问题如下图:

问 naive diversification 与 conditional naive diversification,有什么区别?

1 个答案

企鹅_品职助教 · 2020年02月04日

嗨,从没放弃的小努力你好:


正常的1/n naive diversification指的是在所有available funds中等分。

conditional 1/n指的是,在所有可能的funds中选3-5个,在这3-5个funds中等分。

这道题中Calderon先选择了四个highest performing funds,然后在这这个基金中等分投资,所以符合conditional 1/n的策略。

-------------------------------------------------------

conditional 1/n 策略是作为正常的1/n的策略的补充提出来的,所以有时候这两个不会单独区分。

比如题目中说,一个人选了三个基金,在这三个基金中等分。他的行为其实是属于conditional 1/n, 但是如果选项中只有naive diversification的话也要选。


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