The continuously compounded return of Mordice Corporation shares for the period August 1 to August 15 is closest to:
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%
资产在一段时间内的连续复合回报等于期间变化的自然对数。 在本题中:ln(120/112) = 6.90%
能解释一下为什么用ln计算么,没太懂
