问题如下：
The stocks of AAA company have a changing closing price over the last 3 month:
From May to July, the continuously compounded return of AAA company's stocks is:
选项：
A.
18.61%
B.
17.34%
C.
16.89%
解释：
A is correct. Based on definition, for a certain period, the continuously compounded return = the natural log of the period’s change. So we can calculate 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 compounding rate翻译成中文是求什么？
