you don’t know how much the loss could be in the remaining 5% of the cases. In addition, it does not account for “tail risk" or extreme events that may lead to larger losses. This brings us to yet another statistical risk measure called Expected Shortfall (ES), which fixes this ...

For an example of an analytic ES calculation with a t-distribution, see Expected Shortfall Estimation and Backtesting. Alternatively, calculating the ES by averaging VaR values computed with a t distribution is essentially identical to the workflow in this example, as is calculating the ES by ...
For example, VaR at 99.5% confidence level is approximately 2.58 times the standard deviation, while expected shortfall at the same confidence level is approximately 2.89 times the standard deviation.1 The assumption that financial returns are Gaussian is often criticized and it may lead to an ...
G-expected shortfall (G-ES), which is a new type of worst-case expected shortfall (ES), is defined as measuring risk under infinite distributions induced by volatility uncertainty. Compared with exta...

Findings - The presence of autocorrelation changes the values of most of the correlation parameters used in the calculation of the Expected Shortfall (ES) of the Risk Bearing Capital - in some cases the cross-asset correlation parameters double. Once the presence of smoothing is accounted for, ...
