WebbChapter 11 Historical Simulation 11.1 Motivation. One of the three “methods” early authors identified for calculating value-at-risk was called historical simulation or historicalvalue-at-risk.A contemporaneous description of historical simulation is provided by Linsmeier and Pearson ().Updated to reflect our terminology and notation, it reads: WebbFrom historical data, we find that the worst increase in yields over a month at the 95% is 0.40%. The worst loss, or VAR, is then given by Worst Dollar Loss = Duration x 1/(1+y) x Portfolio Value x Worst Yield Increase VAR = 4.5 Years x (1/1.05) x $100m x 0.4% which is also $1.7 million!

In this thesis, which is based on paper [4], section 2 is allocated to the explanation of the VaR. In section 3 we will explain concepts of HS and FHS as a new generation of VaR measurement methods. In section 4 we
WebbIf you use the most basic historical simulation approach, as your historical window shifts, large losses or returns at the edge of the window will no longer be in your data-set and can cause a significant jump in the Var (this is called ghosting) which in very undesirable Guassian/Parametric/Delta Normal/Variance-Covariance (has many names) Pros: WebbVaR Methods and Formulas The variance-covariance method, the Monte Carlo simulation, and the historical method are the three methods of calculating VaR. But first, let us understand how to calculate the potential risk through each of the three ways: #1 – Variance-Covariance Method
WebbFiltered Historical Simulation VaR can be described as being a mixture of the historical simulation and EWMA methods. Returns are first standardized, with volatility estimation weighted as in EWMA VaR, before a historical percentile is applied to the standardized return as in the historical model. From the graphs it is easy to spot that
