老師您好！ reading24課后題第12題提到loses curvature，我畫了圖應(yīng)該是指圖一、圖二，但是我想問的是：圖三、圖四是不是也是一種可能性呢？這樣就增加了curvature呀？ 謝謝老師！ C is correct. Hirji proposes an extreme bullet portfolio focusing on the middle of the yield curve. If the forecast is correct and the yield curve loses curvature, the rates at either end of the curve will rise or the intermediate yields will drop. As a result, bonds at the ends of the yield curve will lose value or the intermediate bonds will increase in value. In either case, the bullet portfolio will outperform relative to a more diverse maturity index portfolio like the benchmark.

老師您好！ Reading 24課后題第11題的答案顯示 money duration=market value *pvbp： The C$150 million long-term bonds have a money duration of C$150 × 1,960 = C$294,000 (Institute 225) Institute, CFA. 2019 CFA Program Curriculum Level III Volume 4. CFA Institute, 5/2018. VitalBook file. 這與課本上的定義有出入吧？ Money duration is market value multiplied by modified duration, divided by 100.13 PVBP is market value multiplied by modified duration, divided by 10,000.
