Value at risk

3.2 Prerequisites. We assume familiarity with basic notation and concepts from probability. If E is an event, we denote its probability Pr ( E ). You should be familiar with random variables and random vectors. A random vector X can be thought of as an n -dimensional vector of random variables Xi all defined on the same sample space..

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: The risk management system is one of the key requirements for high-risk AI systems (Article 10) and one of the obligations for general-purpose AI models with …

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.
