问题如下:

Basing youranswers only upon the data presented in the table above and using theinternational capital asset pricing model—in particular, the Singer–Terhaarapproach—estimate the expected risk premium for the following:

i. Swiss HealthCare Industry

ii. Swiss WatchIndustry

iii. SwissConsumer Products Industry

解释:

请问这题为什么不需要讨论correlation等于1的情况,再根据weight加权平均呢?有点分不清具体适用场景了

嗨,从没放弃的小努力你好:



首先,是因为题目没有给出关于市场整合的情况。

一般英文表述是DEGREE OF INTEGRATION。

也就是权重信息没给。想加权也加权不了。

其次,是这句Assume that the Swiss market is perfectly integrated with the world markets.

这句话就表明市场就是完全整合的,那直接用完全整合的公式去算就行了。
