不管在什么地方提到risk都是volatility吗

NO.PZ2023010903000005

问题如下:

Hans Smith, an Albright portfolio manager, makes the following notes after examining these funds:

Note 4 Of the four funds, the Elmer Fund is most likely to appeal to investors who want to minimize fees and believe that the market is efficient.

Note 5 Adding investment-grade bonds to the Elmer Fund will decrease the portfolio’s short-term risk.

Which of the notes regarding the Elmer Fund is correct?

选项:

A.

Only Note 4

B.

Only Note 5

C.

Both Note 4 and Note 5

解释:

For passively managed portfolios, management fees are typically low because of lower direct costs of research and portfolio management relative to actively managed portfolios. Therefore, Note 4 is correct.

Note 5 is incorrect because the predictability of correlations is uncertain.

会因为这个是passive的fund所以risk就是tracking error吗

嗨,从没放弃的小努力你好:


Hello,亲爱的同学~


不管在什么地方提到risk都是volatility吗

并不是risk都是volatility。risk有各种类型。

实际上volatility也有各种类型。

有的题目里,volatility表示为方差,有的题目里表示为标准差。

有的题目会表示为其他形式的波动率。


会因为这个是passive的fund所以risk就是tracking error吗

例如本题是passive 的fund,所以risk更多考虑tracking error。

虽然现在很辛苦,但努力过的感觉真的很好,加油!
