Page 1 of 9
Background and Introduction
This summary provides a brief overview of Capital Asset Pricing Model (CAPM) as an alternative method for estimating expected returns. This paper also discusses the positive and negative effects of CAPM along with the risks of Beta and why this model has its share of drawbacks and critics in the marketplace. The first section will cover the basics of CAPM including its flaws and rewards. Next, the risks of beta and the strengths and weaknesses are discussed in conjunction with its relevance to CAPM and why it’s important to investors who are willing to take greater risks. Finally, an application is provided to show how beta affects CAPM from a financial manager’s perspective.

There is only one beta used in the CAPM model and it serves as the full measurement of systematic risk and future cash flows. CAPM is not a perfect science nor do all investors agree on measuring the beta (risk) of an asset.
