问题如下：
Silvia Abram and Walter Edgarton are analysts with Cefrino Investments, which sponsors the Cefrino Sovereign Bond Fund (the Fund). Abram and Edgarton recently attended an investment committee meeting where interest rate expectations for the next 12 months were discussed. The Fund’s mandate allows its duration to fluctuate ±0.30 per year from the benchmark duration. The Fund’s duration is currently equal to its benchmark. Although the Fund is presently invested entirely in annual coupon sovereign bonds, its investment policy also allows investments in mortgage-backed securities (MBS) and call options on government bond futures. The Fund’s current holdings of on-the-run bonds are presented in Exhibit 1.
Over the next 12 months, Abram expects a stable yield curve; however, Edgarton expects a steepening yield curve, with short-term yields rising by 1.00% and long-term yields rising by more than 1.00%.
Based on Edgarton’s expectation for the yield curve over the next 12 months, the Fund’s return relative to the benchmark would most likely increase by:
选项：
A.riding the yield curve
implementing a barbell structure.
shortening the portfolio duration relative to the benchmark.
解释：
C is correct.
If interest rates rise and the yield curve steepens as Edgarton expects, then shortening the Fund’s duration from a neutral position to one that is shorter than the benchmark will improve the portfolio’s return relative to the benchmark. This duration management strategy will avoid losses from long-term interest rate increases.
是不是应该这样理解这个策略的应用：
riding the yield curve策略使用前提是收益率曲线必须stable；
在stable的基础上，收益率曲线越steepen，策略收益越高？
也就是说，两条stable的曲线之中，更steepen的那条riding the yield curve策略获得更大收益；
而不是说，某曲线本身变得更steepen了，这条曲线上riding the yield curve策略比之前效果更好了，而是这个策略根本就不能用了。
是这么理解么？
