The Mechanics of the Formula The standard mathematical representation of the CAPM is expressed as: E(Ri) = Rf + βi (E(Rm) – Rf). The accuracy of the model hinges heavily on the precision of its inputs, particularly the beta coefficient and the future market risk premium, both of which are inherently uncertain and subject to change.
