摘 要
沪深 300 股指期货2010 416 日在中金所上市后,受到了广大投资
的青睐,目前已经成为一个较成熟的期货品种。机构投资者在股指期货的投资上
往往热衷于风险较低的套利交易,尤其是稳健性较高的基差套利交易。但自 2011
年以来,沪300 股指期货市场已经较为成熟,基差套利机会并不多,这严重制
约了套利资金的活动。因此,挖掘新的套利机会成为当前亟待解决的课题。
股指期货的跨期套利是套利投资的新方向,随着交易系统的深入发展,统计
套利已成为量化投资领域的旗舰对冲策略。对我国股指期货统计套利的研究,对
于资本市场有效性的探讨、股指期货的监督管理、投资者程序化交易的启示,都
具有非常重要的意义。
本文采用 1分钟高频收盘价格数据,对我国沪深 300 指期货当月连续合
和下月连续合约进行研究。首先运用协整理论对两合约间的长期均衡关系进行分
析。协整检验结果表明当月合约和下月合约之间存在长期均衡关系,可以用来构
建协整套利模型。同时,本文在基于持有成本定价理论的基础上,对价差的影响
因素进行分析表明:无风险利率和股息率对价差波动具有明显的影响,是价差变
化的 Granger 因果原因,其合计可以粗略解释 20%的价差波动。
为了更符合实际交易应用,本文接着对价差重新进行了定义,将价差分解为
均值中枢和随机扰动项两部分。与以往研究不同,本文采用指数加权移动平均法
对价差的均值中枢进行估计,通过敏感性分析以及蒙特卡罗模拟确定衰减因子及
最优
k
值等相关参数。对样本内 1分钟数据建立套利模型,结果表明:相比于-32%
的同期市场收益率,本文使用的统计套利策略在样本内获得了约 16.71%的年化收
益率,这充分体现了统计套利的市场中性优势。
考虑到金融时间序列的时变方差特性,对于样本外数据,以样本内建立的套
利模型为基础,通过基于历史波动率和基于时变波动率这两种方法来构造信号指
数和套利策略。采用 AR(3)-GARCH(2,1)对时变波动率进行建模。结果表明:基于
时变波动率的统计套利策略比基于历史波动率的统计套利策略具有更好的表现,
能捕捉更多的套利机会,有望获得更高的风险调整收益。

ABSTRACT
Since listed in CFFE on April 16th 2010, HS300 futures have got the interest of
financial market and have become a mature future variety so far. Institutional investors
in China are always keen to the arbitrage trading with low risk in index future market,
especially the spot-future arbitrage with high robustness. But there is less and less
opportunity of spot-future arbitrage since HS300 future market became relatively
mature in 2011 , which restrict the activity of arbitrage funds seriously. Therefore,
exploring new arbitrage strategies becomes the urgent issue.
The calendar spread arbitrage of HS300 futures is a new arbitrage strategy.
Companied by the development of systematic trading mode, statistical arbitrage has
become the main hedge strategy in quantitative investment field. The study of statistical
arbitrage in the HS300 future market is significant, no matter to the test of market
efficiency, or to the supervision and administration of authority, or to the inspiration of
investors program trading.
In this paper, 1 minute closing price data of HS300 futures is selected as study
sample. Firstly, we study the long-term relationship of the current month consecutive
contract and the next month consecutive contract based upon co-integration theories.
The test shows that a long-term equilibrium relationship exists between the two
contracts. So they can be used to build co-integration arbitrage model. At the same time,
we study the factors that cause changes of the price spread between the two contracts on
the ground of cost of carry model. The study shows that risk-free interest and dividend
yield do have significant influence on the spread fluctuations and they are the granger
causality of the spread changes.
For more in-depth analysis, the spread is decomposed into two parts——mean
central and random disturbance. Different from previous researches, EWMA model is
used in this paper to estimate the mean central. Related parameters are determined by
sensitivity analysis and Monte Carlo simulation. The general statistical arbitrage model
build on the sample data shows that we could obtain a 16.71% accumulated annual yield
within the sample, while the market yield is -32% within the same period, which fully
demonstrates the neutral market advantages of the statistical arbitrage strategy.
Additionally, considering the time-varying variance characteristic of spread
fluctuations, we adopt two different strategies to describe the variance: constant
historical volatility and time-varying volatility which is calculated by
AR(3)-GARCH(2,1) model. Results show that compared to the constant historical
volatility, strategy based on time-varying volatility has better stability, more arbitrage
opportunities and higher expected risk adjusted returns.
