浅议股指期货的会计处理问题

<正>1982年2月,美国堪萨斯期货交易所推出了世界上的首个股指期货合约。此后,世界各大交易所纷纷推出股指期货交易品种。随着我国资本市场的日渐发展,我国的股指期货也即将推出,由于股指期货的杠杆性、高风险性和复杂性特征,因此如何在实际的工作中对股指期货进行有效的会计核算并不断地完善和发展会计核算的程序和方法,成为报表相关者所关注的问题。     

期货套保的会计处理

对股指期货卖空套期保值功能的质疑

商品期货套期保值的原理和操作适用于股指期货的多数情形,但是并不完全.由于商品期货和股指期货投资主体盈利模式不同,卖空操作的前提和必要性不周,导致股指期货的卖空套期保值虽然操作上可行,但却缺乏足够的经济意义.

衍生金融工具交易保证金会计处理分析

1982年股指期货产生后，其交易已在世界主要资本市场得到迅猛发展，尤其是进入20世纪90年代以后，股指期货已成为全球金融市场中最具活力的组成部分。随着我国金融市场的逐步完善和配套措施的逐步具备，股指期货越来越受到各界关注，它的推出也不再遥远。股指期货保证金是股指期货交易顺利进行的重要手段，同时也是会计信息披露的一个重要     

基于VaR的股指期货套期保值研究

中国证券市场起步于90年代初期,由于缺乏风险对冲工具和做空机制,市场长期以来一直处于单边市状态,即投资者只能通过买入股票并等待其上涨来获得收益,如果市场处于下跌通道之中,投资者或者被动忍受损失,或者离场观望。而中国证券市场波动又比较剧烈,这就更加大了投资者的投资风险。沪深300股指期货的推出将使得国内证券市场格局发生重大变革：一方面,投资者可以通过投机来获利;另一方面,投资者可以通过股指期货进行避险,即所谓的套期保值。     

我国推出股指期货的可行性及亟待解决的问题

近年来，股指期货凭借着流动性高、交易成本低、市场效率高的独特魅力以及良好的价格发现，套期保值功能，成为了20世纪80年代最成功的金融创新品种，并在金融衍生品交易中占据了举足轻重的地位。随着我国资本市场的不断开放与发展，国内外投资者均对中国的股票市场产生了浓厚的兴趣，都想在新兴的市场中赢得超额的利润。但是我国是否已经具备了推出股指期货的条件，推出股指期货对我国期货市场发展究竞具有什么样的意义，对此进行了分析，以期为股指期货推出提供参考。     

股指期货最优套期保值比率估计方法研究

本文利用普通线性回归模型、VAR、ECM、FIECM四种模型来计算静态最优套期保值比率,以及利用VAR-GARCH、ECM-GARCH、FIECM-GARCH三种模型来计算动态最优套期保值比率,并利用事后样本数据来比较这些估计效果。研究结果表明,考虑异方差性的模型动态最优套期保值比率普遍小于未考虑到异方差性的静态最优套期保值比率;而动态最优套期保值比率的保值效果则明显优于静态最优套期保值比率的保值效果。     

Intraday volatility in the stock index and stock index futures markets

We examine the intraday relationship between returns and returnsvolatility in the stock index and stock index futures markets.Our results indicate a strong intermarket dependence in thevolatility of the case and futures returns. Price innovationsthat originate in either the stock or futures markets can predictthe future volatility in the other market. We show that thisrelationship persists even during periods in which the dependencein the returns themselves appears to weaken. The findings arerobust to controlling for potential market frictions such asasynchronous trading in the stock index. Our results have implicationsfor understanding the pattern of information flows between thetwo markets.     

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     

Price discovery and changes in regimes for stock index futures

In this paper, we propose a cointegration system that considers regime shifts in the stock index futures markets. Meanwhile, three such markets—the S&P, the CAC 40, and the Nikkei 225 index futures—are examined using the proposed model. The empirical evidence shows that the cointegration system with consideration of regime shifts performs better than the usual cointegration system without considering regime shifts. Moreover, the three futures markets exhibit different patterns for distinct regimes.     

