Measure
Factor exposure
Definition
How much of a fund's return is explained by systematic factors rather than by stock picking.
Formula
r_p − r_f = α + Σ βₖ · Fₖ + ε
How to read it
Regressing a fund on market, size, value, profitability, investment and momentum factors usually explains the great majority of its variance.
What it does not tell you
Loadings are estimated over a window and drift. A high loading is a description of the past, not a commitment by the manager, and the residual α is whatever the chosen factor set failed to capture — including factors nobody put in the regression.
