A long criticism on the usefulness of the traditional CAPM model has been raised in the asset pricing literature (Fama and French (2004)). Our paper addresses misspecification issues in multifactor models due to asymmetric diversification effects across firm specific characteristics and proposes a new model that accounts for the diversification intensity of risk premia. Using data from US exchanges we find that strategies on size, value, liquidity and financial distress contain greater risk than what is actually dictated by conventional self-financing long-short trading strategies. Finally, it is found that the magnitude of risk premia are associated with low intra-securities’ correlations.
