Why Do Active Funds Lag Even With Winning Picks?

Aug 7, 2026 · 13m

Summary

Morningstar’s Jeff Patak reveals that a hypothetical "do-nothing" portfolio of top active funds’ holdings outperformed both the managers and the index over a decade. The study suggests pros excel at stock selection but underperform due to excessive trading and fees. Patak advises investors to be diligent initially but avoid frequent tinkering, as less activity often leads to better long-term results.
