摘要
在阐述了投资组合边际VaR、成分VaR和增量VaR之间相互关系的基础上,给出了资产收益率服从非正态分布下投资组合分解的一种新方法,结果发现它与正态方法下投资组合分解的结论一致,并结合实证研究验证了结论的正确性.
The mutual relationships among marginal VaR, component VaRand incremental VaR were given. A new method for decomposing the portfolio VaR based on the non-normal distribution was given, whose results agree with those obtained by decomposing the portfolioVaR under normal distribution. Finally, the validity was examined by empirical research.
