问题如下：
With respect to efficient markets, a company whose share price reacts gradually to the public release of its annual report most likely indicates that the market where the company trades is:
选项：
A.semi-strong-form efficient.
B.subject to behavioral biases.
C.receiving additional information about the company.
解释：
C is correct.
If markets are efficient, the information from the annual report is reflected in the stock prices; therefore, the gradual changes must be from the release of additional information.
你好，如果市场价格逐步变化，还可以获利的话， 为什么不是weak form inefficient呢？
