Given that the fund mandate requirement is for a short-term return in excess of the risk-free rate, the Sortino ratio is a more appropriate measure because it penalizes returns below a specific return—in this case, 1.5% above the risk-free rate.B is incorrect. The Treynor ratio penalizes returns below the risk-free rate. It will not measure the fund’s ability to meet the requirement of a short-term return in excess of the risk-free rate.C is incorrect. The information ratio evaluates the portfolio return relative to a benchmark. It will not measure the fund’s ability to meet the requirement of a short-term return in excess of the risk-free rate.

同學(xué)你好,
這題是根據(jù)客戶的investment mandate,哪個appraisal measure最合適。
客戶說他有 a preference for a short-term return that is 1.5% above the risk-free rate. 因此可以理解為rf+1.5%就是客戶可以接受的最低收益率即MAR。而sortino ratio分子上的收益就是Rp-MAR,而分母上算的是低于MAR的半標(biāo)準(zhǔn)差,即該指標(biāo)只懲罰低于MAR的收益的波動。因此,根據(jù)客戶的要求,sortino ratio是最合適的。
如果答疑對你有幫助,【請采納】喲~。加油,祝你順利通過考試~

要求的是1.5%above risk free rate,而該指標(biāo)只懲罰低于MAR的收益的波動。這兩點沒懂

1、 a preference for a short-term return that is 1.5% above the risk-free rate. 說明客戶要求的回報率是無風(fēng)險收益率+1.5%,那么這個就是客戶能接受的最低的收益率,即MAR。
2、這些業(yè)績衡量指標(biāo)衡量基金經(jīng)理表現(xiàn)時是越大越好的。而分母代表的風(fēng)險就是“懲罰”這個指標(biāo)的,因為分母越大這個指標(biāo)越小。
例如sortino ratio它的分母是下行標(biāo)準(zhǔn)差,即只有低于MAR的收益率才會用于算標(biāo)準(zhǔn)差,因此sortino ratio 只“懲罰”低于MAR的收益率。
