为什么home bias不能解释惯性定律啊

  1. CFA I
  2. Portfolio

NO.PZ2018101901000023

问题如下：

Momentum, can be partly explained by the following behavioral biases except:

选项：

A.

availability.

B.

home bias.

C.

regret.

解释：

B is correct.

Home bias refers to FMPs preferentially investing in domestic securities, likely reflecting perceived relative informational advantages, a greater feeling of comfort with the access to company executives that proximity brings (either personal or through a local brokerage), or a psychological desire to invest in a local community. Momentum, on the other hand, has been documented in a range of markets around the world, in a time-dependent manner, and reflects some FMPs’ availability bias, manifested as a belief that stocks will continue to rise because recently they have only risen, as well as regret aversion by those who invest in past winners because they regret not investing in them in the past.

嗨，爱思考的PZer你好：


home bias就是更偏好于自己国家的股票，因为对自己国家更了解，会觉得更容易掌控。这跟惯性定律没有什么关系，惯性定律是说如果一个基金过去表现得一直很好，但他们没有买，他们会后悔当时为什么没有买，而且他们会相信股票会继续上涨，因此，为了避免后悔情绪他们会选择现在买，因此市场就会形成一个短期趋势。
