The CAPM Formula The CAPM formula is given by:E(ri)=rf+βf(E(rm)−rf)Where: E(ri) is the expected return of the asset or portfolio denoted with i. rf is the risk-free rate of return. βi (beta) is the sensitivity of returns of asset i to the returns from the market and ...
The CAPM formula is: Expected Security Return = Riskless Return + Beta x (Expected Market Risk Premium) or: r = Rf + Beta x (RM - Rf) { Another version of the formula is: r-Rf = Beta x (RM - Rf) } where: - r is the expected return rate on a security; ...
Take the value for expected asset return found in step two and the actual observed return of that asset and solve for alpha using the formula: alpha = return on investment – expected return on investment. An alpha greater than zero means the investment outperformed its expected return. Tip If...
157-159. SFMM Covariance Matrix The SFMM giv se to a returns covariance matrix Σ that has a relatively simple structure for which a formula can be derived for the inverse covariance matrix. Drop the time subscript we have the “cross-section” SFMM , with the same assumptions on the ...

If you believe the EMH then alpha will always be zero or go to zero before you can capitalize on it. The first Hedge founds came up with a clever scheme to avoid this. If you have two stocks, one you think is going to go up (positive alpha) and another that you think will go do...
