Alice in Factorland

Factor tilt strategies have generally produced less alpha in live portfolios compared to theoretical factor long–short paper portfolios and have largely been unsuccessful in replicating smart beta strategies. End-investors, consequently, often reap a much smaller return from factor exposure than they expect. The winning approach to factor investing is buying the losers: Past negative performance appears to be predictive of positive future returns.
