同學你好,
要實現(xiàn)zero vega的話,那么這個期權肯定是deep in the money或者deep out of the money,因為期權在deep in the money或者deep out of the money的狀態(tài)下vega才是趨近于0的,所以A和C都錯了,
再看D和B,看漲期權的價值和利率是正相關的,所以買入看漲期權能夠在利率上漲的時候獲益,符合題意,而看跌期權和利率是反向關系,綜合起來,這道題選B呀
increase in rate will cause larger increases for in the money calls,but larger decreases for in the money puts,這個指的是利率的上漲和下跌,此時,in the money calls價值上漲,in the money puts價值下跌
