这题三个选项都对啊

  1. CFA I
  2. Portfolio

NO.PZ2015121801000111

问题如下：

With respect to capital market theory, which of the following assumptions allows for the existence of the market portfolio? All investors:

选项：

A.

are price takers.

B.

have homogeneous expectations.

C.

plan for the same, single holding period.

解释：

B  is correct.

The homogeneous expectations assumption means that all investors analyze securities in the same way and are rational. That is, they use the same probability distributions, use the same inputs for future cash flows, and arrive at the same valuations. Because their valuation of all assets is identical, they will generate the same optimal risky portfolio, which is the market portfolio.

框架图里assumption这三个选项都有，都是原话。怎么就非得选相同预期呢，解释得太牵强了

嗨，努力学习的PZer你好：


这道题问的是使得market portfolio存在的条件。

要使得market portfolio存在，所有的投资者必须要有相同的预期，这样他们分析问题的方式相同，才能得到同一个optimal risky portfolio，也就是market portfolio。如果预期不同，每个投资者投资的最优风险组合也就不同了，也就不会存在一个统一的市场组合了。


A是对市场的假设，不是对investor的假设。C选项market portfolio的假设并没有假设投资者的投资期，并不要求有single period，只是强调了投资者必须有相同的预期。
