问题如下:

Adding domestic small-cap equities to TEF’s portfolio will most likely result in:

选项:

A.

overlapping asset classes.

B.

duplicating risk exposures already present.

C.

diminished opportunities for applying active strategies.

解释:

Asset classes should be diversifying. For risk control purposes, an included asset class should not have extremely high expected correlations with other asset classes or with a linear combination of other asset classes. Otherwise, the included asset class will be effectively redundant in a portfolio because it will duplicate risk exposures already present. In general, a pairwise correlation above 0.95 is undesirable.

Asset classes should be mutually exclusive. Overlapping asset classes will reduce the effectiveness of strategic asset allocation in controlling risk and could introduce problems in developing asset class return expectations.

Asset classes as a group should make up a preponderance of world investable wealth. From the perspective of portfolio theory, selecting an asset allocation from a group of asset classes satisfying this criterion should tend to increase expected return for a givenlevel of risk.

The inclusion of more markets expands—not diminishes—the opportunities for applying active investment strategies.

嗨,努力学习的PZer你好:


同学你好:


这道题考察了选择资产类别的5条标准中的知识点。

 TEF’s portfolio 中,大类的资产类别包含股票、债券和另类投资,所以满足mutually exclusive,也就是资产大类之间应该是互斥这一条,所以 asset classes 并没有 overlapping。

而在股票这个大类资产中,现在已经有国内股票和全球股票,这已经包含了股票的全部,但是如果再加入domestic small-cap equities,就违反了Asset classes should be diversifying 这一条,应为现有的国内股票,已经包含了大盘股和小盘股,如果再加入国内小盘股,就会增加股票资产的现有风险敞口,并没有起到风险分散化的作用。

但是在现有的资产配置方案中,调整某一类资产的权重,例如题中说的,增加国内小盘股,这是属于TAA,是一种积极的投资管理策略,也就是增加了积极投资管理策略的机会。
