Expected shortfall considers loss beyond the VaR level and is shown to be sub-additive, while VaR disregards loss beyond the percentile and is not sub-additive.1 In this paper, we compare expected shortfall with VaR in three aspects: their estimation errors, their decomposition into risk factors, and their ...
Expected shortfall (ES) is a risk measure—a concept used in the field of financial risk measurement to evaluate the market risk or credit risk of a portfolio.
