问题如下:

Edgarton evaluates the Fund’s positions from Exhibit 1 along with two of his pro forma portfolios, which are summarized in Exhibit 2:

Edgarton expects a steepening yield curve, with short-term yields rising by 1.00% and long-term yields rising by more than 1.00%.

Based on Exhibits 1 and 2, which of the following portfolios is most likely to have the best performance given Edgarton’s yield curve expectations?

选项:

A.

Current Portfolio

B.

Pro Forma Portfolio 1

C.

Pro Forma Portfolio 2

解释:

C is correct.

Given Edgarton’s expectation for a steepening yield curve, the best strategy is to shorten the portfolio duration by more heavily weighting shorter maturities. Pro Forma Portfolio 2 shows greater partial duration in the 1- and 3-year maturities relative to the current portfolio and the least combined exposure in the 10- and 30-year maturities of the three portfolios. The predicted change is calculated as follows:

Predicted change = Portfolio par amount × partial PVBP × (-curve shift in bps)/100

老师请问这个知识点在讲义那个地方呢

嗨,努力学习的PZer你好:


同学你好,这个知识点考察的是基于yield curve的主动管理策略。收益率曲线变化有stable、parral shift、non parrel shift等不同情况,我们有不同的主动出击方式,通过构建不同的portfolio来获得excess return。本题考察的是non parrel shift下的策略,一般情况下可以构建barbell、bullet、condor或者butterfly portfolio来定性判断portfolio的表现。

但本题current portfolio与portfolio 1、portfolio 2的现金流特征没有太明显的区别,因此无法定性判断三个portfolio是bullet还是barbell。所以,我们要具体计算一下,用到的公式是△P=∑PVBP*△y,计算结果是△current portfolio=-0.1169%、△portfolio1=-0.1198%、△portfolio2=-0.114465%。所以,portfolio2是表现最好的。

虽然现在很辛苦,但努力过的感觉真的很好,加油!
