The work of Treynor and Mazuy (Harvard Business Review 44:131-136, 1966) spawned an extensive literature on returns-based measurement of portfolio performance which distinguishes between a manager’s ability to act on information specific to an individual asset (asset selection) and ability to forecast systematic risk premiums and adjust portfolio exposures accordingly (market, or factor, timing). In a world in which both dynamic trading strategies and derivative securities provide payoffs which are nonlinear in factor returns, obtaining a clear separation between asset selection and market timing is difficult. Additionally, predictability of risk premiums causes a confounding of timing based on public information versus true skill. However, disaggregating the measurement of the components allows us to obtain more accurate measures of the quantity of interest, total portfolio performance.
