摘要:股票指数期货是上世纪八十年代金融创新过程中出现的最重要、最成功的金融衍生工具之一。它是以股市的价格指数为交易标的物的标准化期货合约。根据持有成本定价模型，股指期货理论价格应该是对现货价格、借贷利率等交易成本以及股息收益的综合反映。当期货价格偏离由各种因素综合作用形成的无套利区间时，投资者可以通过正向或反向期现套利获取一定的收益。
本文首先对股指期货套利交易予以概述，介绍了股指期货套利交易的概念、类型及特点。
在第二章中，本文着重介绍了股指期货的定价和期现套利的原理，并推导出证券市场的无套利区间。
在第三章中，针对我国正式推出沪深300股指期货交易后，我国投资者最可行套利交易策略，即期现套利予以详细的分析和实证研究，其中对于期现套利中采用ETF作为现货组合方式的操作模式进行了重点介绍，并实证分析了这种模式套利成败的关键因素：ETF跟踪偏离度。
在第四章中，结合我国金融市场实际情况以及根据过去一段时间的交易数据，对沪深300股指期货进行期现套利交易实例分析。
最后，本文得出以下结论：
(1)沪深300股指期货合约正式推出后，存在无套利区间，并且这个区间是可以大致计算出来的。
(2)对于期现套利的现货组合选择给出三种方案，研究表明其中尤以采用ETF组合的方案简便可行，并通过计算跟踪误差给出组合结构比例，其对于沪深300指数的跟踪误差在可接受范围之内。
(3)对于期现套利策略给出我国交易的模拟实例。
