Value at risk (VaR) is a financial metric that you can use to estimate the maximum risk of an investment over a specific period. In other words, the value at risk formula helps you to measure the total amount of potential losses that could happen in an investment portfolio, as well as ...
下面我们讨论几个模型,这些模型中,收益率仍然服从正态分布, Value-at-Risk的计算,象前面有关章节一样,可以直接计算,唯一需要注意的是将下标t 加入到均值与方差。 1、简单移动平均法 考虑收益率方差变化的最简易方法是应用最新的数据估计标准差,例如不是利用象我们在6.1节中应用最近3年的收益率数据而是应用最近若干...

Thehistorical methodlooks at one’s prior returns history and orders them from worst losses to greatest gains—following from the premise that past returns experience will inform future outcomes. See “Value at Risk (VaR) Example” below for the formula and how it’s calculated. Variance-Covarian...
There are several methods to calculate VaR, each with a different formula, The most simple method to manually calculate is the historical method (shown below), where m is the number of days from which historical data is taken and viis the number of variables on day i. Value at Risk formu...
