Robust backets for expected shortfall
Webits de nition. We compare some of the de nitions of Expected Shortfall, pointing out that there is one which is robust in the sense of yielding a coherent risk measure regardless of the underlying distributions. Moreover, this Expected Shortfall can be estimated e ectively even in cases where the usual estimators for VaR fail.

WebExpected Shortfall (ES), also known as Conditional Value-at-Risk (CVaR), is a coherent measure of risk which considers losses exceeding the corresponding Value-at-Risk (VaR). As ES remedies the tail risk and non-sub-additivity, problems VaR inherently su ers (?), it has been attracting more and more attention in the eld of risk management. WebJan 1, 2016 · Jan 2016.

WebExpected Shortfall or CvaR indicates the average loss when the loss exceeds the VaR level. If we are measuring VaR at the 95% confidence level, the expected Shortfall would be the average loss in the 5% cases where the fund exceeds its VaR. In the example above, for the fund with losses limited to $105, and a VaR of $100, its expected Shortfall ...
