问题如下:

Danny Moynahan, CFA, is a fixed-income portfolio manager at Reagan Investment Advisory (Reagan). He agrees with his wife, a professor of investments class, to talk to her class about managing fixed-income portfolios. He plans to put together six pages for his discussion.

Tom Gayle, Moynahan’s superior, stops by Moynahan’s office. Moynahan shares his presentation with Gayle, who suggests that page 4 include a discussion about expected returns. They decide to outline an example of a recent bond trade where they bought a $100 par value bond at a premium. Moynahan presents a decomposition of the bond’s expected returns detailing various components and focuses on roll down return. He adds the following footnote: “The roll down return demonstrates how the price of a bond typically moves closer to par regardless of yield curve changes over the strategy horizon.”

Is the footnote Moynahan includes on page 4 most likely correct?

选项:

A.

Yes.

B.

No, with respect to bond prices.

C.

No, with respect to roll down return.

解释:

C is correct. The footnote Moynahan includes on page 4 is incorrect with respect to roll down return. The roll down return is equal to the bond’s percentage price change assuming an unchanged yield curve over the strategy horizon. The roll down return results from the bond “rolling down” the yield curve as the time to maturity decreases. As time passes, a bond’s price typically moves closer to par.

A is incorrect. Moynahan’s footnote regarding the yield curve is not accurate.

B is incorrect. Moynahan’s footnote with respect to bond prices is accurate.

随着时间的流逝,债券价格是会回归面值的,rolldown return也是随着时间流逝债券价格的变化,那这句话没问题啊

嗨,努力学习的PZer你好:


rolldown return是随着时间的流逝,收益率沿着曲线由远向近rolldown,带来的price return,而不是price向面值靠拢,那是会计记账成本的变化,不是rolldown return。

努力的时光都是限量版,加油!

The roll down return 是yield curve 不变的时候随到期日临近债券价格的变化
