Where is this manager's return actually coming from — replicable market and sector exposure, or stock selection? Pulled live from the latest 13F and decomposed through the ERM3 cascade. The stock-selection residual — the return remaining after the model's specified market, sector, and subsector exposures — is the component that persists out of sample.

5% of VAUGHAN NELSON INVESTMENT MANAGEMENT, L.P.'s risk is stock-specific over the full monthly history of the reported 13F book — the structural read. Stock selection added 1% of the trailing return (which swings with the window). The rest is buyable market, sector, and style exposure — a descriptive read, not a recommendation.
