Asset Pricing Model (CAPM)
•Expected
Return on the Market - The expected market return is an important concept in
risk management, because it is used to determine the market risk premium. The
market risk premium, in turn, is part of the capital asset pricing model,
(CAPM) formula. This formula is used by investors, brokers and financial
managers to estimate the reasonable expected rate of return on a given
investment.

•The
Security Market Line (SML) is the graphical depiction of the capital asset
pricing model (CAPM)
•The
expected return on a security with a beta of 0 is equal to the risk-free rate.
•The
expected return on a security with a beta of 1 is equal to the expected return
on the market.

CAPM
Example
•The
shares of Aardvark Enterprises have a beta of 0.7. The risk-free rate is
assumed 3%, and the difference between expected return on the market and the
risk-free rate is assumed to be 8.0%. What are the expected return on the two
securities?
•
Aardvark expected return:
15.0% = 3% + 1.5 x 8.0%
Zebra expected return:
8.6% = 3% + 0.7 x 8.0%
