股指期货期现套利的策略分析

近年来,关于股指期货的研究成果较多,但大多集中在股指期货推出对股票现货市场产生影响的领域,主要是从波动性、流动性及成分股溢价等角度进行深入的分析。事实上,股指期货是一种非常重要的套利工具,如何充分利用这一工具进行套利,无论在理论还是在实践领域,其研究的必要性和重要性都是不言而喻的。本文对如何利用股指期货进行期现套利进行了如下剖析。一、股指期货的期现套利方式高收益对应高风险,低收益对应低风险,每个理性投资者都想以尽可能低的风险来获取尽可能高的收益。在股指期货的各种投资策略当中,期现套利无疑是理性投资者最佳的投资选择。所谓期现套利指的是股指期货与股指现货之间的套利,是利用股指期货合约与其对应的现货指数之间的定价偏差进行的套利交易,属于无风险套利。即在买入(卖出)某个月份的股指期货合约的同时卖出(买入)相同价值的标的指数的现货股票组合,并在未来某个时间对两笔头寸同时进行平仓的一种套利交易方式。一般来说,期现套利方式可分为两种:正向套利和反向套利。正向套利即买入现货,卖出期货。若股指期货与股指现货的价格比高于无套利区间上限,套利者可以卖出股指期货,同时买入相同价值的指数现货,当期现价格比回落到无套利区间之后,对期货和...     

橡胶国内现货市场和期货市场套利模式分析

期货套期保值作为一种转移风险的方式,本质上即为套期保值者通过买卖期货产品将风险转移给其他交易者,从而达到规避风险和转移风险使套期保值者减少或者避免损失的目的,期现套利是套期保值的一种特殊方式。本文通过对期现套利做出简单介绍,详细阐述期现套利者在现货市场所面临的风险和套期保值者如何在现货和期货市场进行操作来规避和减少风险,从而为套期保值者进入期货市场规避转移风险提供理论依据。本文主要通过橡胶的期现套利进行介绍。

Index futures arbitrage before and after the introduction of sixteenths on the NYSE

We find that market efficiency increased and the arbitrage link between index futures and the stock market strengthened after June 24, 1997, when the New York Stock Exchange reduced the minimum change for stock prices and quotes from an eighth to a sixteenth of a dollar. There has been a substantial increase in the number of arbitrage trades reported to the Securities and Exchange Commission (SEC) since the reduction in the minimum price increment. The average number of stocks traded and the average dollar amount underlying each arbitrage trade increases and decreases, respectively. The average index futures mispricing error (MPE) that triggers arbitrage is lower and reverts to zero more quickly.     

Mean Reversion of Standard & Poor's 500 Index Basis Changes: Arbitrage-induced or Statistical Illusion?

Mean reversion in stock index basis changes has been presumed to be driven by the trading activity of stock index arbitragers. We propose here instead that the observed negative autocorrelation in basis changes is mainly a statistical illusion, arising because many stocks in the index portfolio trade infrequently. Even without formal arbitrage, reported basis changes would appear negatively autocorrelated as lagging stocks eventually trade and get updated. The implications of this study go beyond index arbitrage, however. Our analysis suggests that spurious elements may creep in whenever the price-change or return series of two securities or portfolios of securities are differenced.

Short Selling and Index Arbitrage Profitability: Evidence from the SGX MSCI and TAIFEX Taiwan Index Futures Markets

There are numerous impediments to market efficiency and index arbitrage in real capital markets, including the uptick rule on short selling, execution risk, market impact costs, regulatory barriers, and capital constraints. Adopting and relaxing the uptick restriction in the Taiwan stock market facilitated a study on whether adjustments in this restriction influence the efficiency and arbitrage of the Singapore Exchange Limited (SGX) and the Taiwan Futures Exchange (TAIFEX) index futures markets. This study examines the above issues using five-minute intraday transaction data and performs an ex post test of arbitrage, ex ante test of arbitrage, and regression analysis. Empirical results indicate that relaxing the uptick rule should improve market efficiency and facilitate long arbitrage, subsequently accelerating the adjustment to no-arbitrage bounds and helping to decrease ex post and ex ante mispricing and underpricing following the relaxation.     

Price Expectation and the Pricing of Stock Index Futures

Capital markets are not perfect or frictionless, and arbitrage mechanism cannot be complete, particularly for index arbitrage. This study constructs a theoretical foundation to explain why the price expectation of the underlying asset should be entered into the pricing formula of stock index futures. The price expectation and incompleteness of arbitrage then are taken into account to develop a pricing model of stock index futures in imperfect markets. This study also presents three approaches for estimating the model parameter. Finally, the concept of the degree of market imperfection is defined and the valuation model is provided.     

Measuring Pricing Inefficiencies Under Stressful Market Conditions

This study examines the mispricing and time between arbitrage trades of the Hong Kong Hang Seng index futures and index options contracts under various stressed market conditions. Ex‐ante trading profits and differences in time between trades across up and down as well as stressed and non‐stressed markets are used to measure how well the derivative markets perform under emotional distress. We find evidence of illiquidity in stressed and down markets. In stressful markets and down markets, liquidity suppliers are less likely to trade against the informed traders. This, in turn, leads to longer time between trades and higher arbitrage profits.     

Trade Imbalances and Inventory Effects in Long-term S&P 500 Index Options

This article investigates how trade imbalances affect prices in the S&P 500 Long‐term Equity Anticipation Securities (LEAPS) market. From 1994 to 1996, put volume was 30 times higher than call volume, and public purchases of puts vastly outnumbered sales. We find that LEAPS put quotes are revised following trade imbalances by more than can be explained by information effects, suggesting that put prices are subject to price pressure or inventory effects. The results suggest market frictions are important in the pricing of options, at least in settings in which arbitrage is particularly costly and public demand leans toward one type of order.     

Options Arbitrage in Imperfect Markets

Option valuation models are based on an arbitrage strategy—hedging the option against the underlying asset and rebalancing continuously until expiration—that is only possible in a frictionless market. This paper simulates the impact of market imperfections and other problems with the “standard” arbitrage trade, including uncertain volatility, transactions costs, indivisibilities, and rebalancing only at discrete intervals. We find that, in an actual market such as that for stock index options, the standard arbitrage is exposed to such large risk and transactions costs that it can only establish very wide bounds on equilibrium options prices. This has important implications for price determination in options markets, as well as for testing of valuation models.     

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。
