问题如下:
Adding domestic small-cap equities to TEF’s portfolio will most likely result in:
选项:
A.overlapping asset classes.
duplicating risk exposures already present.
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.
我之前投资中盘股大盘股,相当于之前的主动策略是不看好小盘股,现在我小盘股也投资了,相当于投资类别更大了,风险更分散了,相当于之前投资中大盘股ETF,现在我直接投资一个全指ETF,所以就是类似被动管理了,因为我没有一个特殊的偏好了。
请问这样理解有什么问题?
