问一道题:NO.PZ2018070201000111

问题如下:

Which of the following makes the existence of market portfolio in the capital market theory?

选项:

A.

All investors are price takers.

B.

All investors have homogeneous expectations.

C.

All investors have the same, single holding period.

解释:

B is correct.

Homogeneous expectations assumption claims that all investors are rational and would use the same way to analyze securities, meaning that all investors adopt the same probability distributions, the same inputs for future cash flows and would finally reach to the same valuations for the securities. As a consequence, the market portfolio, which is also perceived as the same optimal risky portfolio, is generated.

同学你好,

capital market theory主要是risky asset和risk-free asset相组合的理论,也就是CML相关理论

马科维茨的理论往往被叫做mean-variance theory,这个理论中没有risk-free asset。

资本资产定价模型一般就直接被称为CAPM。

本章主要就是这三个模型/理论
