Since Leptokurtosis, skewness and fat-tail are always used to depict market risk, this paper introduces the improved Laplace distribution to risk management of stock portfolio.

在改进型Laplace分布的基础上提出了基于Copula方法与Monte-Carlo模拟的VaR算法。

In this paper, we improve the EWMA Futures Margin based on normal distribution assumption and propose a new model of futures margin based on skewed EWMA estimator which based on the asymmetric laplace distribution that is sound to capture leptokurtosis and fat-tail.

本文是对建立在正态分布假设的EWMA期货保证金模型的改进。文中引入基于非对称Laplace分布发展起来的有偏型EWMA方法，建立了新的期货交易保证金模型，较好地反映了期货合约价格序列有偏、厚尾的现象。

And the evaluation effects of China's Stock Market's volatility by different ARCH models from different point of view are compared. In addition, by using two mixed distribution models, the leptokurtosis and fat-tail of stock return are examined. Based on the above analysis, an improved Laplace distribution model is proposed. Furthermore, the root generating non-Gaussian return distribution of the stock market ? is expounded from the perspective of both economy and capital market.

首先分别从分布和波动性模型出发，研究中国股票市场收益分布特征与波动性特征：从ARCH族模型出发，考察了中国股票市场波动性的异方差、集群性、杠杆效应以及长记忆性特征；从两个混合分布模型出发，结合随机模拟考察了收益分布的尖峰、厚尾和偏态特征，并提出了改进型LapJace分布。

Since Leptokurtosis, skewness and fat-tail are always used to depict market risk, this paper introduces the improved Laplace distribution to risk management of stock portfolio. Empirical results show, improved Laplace distribution and asymmetric Laplace distribution are similar for estimating Leptokurtosis, while improved Laplace distribution is better for estimating skewness.In order to analyze the correlation between return distribution and volatility, the thesis uses ARCH-M Models to simulate the return series of China's Stock Market and developed markets ao as to discover the relation between investment return and time-varying risk.

对尖峰、厚尾、偏态的刻画有助于正确估计市场风险，本文将改进型Laplace分布引入到股票组合的风险管理中，实证结果发现，改进型Laplace分布和非对称Laplace分布对尖峰、厚尾的刻画效果接近；而非对称Laplace分布对负偏性考察不足，改进型Laplace分布的拟合结果能够准确地反映股指收益的负偏态，这也正是改进型Laplace分布相对于传统的非对称Laplace分布的优势所在。
