assets‚ there exists a portfolio on the lower part of the portfolio frontier‚ rzp ‚ which is uncorrelated with it. Its β defined as Cov(rp ‚ rzp )/V ar(rp ) is therefore 0. That’s why the model is called the zero-beta CAPM. Let γ = E(rzp )‚ then the theory says that E(Rt − γ) = βE(Rpt − γ) We can estimate the model asset by asset using nonlinear least square (NLS). The formula must be in the form r = γ(1 − β) + βRm . Let g and b be γ and β‚ we can compare the estimates of γ as follows: > > + + + + +

the only unknown: d. The SML is plotted below. Data on the risk-free security (bRF = 0‚ kRF = 8.6%) and Security X (bX = 0.56‚ = 10.6%) provide the two points through which the SML can be drawn. kM pro¬vides a third point. e. In theory‚ you would be indifferent between the two stocks. Since they have the same beta‚ their relevant risks are identical‚ and in equilibrium they should provide the same returns. The two stocks would be represented by a single point on the SML. Stock
