问题如下:
Fox is in the process of hiring an asset allocation analyst and has just completed interviewing two candidates, Ambrose Kelly and Catherine Trainor, for the position.
Fox mentioned to
the candidates that when dealing with strategic asset allocation, investors
often had difficulty understanding the relevant characteristics of asset classes.
They responded:
Kelly: I like to stress to
clients that asset classes should have high within-group correlations but low
correlations with other classes. In addition, because investors need to
rebalance to a strategic asset allocation, asset classes need to have both
sufficient liquidity and low transaction costs.
Trainor: It is important that
asset classes should be diversifying. I always look for low pairwise
correlations with other asset classes.
In the candidates’ responses to Fox regarding the relevant characteristics of asset classes, the statement that is least accurate is: (2018 Mock AM)
选项:
A.
Kelly’s regarding correlations.
B.
Trainor’s.
C.
Kelly’s regarding rebalancing.
解释:
B is correct. Although Trainor is correct that asset classes should be diversifying, low pairwise correlations with other asset classes is not sufficient. An asset class may be highly correlated with some linear combination of the other asset classes even when pairwise correlations are not high. Both of Kelly’s comments are correct: Asset classes should have high within-group correlations but low correlations with other classes. If liquidity and transaction costs are unfavorable for an investment of a size meaningful for an investor, an asset class may not be a suitable investment for that investor.
A is incorrect. Kelly’s first comment is correct about both the within-group and between class correlations.
C is incorrect. Kelly’s second comment is correct. The criteria that he is referring to is that asset classes should have the capacity to absorb a meaningful proportion of an investor’s portfolio. He is correct in saying that if liquidity and transaction costs are unfavorable for an investment of a size meaningful for an investor, an asset class may not be a suitable investment for the investor.
我理解T的statement考了很偏的知识点pair wise correlation 但是题目中并没有说“只”考虑 pair wise correlation
相比之下,Kelly 的statement 更不正确,即便是为了rebalance to SAA,也不能要求所有产品都有good liquidity;有的产品本身就是为了liquidity premium拿excess return用的,所以如果出现了不好的liquidity不应该直接放弃,而是应该扩大liquidity range 综合考虑
