In the candidates’ responses to Fox regarding the relevant characteristics of asset classes, the statement that is least accurate is:
选项:
A.Kelly’s regarding correlations. B.Trainor’s. C.Kelly’s regarding rebalancing.解释:
SolutioB 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.
老师请问,这句话应该修改成什么呢?I always look for low pairwise correlations with other asset classes.
