问题如下：
A financial analyst is examining whether a two years price of stock A, last year is $45, this year is 77, what is most likely correct?
选项：
A. the continuously compounded rate of return is 53.71%
B. the continuously compounded rate of return is 71.11%
C. the continuously compounded rate of return is 43.32%
解释：
A is correct. the continuously compounded rate of return is ln(77/45)=0.5371.
为什么这道题与lognormal有关系呢 用到了哪个性质呢NO.PZ2018062016000104问题如下 A financianalyst is examing the change of the priof stolast yeis $45, this yeis 77, whis most likely correct? A.the continuously compounrate of return is 53.71%B.the continuously compounrate of return is 71.11%C.the continuously compounrate of return is 43.32%A is correct. the continuously compounrate of return is ln(77/45)=0.5371.如果连续复利求收益率，只求3个月的连续复利，是乘以e的四分之三r次方吗

NO.PZ2018062016000104 能讲一下Ln(77/45)、(77-45)/45分别适用的情况吗？还有别的收益率算法吗？
