问题如下：
Wang is a fixed-income analyst in a wealth management firm. He expects the yield curve will remain stable over the next 12 months. Suppose the investment horizon is 1 year and he wants to use the following components to calculate the return of the buy-and hold strategy. The following table shows the relevant information:
According to the information above, what is the total expected-return for the buy-and-hold strategy?
选项：
A.2.02%
B.2.79%
C.2.88%
解释：
B is correct
考点：利用收益率分解公式各Components计算Total expected return.
解析：由公式：
Total expected return = Yield income + Rolldown return + E(Currency gains or loses)
请问这道题目是不是因为说了yield curve 是stable 的，所以不用考虑第三项E(△y)?不存在由于收益率曲线变动带来的影响
