问题如下：
All of the following are reasons that an apparent deviation from the efficient market hypothesis might not be anomalous except:
选项：
A.The abnormal returns represent compensation for exposure to risk.
Changing the asset pricing model makes the deviation to disappear.
The deviation is well known or documented.
解释：
C is correct.
Bubbles and crashes are well-known and well-documented phenomena yet represent market anomalies.
看不懂这个题目和选项说的啥，能解释一下吗？谢谢！

嗨，爱思考的PZer你好：
这道题题干问的是，以下哪个不是偏离有效市场假说但不是异常现象的解释。
A异常收益代表了对风险敞口的补偿。所谓的偏离可能来自于你用的资产定价模型不同。因此他不是异常现象。
B改变资产定价模型可以使这种偏离消失。跟A是一个意思，说明不是异常现象。
C选项偏离是众所周知并被记录的。这个不一定的，例如解释里面说的，bubbles和crashes是一种异常现象，他更多时候是用行为金融去解释。所以选择C。
----------------------------------------------虽然现在很辛苦，但努力过的感觉真的很好，加油！
