选项:
A.6.90%
B.7.14%
C.8.95%
解释:
A is correct.
The continuously compounded return of an asset over a period is equal to the natural log of period’s change. In this case: ln(120/112) = 6.90%
老师,这道题就是一直计息。
在经典题里,那道题是4年,所以是e^(利率*4)
那这道题,他等于是14天,为什么不是112*e^(利率*14/365)=120呢。。。虽然我这边算式里没有一个答案是正确的。
不过我的理解错在哪里了呀?4年乘以4,那么14天,就应该是对应的天数呀?
