我觉得这题难点在于 interest only strip 和 principle only strip 到底是一个什么东西,这个之前讲课的老师都没有讲过,看了您前面几个回复,还是不是特别懂,距离 interest only strip,首先这个strip的含义是什么?假如利率上升,然后呢?债券的价格会上升?为什么?
查看试题 已回答A hedge fund manager wants to change her interest rate exposure by investing in fixed-income securities with negative duration. Which of the following securities should she buy? 1.decrease in value as interest rates fall and increase in value as interest rates rise.?我记得当时讲的是D和R同向 和Y反向,为什么这里是R升,value也升? 2.Zero coupon bonds with long maturity will increase in value as interest rates fall, so calls on these bonds will increase in value as rates fall ,but puts on these bonds will decrease in value。这句不明白,为什么R降,call值升,而put值是降? 3.Interest-only strips from long maturity conforming mortgages will decrease in value as interest rates fall, so puts on them will increase in value。 为什么IO的duration是小于0?且是R降,value降? 4.principal strips on these same mortgages will increase in value, so calls on them will also increase in value. 为什么PRN strips的D是大于0?R降,value升? 谢谢
