In the empirical analysis part, statistical descriptions on the sample funds are made firstly, which show that the actual distribution of each sample fund"s daily net value return possesses the characteristic of leptokurtosis. So it is necessary to add student T distribution and GED to capture such leptokurtosis characteristic other than normal distribution. Secondly, ARCH test shows that there exists volatility clustering in each sample fund"s daily net value return, so GARCH related models should be used to describe such volatility clustering characteristic.
实证分析部分首先对样本基金进行统计描述,得出其收益序列均存在尖峰厚尾特征,不服从正态分布,因此有必要在下面的VaR计算中加入T分布和GED分布来捕捉这种尖峰厚尾特征;并且经ARCH检验后得出收益序列存在明显的波动聚集性的特征,因此可以选择GARCH类模型来描述这种特性,经过模型筛选,得出最适合我国开放式股票型基金的收益波动性模型为GARCH(1,1)模型。

The test conclusions indicates that the long-term equilibrium relationship between SZZS series and its optimal series is not significant, but the short-term dynamic relationship is comparatively significant; since 2007, the ratio of variance to its mean is more than 0.4, which implies that SZZS is deviated from its optimal level to a great extent, which is the basic feature of bull market or bear market, and this also verify the robustness of these conclusions.
实证结论表明,上证指数序列与其均值序列的长期均衡关系不显著,但短期的动态关系比较明显;从2007年开始,上海股市的标准差/均值相当大,超过了0.4,这意味着上证指数偏离其均值的程度较大,这是牛、熊市的基本特征,这也印证了本文结论的强健性。
