问题如下：

Tim, an analyst of an investment company forecasts the return and deviation of below securities. Based on these information, which statement is most correct:

选项：

A.

Security A has the least amount of market risk.

B.

Security B has the least amount of market risk.

C.

Security C has the least amount of market risk.

解释：

B is correct.

The beta value of security A is=ρAmδAδm=1.4

The beta value of security B is =ρBmδBδm=1.33

The beta value of security C is=ρCmδCδm=1.5

Security B has the lowest beta value, therefore, it has the lowest amount of market risk.

market risk为什么用B算

嗨，从没放弃的小努力你好：


这里的市场风险就是相当于系统性风险。而不是市场组合的市场风险。还是要区分一下子。

嗨，从没放弃的小努力你好：


市场组合的市场风险β=1，并不代表所有组合的β都是1啊。可以看一下我截图的beta的定义，好好理解一下，他是相对于市场组合的敏感程度，比如一个组合的β=1.3，说明大盘涨1%，这个组合涨1.3%。

Bm=1，市场风险不都是一样的吗

嗨，从没放弃的小努力你好：


因为β就是衡量市场风险的。

NO.PZ2018070201000094 问题如下 Tim, analyst of investment company forecasts the return anviation of below securities. Baseon these information, whistatement is most correct: A.Security A hthe least amount of market risk. B.Security B hthe least amount of market risk. C.Security C hthe least amount of market risk. B is correct.The beta value of security A is=ρAmδAδm=1.4The beta value of security B is =ρBmδBδm=1.33The beta value of security C is=ρCmδCδm=1.5Security B hthe lowest beta value, therefore, it hthe lowest amount of market risk. Market Risk 难道不应该指的是系统性风险吗？ 比如加息等。我看了看别的同学问的问题，我觉得助教回答不是很靠谱，“这道题的市场风险就是非系统性风险”。 是教材里面明确这么写的吗（Market Risk = B)？如果是的话那我会改变我的立场，如果教材里没有明确写，我会觉得加息等行为是市场风险。
