【摘要】 本文使用广义的双曲分布(GH分布),选取了深沪两市共11只股票,对股票价格的日对数收益率的概率分布进行了深入的研究。在所有的情形,GH分布都给出了非常令人满意的拟和。这表明GH分布作为股票日对数收益率的分布,在中国股市是一个很好选择。从而,以GH分布为基本模块构造风险管理模型和金融衍生产品定价公式在理论和实际应用中都将有重要意义。本文给出了相应的风险(VaR)值的Matlab计算程序。

【Abstract】 This paper has studied the distributions of the log returns of the Chinese stock market, using the Generalized Hyperbolic Distributions (GH) as the reference distributions. The empirical results shows that in almost all the cases, both Normal Inverse Gaussian (NIG) distribution and the Hyperbolic distribution can fit the data very well. This suggests that using GH as building block, we may hopefully get some more realistic models in Value at Risk modelling and option pricing. Some empirical studies on this are also reported in this paper.
