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?
