Explain the CAPM model. Choose two firms from that list and discuss whether the betas are what you would expect. Be sure to explain why or why not. Calculate the returns based on the CAPM model. Be sure to state your assumptions.
Capital Asset Pricing Model (CAPM) is used for calculating the expected return of a risky asset.
R = Rf + B * (Rm - Rf)
Where, R = expected return of the risky asset
Rf = risk free rate
B = Beta (systematic risk)
Rm = expected market return
Rm - Rf is also called the equity risk premium.
Firm 1: Apple Inc.
Rf = 2.98% (US 10 year Bond yield)
Beta = 1.14
Equity Risk premium = Rm - Rf = 5.08%(From Aswath Damodaran's website)
Therefore, expected return = 2.98 + 1.14 * 5.08 = 8.77%
Firm 2: Amazon.com, Inc.
Rf = 2.98% (US 10 year Bond yield)
Beta = 1.14
Equity Risk premium = Rm - Rf = 5.08%(From Aswath Damodaran's website)
Therefore, expected return = 2.98 + 1.72 * 5.08 = 11.72%
