Value-at-risk, also know as VaR, is a metric introduced by JP Morgan indicating the total risk of a portfolio in a single number. In technical terms, value-at-risk indicates that with a certain probability, over a given period of time, the loss of a portfolio will not be greater than x. For example, the VaR for 10 days with 99% could be 1,000,000. 4.3.1 Samples. Many people have an intuitive understanding of samples that does not conform to the technical definition, which is quite formal.
