老师好, 考试如果碰到这种题目,可不可以就用方法一 来做,就是直接Dp = 1/3 * 5 + 1/3*10 + 1/3*30 因为题目有提到the portfolil has equal weightings in each key rate duration, 是否不提也可以默认是equal weighted? 然后做出delta p / p = -15 delta Level- 3 delta Steepness -1.166667delta curvature? 然后因为LEVEL 前系数-15,最大,再加loss from changes in steepness 会导致P上去,于是带入这公式里,所以most likely be a loss in value from changes in level and a loss from changes in steepness 选C, 对吗? 谢谢。
