问题如下:

In regard to Shaw’s comments about Fund A and Fund B, the one that is most accurate concerns:

选项:

A.Fund A’s fees.

B.Fund A’s dispersion.

C.Fund B’s sector bets.

解释:

Solution

B is correct. Shaw’s comment about Fund A’s dispersion is correct. With a higher active risk (tracking error), Fund A has a greater likelihood of having results dispersed more broadly (both positive and negative) around benchmark results than Fund B has. Investors are more likely to be willing to pay higher fees for higher Active Share as an indicator of greater active management, but Active Share is identical for Fund A and Fund B. Sector bets are likely to affect active risk; therefore, Fund A is more likely to be using sector bets, not Fund B.

A is incorrect. Investors are more likely to be willing to pay higher fees for higher Active Share as an indicator of greater active management, but Active Share is identical for Fund A and Fund B.

C is incorrect. Sector bets are likely to affect active risk; therefore, it is Fund A that is more likely to be using sector bets, not Fund B.

请老师解释一下C选项,正是因为B做了factor bet,所以它的active risk才低呀?

嗨,从没放弃的小努力你好:


请老师解释一下C选项,正是因为B做了factor bet,所以它的active risk才低呀?


Hello ,亲爱的同学~


这里要从active risk来源这个知识点作分析。

我们知道,Active risk 来自于,相关性因素(factor差异引起),持股因素(即active share因素)。


结合本题信息点:

A基金与B基金的active share接近,但是A的active risk更高。

既然active share因素一样,那么A基金高的active risk,就来自相关性因素,也就是factor差异。

A基金的factor与benchmark的factor差异大,说明A在factor上择时,因此A是factor bet.

----------------------------------------------
虽然现在很辛苦,但努力过的感觉真的很好,加油!

相关性因素为什么就是factor差异、factor bet?

他说的是sector bet,sector bet 和factor bet是同一个东西?
