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%
根据公式,结果应除以2,为什么结果是18.61%,而不是为18.61%/2 吗?
