问题如下：
2. In presenting Investment 1, using Shire Gate Advisers’ interest rate outlook, Smith could show that riding the yield curve provides a total return that is most likely:
选项：
A.lower than the return on a maturity-matching strategy.
B.equal to the return on a maturity-matching strategy.
C.higher than the return on a maturity-matching strategy.
解释：
C is correct.
When the spot curve is upward sloping and its level and shape are expected to remain constant over an investment horizon (Shire Gate Advisers’ view), buying bonds with a maturity longer than the investment horizon (i.e., riding the yield curve) will provide a total return greater than the return on a maturity-matching strategy.
我觉得这道题和上课讲的例题原理是不一样的。
上课讲的题，是把 A.投资期 5 年，持有 5 年，和 B. 投资期 30 年，持有 5 年对比，这样riding the yield curve 就有更多收益
这道题是，把 A.投资期 2 年，持有 2 年，和 B. 投资期 2 年，持有 1 年对比.投资期其实是一样长的，根据无套利原理，其实这种情况下 riding the yield curve 和 matching-maturity 收益应该是一样的。
所以这道题应该选 B 不是吗
