Python计算获得多资产投资组合的风险度量。 关键概念 随着价格的变动,投资经理所持有的市场价值也会发生变化。后者就是所谓的市场风险,衡量它的最流行的方法之一是定义为风险价值。风险本身被看作是实际收益和期望收益之间的差异,两者可能不同。如果它们相等,投资被认为是无风险的。同时,它不能有违约风险,也不能有再...
Value at risk over n-day time period What if we wanted to calculate this over a larger window of time? Below we can easily do that by just taking our 1 day VaR and multiplying it by thesquare root of the time period(this is due to the fact that the standard deviation of stock retu...
