WebThe expected shortfall (ES), also called the conditional value-at-risk, is a tail-risk measure used to accommodate some shortcomings of VaR. The expected shortfall calculates the … WebThe two formulas are given below: ES = E(L L > VaR) ES = 1 1− c ∫ 1 c qpdp ES = E ( L L > VaR) ES = 1 1 − c ∫ c 1 q p d p where, qp q p refers to the loss quantile corresponding to probability level p p. We can start with the first formula and through some simple math arguments eventually arrive at the second formula.

I have a question about how to compute the Expected Shortfall practically. I know from the theory that the ES is the conditional Expectation of the Loss distribution (conditional on the VaR) and that it is intrinsically greater than the VaR: ES_α = E [L L > VaR_α] Following this formula I have calculated the VaR in R using quantile (loss ... johannes nagel ceramics
