问题如下:

In her market research, the manager learns that ASX 3-year and 10-year Treasury bond futures are the most liquid products for investors trading and hedging medium- to long-term Australian dollar (AUD) interest rates.

Although neither contract matches the exact characteristics of the cash bonds of her choice, which of the following additions to a barbell portfolio best positions her to gain under a bull flattening scenario?

选项:

A.

Purchase a 3-year Treasury bond future matching the money duration of the short-term (2-year) position.

B.

Sell a 3-year Treasury bond future matching the money duration of the short-term bond position.

C.

Purchase a 10-year Treasury bond future matching the money duration of the long-term bond position.

解释:

C is correct.

A bull flattening is a decrease in the yield spread between long and short-term maturities driven by lower long-term yields-to-maturity.

Both A and B involve changes in portfolio exposure to short-term rates, while C increases the portfolio exposure to long-term rates to benefit from a fall in long-term yields-to-maturity.

这题我做对了,但是在b和c里纠结了一下,最后觉得c更合适(其实我不明白为什么C更合适)

嗨,努力学习的PZer你好:


barbell由短期和长期组成,虽然短期和长期都有久期,但相对于长期,短期的久期更小,甚至可以忽略

所以,收益最大的策略肯定是对长期的money duration

C就是用10年future改变barbell中的长期money duration

B是用3年期future改变barbell中的短期money duration.

虽然B也可以盈利,但肯定没有C的盈利多。
