这个不应该是consrtvatism bias嘛

  1. CFA I
  2. Portfolio

NO.PZ2018101901000021

问题如下：

The halo effect, which may be evident in FMP’s assessments of a company with a history of high revenue growth, is a form of which behavioral bias?

选项：

A.

Endowment

B.

Representativeness

C.

Regret aversion

解释：

B is correct.

Representativeness refers to the tendency to adopt a view or forecast based on individual information or a small sample, as well to use simple classifications. The halo effect is an example of representativeness, because FMPs extend an overall favorable evaluation to an investment (e.g., a “good company”) based on one or few characteristics (e.g., a “visionary CEO”).

这个分不清。难道不是conservatism bias?

嗨，努力学习的PZer你好：


光环效应就是自带滤镜，比如一家具有良好成长记录的公司，我们通常会给他一个超过他价值的更高的预期。或者解释中说的，一家公司有一个有远见得CEO，我们就基于这一个特点就觉得这家公司总体情况都很好，这就是典型的代表性偏差，基于过去得一个简单片面的观点或主观印象做判断。

保守偏差跟这个没有关系，它指的是维持原先的观点不愿意去更新信息。
