ヾ(?°?°?)??你好同學(xué),
題目求的是超過“在險(xiǎn)價(jià)值100mil損失”的所有損失的加權(quán)平均值(expected value)
1 在險(xiǎn)價(jià)值:一定時(shí)間內(nèi),最小概率下的最大損失。例如1天內(nèi),有1%的可能性最少損失100美元(也可以說有99%的可能性最多損失100美元)
Value at risk (VaR) is a measure of the size of the tail of the distribution of profits on a portfolio or for an entity, which
Three elements: an amount stated in units of currency, a time period, and a probability
e.g. A VaR of $100 at 1% for one day means it is expected to lose a minimum of $100 in one day 1% of the time.
2
Conditional VaR (CVaR) is the weighted average of all loss outcomes in the statistical distribution that exceed the VaR loss.
條件在險(xiǎn)價(jià)值:超過“在險(xiǎn)價(jià)值”的所有損失的加權(quán)平均值。
