问题如下:

Which of the following individual behavioral biases is most strongly associated with market bubbles?

选项:

A.

Overconfidence

B.

Representativeness

C.

Framing

解释:

A is correct.

The overconfidence and excessive trading that contribute to a bubble are linked to self-attribution bias, a form overconfidence. In a rising market, sales of stocks from a portfolio will typically be profitable, even if winners are being sold too soon, and FMPs will attribute profits and strong performance to their investment acumen and subsequently underestimate risks.

嗨,从没放弃的小努力你好:


represetativeness bias代表性偏差是指人们会基于自己过去的经验形成一个个思维模板,然后新的信息也去套旧的模板。而市场泡沫中,投资者往往表现出过度自信,认为盈利表现归功于他们自身的能力,过度交易然后低估风险。represetativeness bias跟bubbles关系不大。

虽然现在很辛苦,但努力过的感觉真的很好,加油!
