摘　　要：沪深300已在国内上市1年多,现有的相关研究文献表明基于协整的跨期套利模型能够发现跨期套利机会并获得一定收益,然而固定样本期往往无法有效的反应最新数据的信息。为解决这个问题,建立了基于协整的跨期套利的EWMA模型,并运用沪深300股指期货合约的真实交易数据进行了实证研究。结果表明,该模型能够套利成功并获取可观的收益,因此该模型是有效的。The CSI 300 stock index futures have been listed in China for more than one year.Based on Cointegration theory associated with the arbitrage performance,the arbitrage of the stock index future was investigated.However,it exists a main problem in those studies,i.e.,the information in the latest data couldn＇t be revealed effectively if the sample period was fixed.To remedy this limitation,a new Cointegration theory-based EWMA model was proposed in the paper,and a empirical study was conducted by using the real traded data of the CSI 300 stock index futures to demonstrate the effectiveness and efficiency of the proposed model.
