问题如下:
Basing your answers only upon the data presented in the table above and using the international capital asset pricing model—in particular, the Singer–Terhaar approach—estimate the expected risk premium for the following:
i. Swiss Health Care Industry
ii. Swiss Watch Industry
iii. Swiss Consumer Products Industry
解释:
Using the formula
we can solve for each expected industry risk premium. Te term in brackets is the Sharpe ratio for the GIM, computed as 3.5/8.5 = 0.412
i. RPHealthcare = (12)(0.7)(0.412) = 3.46%
ii. RPWatch = (6)(0.8)(0.412) = 1.98%
iii. RPConsumer Products = (7.5)(0.8)(0.412) = 2.47%
解析:
注意到本题假设市场完全整合,所以我们无需再按权重求解市场整合程度。并且该题不涉及对于资产流动性的补偿。因此我们直接套用公式RPiG=ρi,GM σi(RPGM/σGM),其中Sharpe ratio =3.5/8.5 =0.412. 。
那么,
i. RPHealth Care = (12)(0.7)(0.412) = 3.46%
ii. RPWatch = (6)(0.8)(0.412) = 1.98%
iii. RPConsumer Products = (7.5)(0.8)(0.412) = 2.47%
