同学,你好。The positive butterfly, which indicates a decrease in the butterfly spread due to an expected rise in short- and long-term yields-to- maturity combined with a lower medium-term yield-to- maturity.
The negative butterfly, which indicates an increase in the butterfly spread.
Butterfly spread=−YS+2×YM−YL
case 3,第5题说,观点是发生negative butterfly,也就是说butterfly spread是会上升。也就是说预估中期利率上升,而预计短期和长期利率会下降。所以我们应该long Barbell,short Bullet。
