ES不是超过VaR的平均损失吗？

NO.PZ2018122701000006问题如下 After estimating the 99%, 1-y Vof a bank’s portfolio to US1,484 using historicsimulation with 1000 past trang ys, you are concerneththe Vmeasure is not proving enough information about tail losses. You ci to re-examine the simulation results ansort the simulateily P&L from worst to best giving the following worst 15 scenarios: Whis the 99%, 1-y expecteshortfall of the portfolio? US433 US1,285 US1,945 US2,833 C is correct. 考点 ： ExpecteShortfall 解析 ： ExpecteShortfall = Average of the worst 10 ily P&L= US1945 请问ES不是大于VaR的取平均吗？为什么还要算第10个数（Var）？

US1,285 US1,945 US2,833 C is correct. 考点 ExpecteShortfall 解析 ExpecteShortfall = Average of the worst 10 ily P&L= US1945 是否应该取1960和1751的平均值？