Reexamining intraday simultaneity in stock index futures markets

This note examines three empirical examples involving intraday dynamic relationships associated with stock index futures markets. Researchers often employ a vector autoregressive ( ) model to analyze such high frequency transactions data. While such a model can provide useful information regarding the nature of causal priority inherent in the data, it is not the proper model to investigate the structural relationships of interest, because it omits the contemporaneous interaction. On the other hand, a model specification which is altered to incorporate simultaneity may enable the data to reveal the structural relationships of interest.     

A theory of trading in stock index futures

It is demonstrated that markets in stock index futures or, moregenerally, in baskets of securities, provide a preferred tradingmedium for uniformed liquidity traders who wish to trade portfolios,because adverse selection costs are typically lower in thesemarkets than in markets for individual securities. Thus, anexplanation is provided for the immense liquidity and popularityof markets in stock index futures. Implications are also developedfor the effect of the introduction of a basket on market liquidityand the informativeness and variability of component securityprices, and for the price relationship between the basket andits underlying portfolio.     

沪深300指数与股指期货价格变化关系的检验

在沪深300股指期货推出两年以后,为了验证期货市场的价格发现功能,本文利用VAR模型对沪深300股指期货和现货价格的每分钟收益率序列实际数据进行检验.实证检验结果显示期货价格变化对未来现货价格变化有显著影响,持续时间可达5分钟以上,而现货价格对期货价格变化没有显著影响.因此,沪深300指数期货市场已经发挥了较强的价格发现功能.同时,我们发现对股指期货和现货市场而言,VAR模型具有较强的稳定性,在利用历史数据预测未来指数价格变化中有较强的实用价值.     

Cross hedging single stock with American Depositary Receipt and stock index futures

This paper investigates the cross hedging effectiveness of individual stock in a market that does not have single stock futures traded using American Depositary Receipt (ADR) and stock index futures. We apply Caporin and Billio’s Multivariate regime switching GARCH to capture the state-dependent covariance structure of underlying stock, ADR and stock index futures. Empirical results indicate that in general simultaneous hedging with both ADR and index futures creates hedging gains and incorporating regime switching effects further increases the hedging performances.     

Margin exceedences for European stock index futures using extreme value theory

Futures exchanges require a margin requirement that ensures their competitiveness and protects against default risk. This paper applies extreme value theory in computing unconditional optimal margin levels for a selection of stock index futures traded on European exchanges. The theoretical framework focuses explicitly on tail returns, thereby properly accounting for large levels of risk in measuring prudent margin levels. The paper finds that common margin requirements are sufficient for each contract, with the exception of the Norwegian OBX index, in providing equitable costs for traders. In addition, the paper shows the underestimation bias in margin levels that are calculated assuming normality. Differing margin requirements reflect the unconditional and conditional trading environments.     

Hedging effectiveness of the Athens stock index futures contracts

This paper examines the hedging effectiveness of the FTSE/ATHEX-20 and FTSE/ATHEX Mid-40 stock index futures contracts in the relatively new and fairly unresearched futures market of Greece. Both in-sample and out-of-sample hedging performances using weekly and daily data are examined, considering both constant and time-varying hedge ratios. Results indicate that time-varying hedging strategies provide incremental risk-reduction benefits in-sample, but under-perform simple constant hedging strategies out-of-sample. Moreover, futures contracts serve effectively their risk management role and compare favourably with results in other international stock index futures markets. Estimation of investor utility functions and corresponding optimal utility maximising hedge ratios yields similar results, in terms of model selection. For the FTSE/ATHEX Mid-40 contracts we identify the existence of speculative components, which lead to utility-maximising hedge ratios, that are different to the minimum variance hedge ratio solutions.
