Warren Buffett has said repeatedly that most investors should simply buy an S&P 500 index fund. His reasoning is backed by one of the most studied phenomena in finance.
The Data Is Overwhelming
According to SPIVA research, over a 20-year period:
- 92% of actively managed large-cap funds underperformed the S&P 500
- 95% of mid-cap funds underperformed their benchmark
- 97% of small-cap funds underperformed their benchmark
"A low-cost index fund is the most sensible equity investment for the great majority of investors." — Warren Buffett
The Power of Low Fees
Fees compound just like returns — but in reverse:
| Annual Fee | $10,000 Over 30 Years (8% return) |
|---|---|
| 0.03% (VOO) | $98,770 |
| 0.50% (Average ETF) | $89,520 |
| 1.00% (Mutual Fund) | $81,230 |
| 2.00% (Hedge Fund) | $66,270 |
The fee difference is staggering: A 2% fee costs you $32,500 on a $10,000 investment over 30 years.
