Value at risk.

Portfolio risk measures such as value-at-risk (VaR) are traditionally measured using a buy-and-hold assumption on the portfolio. In particular, ten-day marketrisk capital is commonly measured as the one-dayVaR scaled by the square root of ten. While this scaling is convenient for obtaining n-day VaR numbers from onedayVaR, … Value-at-risk (VAR) Value-at-risk is a statistical measure of the riskiness of financial entities or portfolios of assets. It is defined as the maximum dollar amount expected to be lost over a given time horizon, at a pre-defined confidence level. For example, if the 95% one-month VAR is $1 million, there is 95% confidence that over the next ...

Value at Risk. Using imprecise language, the Value at Risk – abbreviated as VaR – of a particular asset is just an amount, for example $1M, which represents the worst possible future loss sustained by that asset.
