Resumen:
This methodological paper presents an alternative framework for studying the cross-section of returns through factor construction. We seek a factor definition that is mathematically consistent and establishes an assumptionfree architecture. The new framework is not only highly versatile and enables immediate economic analysis, but also overcomes well-known issues with discretionary choices reported in the literature. Graded factors, unlike their classical counterparts, offer intensity metrics and can be standardised for comparison across factors. Their additive nature enables factor decomposition and concurrent multi-factor analysis, unlocking opportunities for cross-sectional and time-series causal studies. We illustrate the properties of graded factors by applying the new framework to examine three classical problems in factor investing: the theoretical consistency of excess returns as recurring payoffs for risk, the interaction of size and value, and the effect of sector composition as an omitted variable. We also explore the interactions among the size, value, and greenness factors. Our work contributes to finance theory by offering a more objective, systematic approach to factor returns, with substantial implications for investment practices and firm valuation.
