各位好
最近在研究利率商品的券商报告
其中在trade volatility的组合不太理解
原文如下
1. Selling ATM 1y*10y payers against 1y*2y and 1y*30y payers, given the relati
ve richness of 1y*10y vols.
2. Recommend 3m*5y 1x2 receiver spreads as a way to benefit from low realized
vol, rich receivers, and the low probability of a large rally.
3. Recommend a 3m*5y-3m*30y ATM+25 bear-steepener to benefit from a large long
-end driven sell-off.
3可以理解但不知道为何要+25
1跟2不太懂这些组合怎么利用到波动率多寡
烦请高手解惑
或是有任何关于swaption strategy的资料
非常感谢!
