问题如下：
The weekly closing prices of Mordice Corporation shares are as follows:
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%
老师，没看懂这个题的意思，能讲一下吗？

同学你好，
这道题涉及lognormal distribution下讲的一个考点：continuously compounded return （连续复利下的收益率）=Ln（S1/S0）
对于本题而言，求的是“ the period August 1 to August 15 ”的连续收益率，所以S1为8.15价格，即120，S0为8.1价格，即112.
所以连续收益率=Ln（120/112），即可得出A选项。

请问这个是年化收益吗？这道题要求的是年化收益吗？

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% 这个公式可以一下背后的逻辑吗

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% 可以理解连续复利，但是15天的连续在计算中怎么提现的呢，假如题里问8天时的连续复利收益，除了把120替换成160，还有其他计算区别吗

NO.PZ2017092702000093 7.14% 8.95% A is correct. The continuously compounreturn of asset over a periois equto the naturlog of perios 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% 能一下为什么用ln计算么，没太懂
NO.PZ2017092702000093 为什么不能直接用（1+r/m）^m=FV/PV 这样来算呢，这样算出来是答案B。
