NO.PZ201710200200000104 问题如下 4. Raye believes the previous aiser’s asset class specifications for equity anrivatives are inappropriate given that, for purposes of asset allocation, asset classes shoulbe: A.versifying. B.mutually exclusive. C.relatively homogeneous. A is correct. For risk control purposes, asset class shoulversifying anshoulnot have extremely high expectecorrelations with other classes. Because the returns to the equity anthe rivatives asset classes are notebeing highly correlate inclusion of both asset classes will result in plication of risk exposures. Inclung both asset classes is not versifying to the asset allocation.考点asset class的分类标准解析versifying指的是资产类型之间的相关性不能过高，正文部分提到asset class returns on equity anrivatives are highly correlate因此资产类型的分类违反了versifying。易错点分析本题常见错误选B。一是对asset class的分类标准理解不够准确，二是认为大盘国外股和美国股票之间可能存在重合。事实上，大盘国外股是衍生品的标的物，而非投资产品本身，所以没有违反mutually exclusive。 易错点分析本题常见错误选B。一是对asset class的分类标准理解不够准确，二是认为大盘国外股和美国股票之间可能存在重合。事实上，大盘国外股是衍生品的标的物，而非投资产品本身，所以没有违反mutually exclusive。我理解大盘国外股和美国股票之间并不是重合的，所以没有违反mutually exclusive。答案中“大盘国外股是衍生品的标的物，而非投资产品本身，所以没有违反mutually exclusive” 这句话应该怎么理解？逻辑关系是怎样的？谢谢！

mutually exclusive. relatively homogeneous. A is correct. For risk control purposes, asset class shoulversifying anshoulnot have extremely high expectecorrelations with other classes.
