Asset classes分类的特点

嗨，努力学习的PZer你好：

这一段是reading 5中的内容，我们先看它是资产分类的5个标准中的第4个。

The asset classes as a group should make up a preponderance of world investable wealth.

这句话意思是，资产类别作为一个group应该要尽可能全面得包含全世界的可投资资产。

这句话之所以同学难理解是因为make up a preponderance of 这个词组我们比较陌生，不能只单纯的看preponderance单词的意思。

我们品职在讲义中把这个标准总结为cover the majority of world investable wealth ，理解到这里就可以啦。

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 given level of risk. 

从组合理论的角度来看，符合这一标准的group在给定风险程度上收益最大。

 Furthermore, the inclusion of more markets expands the opportunities for applying active investment strategies, assuming the decision to invest actively has been made.

进一步，假设策略是主动投资的话，囊括更多的市场使得主动投资策略的机会更多。

However, such factors as regulatory restrictions on investments and government-imposed limitations on investment by foreigners may limit the asset classes an investor can invest in.

但是由于有各种监管限制，外国人可能会被限制投资本国资产。
