问题如下：
Judge which industry is most attractive from a valuation perspective.
选项：
解释：
Based on the above analysis, the Swiss Healthcare Industry would have the highest expected return. However, that expected return reflects compensation for systematic risk. Based on the data provided we cannot conclude which industry is most attractive from a valuation standpoint.
解析：
根据上述分析，瑞士医疗行业的预期回报率最高。然而，预期收益反映了对系统性风险的补偿。根据所提供的数据，我们无法从估值的角度得出哪个行业最具吸引力的结论。
我看之前两位同学提问， 都问为啥不能用Sharpe Ratio？
回答没太看懂。。
现在我们等于已经算出来 Risk Premium了，也就是E（Ri）
然后题目里也给了standard deviation of 大盘，of各个行业
那不就是可以求sharpe ratio了吗？（=E（Ri）/ standard deviation of 各个行业）？哪里不对呢？
谢谢老师！！
