问题如下:
A Dutch investor considering a 5-year EUR government bond purchase expects yields-to-maturity to decline by 25 bps in the next six months. Which of the following statements about the rolldown return is correct?
选项:
A.The rolldown return equals the difference between the price of the 5-year bond and that of a 4.5-year bond at the lower yield-to-maturity
B.The rolldown return consists of the 5-year bond’s basis point value multiplied by the expected 25 bp yield-to-maturity change over the next six months.
The rolldown return will be negative if the 5-year bond has a zero coupon and is trading at a premium.
解释:
C is correct.
Rolldown return is the difference between the price of the 5-year bond
and that of a 4.5-year bond at the same yield-to-maturity.
A 5-year zero-coupon bond trading at a premium has a negative
yield. As the price “pulls to par” over time, the premium amortization will be
a loss to the investor.
A reflects the full price appreciation since it is calculated using the lower yield-to-maturity, while B equals E (Δ Price due to investor’s view of benchmark yield).
如果用YTM的方式计算rollodown return,那么用的是same YTM,就是这个5年期债券0时刻par value折现用的折现率,而不是之后的YTM?(比如:之后的YTM降低了0.5%)
