Value at risk.

Jan 1, 2010 · Thus the value of the investment at the specified risk level of 0.05 is 3.42. The interpretation is that there is a 0.05 probability that things would be worse than the value at this risk level. Thus the greater the degree of assurance, the lower the value at risk return. The value at the risk level of 0.01 would only be 0.694609. 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: 风险价值. 風險價值 （英語： Value at Risk ，缩写： VaR ）， 资产组合 在持有期间内在给定的 信賴區間 内由于市场 价格 变动所导致的最大预期损失的数值。. 由此衍生出来的“风险价值”方法是 风险管理 中应用广泛、研究活跃的 风险 定量分析 方法之一。. Without default risk, the price of this bond at date t is (6.3) P t ( F) = ∑ h = 1 ∞ F t + h B ( t, t + h). The bond price is derived by treating a fixed income bond as a portfolio of zero coupon bonds and by applying the arbitrage free condition. In the presence of default risk, the bond price will decrease.
