三个选项都帮忙解读一下,谢谢

NO.PZ2019012201000063

问题如下:

Which fund in Exhibit 1 most likely follows a bottom-up approach?

选项:

A.

Fund 1

B.

Fund 2

C.

Fund 3

解释:

Bottom-up managers evaluate the risk and return characteristics of individual securities and build portfolios based on stock-specific forecasts; Fund 3 follows this exact approach. Example views of bottom-up managers include expecting one auto company to outperform another, expecting a pharmaceutical company to outperform an auto company, and expecting a technology company to outperform a pharmaceutical company. Both bottom-up and top-down managers can be either diversified or concentrated in terms of securities.

嗨,爱思考的PZer你好:


Fund1是捕捉国家、资产类别、行业的因子收益的。并没提到个股,因此不是bottom up



fund 2 虽然关注个股成长,但是它不属于bottom up。


fund 2里,基金经理摆出了一个观点,然后按照这个观点来配置股票,所有的股票配置,都不是基于股票自身微观特征,而只是为这个观点服务。这里隐含了一个逻辑,股票不是基于自身,而是基于观点,而bottom up 必须基于股票自身,而不能基于其他因素,这就否定掉了bottom up,用排除法就只有Top down。


具体可以原版书黄色部分,对风格有先验的观点,是top down。虽然本题没有阐述,基金经理主观认为,growth风格要比value风格好,是基于什么原因,但是结合原版书内容,原版书认为,会产生这种先验性风格判断观点的因素,这可能是基于宏观因素,比如油价上涨,现金跑赢股票,或者基于现金与股票的资产配置。


认为某个风格(例如growth)强于另一个风格(例如value),依然是赌风格,属于top down。这个知识点,就用这道题来补充吧。


Fund 3建立一个分散化组合,并根据个股的特征制定投资策略。这就是bottom up。
