问题如下:

Before the meeting ends, Swanson mentions that Americana is launching a new market-neutral fund. This fund will take full advantage of the stock-picking expertise of Americana's research team by expressing negative views through short positions. Swanson's comments to Rizzitano on this topic are captured in Statement 1.

Statement 1: I suggest taking $5 million of the $25 million that the BTU endowment has invested in the Legends Fund and investing the proceeds in this new market-neutral fund. Doing so would allow the BTU endowment to reduce its total equity portfolio market risk (i.e., beta), increase the portfolio's diversification across other non-market risk factors and reduce the portfolio's tracking error.

Rizzitano tells Swanson that he will consider the suggestion.

State whether Swanson's justification in Statement 1 is correct. Explain your reason briefly.

解释:

Answer:

Adding shorts to a portfolio may amplify, rather than reduce, the portfolio's tracking error(i.e., active risk) by increasing the portfolio's active share. Therefore, Swanson's justification for adding the market-neutral fund to the BTU endowment is incorrect.

Investing in the new market-neutral fund would indeed reduce the BTU endowment's overall market risk (beta) since market-neutral funds aim to neutralize beta.

However, the claim that this would increase diversification across non-market risk factors is not accurate. Beta is a measure of market risk, not a non-market risk factor.

Additionally, reducing beta does not directly imply a reduction in tracking error, which is influenced by the portfolio's alignment with its benchmark.

嗨,努力学习的PZer你好:


同学的回答是可以的。可以这么回答。

也可以通过这个问题了解一下三级简单题的解答技巧。


三级题目简单一般有三个要点:结论、证据、解释。

一般每个得分部分占比这题总分的1/3。

写全了才能拿全分。


以本题为例:


结论(直接选答案,对还是错)

在正常的多头portfolio里增加一个market - neutral,会增加active risk。

Statement 1 is incorrect。


解释(原版书知识点)

active risk有两个来源:一是correlation,二是active share。

correlation减少,active risk增加。

active share增加,active risk增加

证据(结合题目信息)

1)加入market - neutral后,由于market - neutral与benchmark相关性低,增加active risk。

2)加入market - neutral后,由于market中有空头,会增加active share,增加active risk。
