老师，能不能帮我解释下组合管理第二课课后题16和18呀？我不理解什么是surplus at risk以及"when historical simulation fully revalues securities under rate and price changes that occurred during the scenario period, the results should be highly accurate."这句话

嗨，从没放弃的小努力你好：
同学你好，答案中有对概念进行解释：Surplus at risk is an application of VaR; it estimates how much the assets might underperform the liabilities with a given confidence level, usually over a year.surplus 是VAR的一个应用，研究的是在一定时间内一定置信区间下资不抵债的水平。Surplus at risk is an application
of VaR; it estimates how much the assets might underperform the liabilities with a given confidence level, usually over a year。课件的讲解如图
