bid) price. In this article the authors consider the Financial Times and London Stock Exchange (FTSE) 100 Index Options for the time period 1992–1997. They estimate the ask and bid prices for the index, and show that, when substituted for the mid‐price in the BS formula, they provide superior option price predictors, for call and put options, respectively. This result is reinforced further when they .t a non‐parametric neural network model to market prices of liquid options. The empirical .ndings in this article suggest that the ask and bid prices of the underlying asset provide a superior fit to the mid/closing price because they include market maker's, compensation for providing liquidity in the market for constituent stocks of the FTSE 100 index. © 2007 Wiley Periodicals, Inc.

Is the Australian wool futures market efficient as a predictor of spot prices?

Giles and Goss (1980) have suggested that, if a futures market provides a forward pricing function, then it is an efficient market. In this article a simple test for whether the Australian Wool Futures market is efficient is proposed. The test is based on applying cointegration techniques to test the Law of One Price over a three, six, nine, and twelve month spread of futures prices. We found that the futures market is efficient for up to a six-month spread, but no further into the future. Because futures market prices can be used to predict spot prices up to six months in advance, woolgrowers can use the futures price to assess when they market their clip, but not for longer-term production planning decisions. © 1999 John Wiley & Sons, Inc.
