我在做NOTES的模拟题(V1,P245)时,遇到下面这句话,是答案里面的解释,可我总是想不明白,求教各位牛人,谢谢
as long as rates do not fall enough to stimulate refinancing, a small drop in treasury rate combined with increased volatility will provide positive outcome for holders of MBS
这句话正好答我刚才的问题。。。汗。。。
谢谢~!
多问一句。。。为什么这个时候会正回报?
MBS不是writing call吗?Volatility增加为什么不是增加call option value从而进一步降低MBS价格?
as long as rates do not fall enough to stimulate refinancing
这个才是重点吧。。因为还没有下跌到Call起作用,Call option在这里没有价值。Volatility增加只会造成Bond value未来更加不确定,导致价格下降
