解释:
老师能解释下这道题吗?这道题应该只涉及duration effect吧?为什么选a呢
NO.PZ2016031002000067 问题如下 Ann wants to measure the relationship between bonprianyielfor option-free baseon the ration. When the yielcreases, the estimation of priincrement will be: A.smaller. B.larger. C.either smaller or larger. A is correct.The relationship between bonprianyielfor option-free bonis convex while ration is a linemeasurement. So the estimation of priincrease just baseon ration will smaller ththe actupriincrease if the yielcreases.考点ration convexity解析如果单考虑ration的影响,忽略了convexity的影响,那只是线性的影响。当利率下降时,债券价格的上涨幅度就没有那么多。故A正确。如果把ration和convexity都考虑在内,存在涨多跌少,那么债券上涨的幅度相比只考虑ration更多。 这题目问的是啥意思? 是不是应该问的更清楚些? 请问老师

NO.PZ2016031002000067 我是想问如果只考虑ration的话,是不是yiel升和下降相同的base-point,price上升和下降都是同等的,相同的!(就不是涨多跌少了吧,就是都一样了吧?)
