问题如下：
The rolldown returns over the 1-year investment horizon for the Buy-and-Hold and Yield Curve Rolldown portfolios are closest to:
选项：
A.1.00% for the Buy-and-Hold
portfolio and 3.01% for the Yield Curve Rolldown portfolio, respectively.
0.991% for the Buy-and-Hold portfolio and 3.01% for the Yield Curve Rolldown portfolio, respectively.
0.991% for the Buy-and-Hold portfolio and 2.09% for the Yield Curve Rolldown portfolio, respectively.
解释：
A is correct.
Since both strategies
use zero-coupon bonds, the rolldown return is
calculated from expected bond price changes from “rolling down” the THB
yield curve, which is
assumed to be static.
看到解析答案中提到“Since both strategies use zero-coupon bonds, the rolldown return is calculated from expected bond price changes from “rolling down” the THB yield curve”
为什么要强调zero-coupon bonds? 难道付息债券的rolldown return之计算方法就会不同？
