Capital asset pricing model and arbitrage pricing theory: a comparative analysis by yohanna g jugu and yunisa simon amodu department of accounting. In finance, the capital asset pricing model (capm) is a model used to determine a theoretically appropriate required rate of return of an asset, to make decisions about adding assets to a well-diversified portfolio. The capital asset pricing model (capm) is a theory of the relationship between the risk of a security or a portfolio of securities and the expected rate of return that is commensurate with that risk the theory is based on the assumption that security markets are efficient and dominated by risk averse investors.

The capital asset pricing model (capm) is an idealized portrayal of how financial markets price securities and thereby determine expected returns on capital investments the model provides a methodology for quantifying risk and translating that risk into estimates of expected return on equity.

- Capital asset pricing model is empirically un-testable because the market portfolio on which it is based is unobservable whenever we implement capm test that use market proxies, we will have to face this criticism.
