EFF: In an interview with Client Insights host Dan Richards, I explain the key findings of the paper "Luck vs. Skill in Mutual Fund Performance" that Ken French and I published in 2010. Looking at funds over their entire lifetimes, only 3% demonstrate skill after accounting for their fees, and that's what you would expect purely based on chance. Even the active funds that have generated extraordinary returns are unlikely to do better than a low-cost passive fund in the future.
