300 股指期货自 2010 416 日上市以来,得到了众多投资者的青睐
目前已经成为一个成熟的期货品种。我国机构投资者在股指期货投资上热衷于
风险的套利交易,特别是稳健性高的期现套利交易。但自 2011 年以来,沪深 300
股指期货市场已经较为成熟,期现套利机会并不多,这严重制约了套利资金的
利活动。因此,挖掘新的套利机会成为当前迫切的命题。
股指期货的跨期套利是套利投资的新方向。特别是随着交易模式系统化的
展,统计套利成为量化投资领域的主打对冲策略我国股指期货统计套利的研
究,不论是就市场有效性探讨还是对于股指期货的监督管理,抑或是投资者的
序化交易,都具有十分重要的意义。
本文采用 5分钟高频收盘价格数据,选取我国沪深 300 股指期货作为研究对
象。首先应用协整理论对当月和次月连续合约间的关系进行分析,协整检验表
当月合约和次月合约存在长期均衡关系,可以用来构建协整套利。同时,基于

为更深入分析价差,接着将价差分解为均值中枢和随机扰动项两部分,与
往研究不同,本文采用指数加权移动平均法来估计价差的均值中枢。通过敏感
Monte Carlo 相关,对样本内数立一般模型,
结果表明本文设计的统计套利策略在样本内获得了 16.71%的年化收益,而同期市

了超过 7%的年化收益,且相比基于历史波动率的策略,基于时变波动率的策略
具有更好的稳定性,捕捉更多的套利机会,得更高的风险整收益,
统计套利策略构建提供了新的思路

ABSTRACT
Listed on April 16 in 2010, CSI300 futures have got the favor of many investors
and have become a mature future variety. Institutional investors in China are keen on
the low risk arbitrage trading in CSI300 future market, especially the stock index
futures and spot arbitrage with high robustness. But since 2011, the CSI300 future
market has been relatively mature, opportunity of future and spot arbitrage is not much,
which seriously restrict the arbitrage activity of arbitrage funds. Therefore, digging new
arbitrage strategies becomes the urgent topic.
The calendar spread arbitrage of CSI300 futures is a new direction of arbitrage
activity. Especially with the development of systematic trading mode, and statistical
arbitrage has become the main hedge strategy in quantitative investment field, the study
of statistical arbitrage in the CSI300 future market has very vital significance, whether
on the test of market efficiency, or for the supervision and administration of stock index
futures, or for investor’s program trading.
In this paper, 5 minutes high-frequency closing price data of CSI300 futures is
selected as study object. First, we study the relationship of the recent month consecutive
contract and the next month consecutive contract with co-integration theories, and
outcome shows that there is a long-term equilibrium relationship between them, so they
can be used to construct co-integration arbitrage. Based on the theory of cost of carry
model, we study factors that could cause changes of the spread between these two
contracts, outcome shows that risk-free interest and dividend yield do have significant
influence on spread fluctuations and they are the granger causality of the spread
changes. Altogether, risk-free interest and dividend yield can explain 20% of the spread.
For more in-depth analysis of the spread, then spread is decomposed into two parts
——mean central and random disturbance. Different from previous research, EWMA
method is used in this paper to estimate the mean central. Related parameters are
determined afterwards through sensitivity analysis and Monte Carlo simulation, so a
general statistical arbitrage model is constructed on the sample data. Empirical results of
the strategy show that we can get 16.71% accumulated earnings in a year within the
sample, while the market’s earning is minus 25.02% in the same period, which fully
embodies the advantages of statistical arbitrage regardless of the influence of market
overall trend.
In addition, considering the time-varying variance characteristics of spread
fluctuations, we base our statistical arbitrage model on sample data, and two different
strategies are built for data out of the sample period. One is based on constant historical
volatility; the other is based on time-varying volatility which is produced by using
AR(3)-GARCH(2,1) model. Results show that the statistical arbitrage strategy can still
earn more than 7% of the annual income outside the sample, and compared to the
constant historical volatility, strategy based on time-varying volatility has better
stability, yields more arbitrage opportunities and is expected to obtain a higher risk
adjusted returns, which provides a new idea for the construction of statistical arbitrage
strategy.
