Value at risk.
Value at risk is a useful concept in terms of assessing probabilities of investment alternatives. It is a point estimator, like the mean (which could be viewed as the value at risk for a probability of 0.5). It is only as valid as the assumptions made, which include the distributions used in the model and the parameter estimates.
Value at Risk (VaR) A measure of loss for investments, the VaR model analyses the volatility of a portfolio.

Value-at-risk metrics first emerged in finance during the 1980s, but they were preceded by various other PMMRs, including Markowitz’s ( 1952) variance of simple return. Even earlier, Leavens ( 1945) published a paper describing the benefits of diversification.

The Value at Risk (VaR) measures the risk affecting the market value V of a given position. Lh ≡ V0 – Vh is the loss between 0 and h, and FL its distribution function ( FL ( x) = Prob ( Lh ≤ x )). The VaR at the horizon h and with probability level p, VaR (h,p), is the p - quantile of Lh:

A new approach to optimizing or hedging a portfolio of financial instruments to reduce risk is presented and tested on applications. It focuses on minimizing conditional value-at-risk (CVaR) rather than minimizing value-at-risk (VaR), but portfolios with low CVaR necessarily have low VaR as well. CVaR, also called mean excess loss, mean ...An alternative measure of risk is the conditional value-at-risk (CVaR), also called superquantiles.

Value-at-risk aims to measure the potential loss on a portfolio that would result if relatively large adverse price movements were to occur.
