E(ri) = rf + (E(rm) rf) OiM OM Here is the CAPM and defines the expected return of an asset , the expected return of asset is E(ri), a function of the risk-free rate, rf, the expected return of market portfolio, E(rm), and have ratio OM = 72M Bi ( O im= the covariance of returns of the asset with the market portfolio ; oM = the variance of returns of the market portfolio) Show that the CAPM Bi is linearly additive. Present all the calculations analytically and explain every step.
