What was corrected
The article's fee table gave $100,000-at-7% 30-year values of about $753,000, $622,000, and $558,000; said EMH makes outperformance impossible; said every historical 20-year real return was positive; gave one fixed SPIVA underperformance rate; and framed Barber-Odean, DALBAR, and Carhart as universal causal rules.
Recomputed the fee table at the stated net returns, qualified the EMH and 20-year-return claims, scoped the SPIVA figure, and framed the investor-behavior studies as sample findings rather than universal laws.
Why this is better
The fee figures were an arithmetic error and the other claims were more absolute than the evidence supports. Corrections recompute the table and scope the claims rather than adding new sources.
