问题如下：
The price of a stock at t = 0 is $208.25 and at t = 1 is $186.75. The continuously compounded rate of return for the stock from t = 0 to t = 1 is closest to:
选项：
A.–10.90%.
B.–10.32%.
C.11.51%.
解释：
A is correct.
The continuously compounded return from t = 0 to t = 1 is r0,1 = ln(S1/S0) = ln (186.75/208.25) = –0.10897 = –10.90%.
老师您好，一看到这道题不知道如何下手，看了一下其他老师的回复，所以只要看到连续复利就要用对数吗，还有就是想问下是有一个固定的公式吗直接套入吗？谢谢
