If 90 Percent of Professional Managers Can’t Beat the S&P 500, Why Do You Think You Can

The math behind active management is brutal, and most investors refuse to look at it. Bo Hanson and Brian Preston of the Money Guy Show keep returning to one statistic because it cuts through every clever pitch and every promising fund manager bio. According to SPIVA data, roughly 90% of active US large-cap managers have underperformed the S&P 500 over rolling 15-year periods. These are full-time professionals with research teams, Bloomberg terminals, and direct access to corporate management. Nine out of ten of them still lost to a fund that simply owns everything.
So when a retail investor with a brokerage app and a hunch about NVIDIA thinks they can do better, the honest question is: based on what?
The Sports Betting Parallel
Hanson uses an analogy that lands harder than most index-fund sermons. Sports betting carries an expected loss of over 9% according to the American Gaming Association, yet millions of people place bets every weekend convinced they have an edge. Here is how Hanson framed it:
"If we told you that we have a better system that helps you avoid taking a 9% haircut, you wouldn't get near it. But yet here's the overconfidence of the typical sports bettor, is that they think that they have a better way to make money even though the system is counting on them to lose."
Stock picking runs on the same fuel. The house, in this case, is the collective intelligence of every institutional buyer and seller already priced into the stock you are eyeing. You are competing against Fidelity, Citadel, and Renaissance Technologies, and they are losing to the index too.
Why the Index Keeps Winning
The S&P 500 wins through concentration plus discipline. Look at what you actually own when you buy SPDR S&P 500 ETF Trust (NYSEARCA:SPY): NVIDIA at 7.57%, Apple at 7.16%, Microsoft at 4.40%, Amazon at 3.73%, and Alphabet's two share classes combined for roughly 6%. The index lets winners run and quietly removes losers. No fund manager ego, no quarterly performance pressure, no need to justify holding cash.

The cost difference compounds that structural advantage. SPY's net expense ratio is 0.0945%, sourced from State Street's fact sheet. A typical active mutual fund charges roughly ten times that. Over decades, the fee drag alone explains a meaningful chunk of underperformance.
The returns back that up. SPY is up approximately 22% over the past year and roughly 85% over the past five years. That is the bar most professionals failed to clear. The SPIVA Year-End 2025 scorecard, published by S&P Dow Jones Indices, found that 79% of all active large-cap US equity funds underperformed the S&P 500 in 2025 alone, making it the worst single year for active large-cap managers since 2021. Over the 15-year period ending December 2024, not a single one of 22 US equity fund categories had a majority of active managers outperform their benchmark.

It is worth noting that the data is not without critics. A 2026 study sponsored by the Investment Adviser Association argued that SPIVA overstates underperformance by treating all funds equally regardless of asset size and by counting merged or liquidated funds as automatic underperformers. Applying asset weighting, the study found a closer result. S&P Dow Jones Indices defended its methodology, saying it measures the proportion of funds that underperform independent of fund size, giving a clearer picture of manager skill across the full universe. Both sides agree that the long-run default for US large-cap active management is underperformance.
The Humility Trade
Preston's prescription is short, and it is the hardest pill in personal finance:
"At the very onset, you ought to acknowledge your own limits and biases. Nothing wrong with being intelligent. There's nothing wrong with being a higher IQ, but that doesn't mean that you're an oracle. It doesn't mean that you can accurately predict the future."
Intelligence does not transfer to forecasting. Doctors, engineers, and lawyers blow up brokerage accounts at roughly the same rate as everyone else, often faster because their confidence outruns their humility. History offers cautionary examples at the professional level too. Bill Miller famously beat the S&P 500 for 15 consecutive years, then underperformed catastrophically during the 2008 financial crisis, a reminder that even long streaks of outperformance can reflect the right side of luck more than durable skill.
What to Watch From Here
With the VIX sitting near 15, markets feel calm, which is precisely when retail investors get bold. Calm markets are when overconfidence builds, just before it gets punished. Consumer sentiment, meanwhile, came in at 49.5 in the final June 2026 University of Michigan reading, historically depressed despite a modest improvement from April. The index's current level sits below every reading at the start of the six recessions recorded since the survey began. That disconnect between cheap volatility and worried consumers is exactly the environment where stock pickers convince themselves they see something others missed.
The takeaway from Hanson and Preston is unglamorous and correct: buy the index, keep your costs low, and spend your energy on savings rate and time in the market. The 10% of professionals who do beat the S&P 500 do not stay the same 10% from decade to decade. S&P's Persistence Scorecard consistently shows that top-half fund performance reverts toward the mean, and for large-cap funds the reversion is even more pronounced than a random distribution would suggest. Picking which fund will win next is its own losing game.
