您好~看到您在知道中为网友解答如下题目As given on the Morningstar website,the mean return for Fidelity Leveraged Company Stock is 17.98 percent with a standard deviation of 10.02 percent,while the mean return for Baron Opportunity Retail Stock is 16.43 percent with a standard deviation of 12.23 percent.Which stock do you buy?(Which is riskier than the other one?)
我想知道问句会买哪支股票,为什么后面还要写哪个风险更高呢?难道不是风险越低才会买吗?

我想括号里面是一个提示,让学生从风险角度分析,决定买哪个股票.
