We might define such horizons in terms of actual days or trading days. To avoid having the end of a horizon fall on a weekend or holiday, we adopt the latter convention. A “1-day horizon” comprises 1 trading day. A “5-day horizon” comprises 5 trading days.Ideally, we look for a number (or set of numbers) that expresses the potential loss with a given level of confidence, enabling the risk manager to adjudge the risk as acceptable or not.

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: VaR percentile (%). For instance the typical VaR numbers are calculated as a 95th percentile or 95% level which is intended to model the deficit that could ...Still, value-at-risk remained a specialized tool known primarily to risk managers at financial firms.
