问题如下：
Which of the following statements best describes how the expected total return results would change if THB yields were to rise significantly over the investment horizon?
选项：
A.Both the Buy-and-Hold and Yield Curve Rolldown expected portfolio returns
would increase due to higher THB yields.
Both the Buy-and-Hold and Yield Curve Rolldown expected portfolio returns would decrease due to higher THB yields.
The Buy-and-Hold expected portfolio returns would be unchanged and the Yield Curve Rolldown expected portfolio returns would decrease due to the rise in yields.
解释：
C is correct.
In a higher THB yield
scenario in one year, the Yield Curve Rolldown
expected return would fall since a higher THB yield-to-maturity in
one year would reduce
the price at which the investor could sell the 1-year zero in one year.
The Buy-and-Hold portfolio return will be unaffected since the 1-year bond matures at the end of the investment horizon.
老师，题目问total return 怎么变化，不需要考虑currency return 的变化么？
如果说RFX无法判断，那么本题相当于total return只考虑roll down return了？
