摘要: 本文在简要介绍投资组合VaR的概念及计算方法后对组合VaR进行了具体的分解。在阐述了边际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为正态和非正态分布假设下这三种类型VaR的计算方法,从而为资产组合管理者提供了更多有关投资组合市场风险的信息。

关键词: 投资组合VaR, 成分VaR, 边际VaR, 增量VaR, 条件均值估计

Abstract: In this paper,we carry out a concrete decomposition on protfolio Value-at-Risk after presenting briefly the conception and computational method of protfolio VaR Following that,we deduce the estimative methods of the marginal VaR,component VaR and incremental VaR,which are held with the hypotheses of normal and non-normal distributions respectively,based on the mutual relationships of the three types VaR All these discussions provide more market risk information on protfolio for its managers.

Key words: Portfolio VaR, component VaR, marginal VaR, incremental VaR, estimation by conditional mean
