We extend the example given in the section “Non-Parametric VaR” of blog Value at Risk. In particular, as long as the annual VaR (in this case we use VaR (zero), however VaR (mean) would also work) has been computed, we compute the average value of losses beyond this level. Note ...
Conditional Value at Risk (CVaR) Formula Since CVaR values are derived from the calculation of VaR itself, the assumptions that VaR is based on, such as the shape of the distribution of returns, the cut-off level used, the periodicity of the data, and the assumptions aboutstochastic volatilit...

Value-at-Risk VaR has a role in the approach, but the emphasis is on Conditional Value-at-Risk CVaR, which is known also as Mean Excess Loss, Mean Shortfall, or Tail VaR. By de nition with respect to a speci ed probability level , the -VaR of a portfolio is the lowest amount such...
1) provide a formula for calculating t VaR as a function of variables known at time t-1 and a set of parameters that need to be estimated; 2) provide a procedure (namel y, a loss function and a suitable optimization algorithm) to ...
In this study, we propose a new definition of multivariate conditional value-at-risk (MCVaR) as a set of vectors for arbitrary probability spaces. We explore the properties of the vector-valued MCVaR (VMCVaR) and show the advantages of VMCVaR over the existing definitions particularly for dis...
