NO.PZ2018062016000093问题如下 The stocks of Acompany have a changing closing priover the last 3 month:From Mto July, the continuously compounreturn of Acompany's stocks is:A.18.61%B.17.34%C.16.89%A is correct. Baseon finition, for a certain perio the continuously compounreturn = the naturlog of the perios change. So we ccalculate that: ln(159/132) = 18.61%1.ppt上的s1/s0=eʳ，但是这里是只有三个月而不是一年，为什么eʳ不用总体再1/4次方（即三个月），r是年名义利率（投资率）2.题目所求的continuously compounng rate翻译成中文是求什么？

Baseon finition, for a certain perio the continuously compounreturn = the naturlog of the perios change. So we ccalculate that: ln(159/132) = 18.61%我用期初132及期末159，计算出r为20.4545%，然后用e^r-1来计算连续复利的利率，最终得不到答案，我是把哪个定义搞错了吗？
