Capital Asset Pricing Model (CAPM)

A mathematical model used to help price a security by determining the relationship between risk and expected return. CAPM is a key element in portfolio theory, in which the expected rate of return (E) on an investment is expressed in terms of the expected rate of return on the market portfolio (rm) and the Beta coefficient ((beta)), E = R + (beta)(rm - R), where R is the risk-free rate of return.
