问题如下:

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.

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.

不应该是rebalance to tactical asset allocation 嘛

嗨,从没放弃的小努力你好:


同学你好:


你可能是对SAA和TAA彼此之间的区别和联系,还有些模糊,我这里再解释一下。


SAA (Strategic)是和tactical AA相对的,SAA是长期战略,TAA是短期的在可控范围内的战术偏离。

 SAA(strategic Asset allocation)战略资产配置,主要的就是指的大类的资产类别之间进行配置,而配置的基础就要根据客户对收益和风险,投资期,特殊偏好等特征来进行。

在做TAA(Tactical Asset allocation)战术资产配置,是要在已经配置好的SAA基础上,如果投资经理能够抓到短期机会,就会对SAA的配置权重做出短期的变化,从而获得α。但是在最初设置的SAA里,会有一个policy weight, 这是一个特定数字,比如说,投入股票的比重为40%,但同时也会设定一个可以上下浮动的范围,比如说,上下浮动5%,这也就是后期投资经理发现短期机会,进而对之前的policy weight进行调整时的范围限制,如果预计未来短时间内股票的预期收益会更高,那就把股票的比重更改为45%,反之就是35%。而这个rebalancing range,就是上下浮动5%这个浮动范围。


所以,Kelly的评论中,“In addition, because investors need to rebalance to a strategic asset allocation”这句话是没有问题的。

Kelly: I like to stress to clients thasset classes shoulhave high within-group correlations but low correlations with other classes. In aition, because investors neeto rebalanto a strategic asset allocation, asset classes neeto have both sufficient liquity anlow transaction costs.Trainor: It is important thasset classes shoulversifying. I always look for low pairwise correlations with other asset classes.老师,题目中问的是least 准确性,也就找谁说的不对。kelly说“asset classes neeto have both sufficient liquity anlow transaction costs.”但是如果投资 reestate 这类资产的话,不可能要求高流动性和低成本啊,他的说法为什么是对的?Trainor说“low pairwise correlations with other asset classes.”我看其他解答里,pairwise correlations是两两的相关性,也就是A与B、C要相关性低,且A与BC组合的相关性也要低,那他说的是low pairwise correlations,相关性低,这个说法为什么不对啊?
