Value at risk. 2.4 Ordinary Interpolation. Interpolation is any procedure for fitting a function to a set of points in such a manner that the function intercepts each of the points. Consider m points ( x[k], y[k]) where x[k] n, y[k] , and the x[k] are distinct. We wish to construct a function f : n → such that y[k] = f ( x[k]) for all k.

This paper describes how the VaR is computed in practice, and gives a short overview of value at risk history. 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: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.To specify a value-at-risk metric, we must identify three things: The period of time over which a possible loss will be calculated—1 day, 2 weeks, 1 month, etc. This is called the value-at-risk horizon. In our example, the value-at-risk horizon is one trading day. A quantile of that possible loss. In the example, the portfolio’s value-at ...

The unfortunate truth is that historical simulation is popular, at least among banks. Pérignon and Smith ( 2010) report that, of banks that disclosed their methodology for calculating value-at-risk in 2005, 73% used historical simulation. Most of the rest—14%—used value-at-risk measures with Monte Carlo transformation procedures.
