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 ...

Did you know?
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. The "expected shortfall at q% level" is the expected return on the portfolio in the worst $${\displaystyle q\%}$$ of cases. ES is an … See more If $${\displaystyle X\in L^{p}({\mathcal {F}})}$$ (an Lp space) is the payoff of a portfolio at some future time and $${\displaystyle 0<\alpha <1}$$ then we define the expected shortfall as See more The expected shortfall $${\displaystyle \operatorname {ES} _{q}}$$ increases as $${\displaystyle q}$$ decreases. The 100%-quantile expected shortfall $${\displaystyle \operatorname {ES} _{1}}$$ equals negative of the expected value of … See more • Coherent risk measure • EMP for stochastic programming – solution technology for optimization problems involving ES and VaR See more Example 1. If we believe our average loss on the worst 5% of the possible outcomes for our portfolio is EUR 1000, then we could say our expected shortfall is EUR 1000 for the 5% tail. Example 2.

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 expected return (loss) based on the x% worst occurrences. As such, it relationship towards VaR becomes more clear.
