资本资产定价模型(CAPM)一直是一个备受关注的问题。对它的分析与研究能促使我们完善此模型。本文探讨资本资产定价模型以及其优缺点。CAPM模型的优点在于:模型简单明了,客观的阐述了风险和收益的关系,即高风险对应高收益。与此同时CAPM模型也存在着不足:模型假设过于苛刻脱离实际,贝塔参数难测量。
Capital Asset Pricing Model (CAPM) has always been a concern. Its analysis and research can prompt us to perfect this model. This article explores the capital asset pricing model and its advantages and disadvantages. The advantages of the CAPM model are as follows: The model is simple and clear, objectively illustrates the relationship between risk and return, that is, high risk corresponds to high yield. At the same time, there are some shortcomings of the CAPM model: model hypothesis is too harsh from reality, beta parameters difficult to measure.
