这里的behavioral bias是什么

问题如下：

Company A released its annual report to the public recently and its share price reacts gradually to it. With respect to efficient markets, which of the following statements about the market is correct?

选项：

The market is subject to behavioral biases.

The market is semi-strong-form efficient.

The market received additional information about the company.

解释：

C is correct.

The information from the annual report is already reflected in the stock prices if the markets are efficient. So the gradual changes of the stock prices are not to the releasing of annual report but to additional information.

考点：Efficient Capital Market And Its Forms

这里的“gradually”很重要，说明信息不是立即反应至价格的，因此市场不是有效的。价格在慢慢变化就说明还有其他信息。

这里的behavioral bias是什么？A选项是什么意思呢？

嗨，努力学习的PZer你好：

同学你好，A选项的意思就是说题干说的现象说明市场存在行为金融中说的行为偏差的现象

这道题目的正确答案是C，A是错误的，意思就是题干说的现象是不存在behavioral bias的哦
