John Bogle launched the first retail index fund in 1976. His idea — own the whole market at rock-bottom cost instead of trying to beat it — has since been validated by decades of data: 80%+ of actively managed funds underperform their benchmark index over 10+ years.
The three major brokerages compared
| Brokerage | Account minimum | Best index fund | Expense ratio |
|---|---|---|---|
| Fidelity | $0 | FZROX (Total Market) | 0.00% |
| Schwab | $0 | SWTSX (Total Market) | 0.03% |
| Vanguard | $0 (ETF) | VTI (Total Market ETF) | 0.03% |
Which index: S&P 500, Total Market, or World?
- S&P 500 (VOO, FXAIX, SPY): 500 largest US companies. The benchmark. ~10-11% historical annual return. Simple and solid.
- Total US Market (VTI, FZROX, SWTSX): ~3,500 US companies including small/mid-caps. Marginally more diversified than S&P 500 with near-identical historical returns.
- Total World (VT): ~9,000 companies globally. More diversified, slightly lower historical returns than US-only — but reduces home-country risk.

Dollar-Cost Averaging: the most reliable entry strategy
Invest a fixed amount on a fixed schedule regardless of market conditions. $500 on the 1st of every month buys more shares when markets are down and fewer when they're up — automatically averaging your cost basis down over time. It eliminates the impossible task of "timing the market."

💡 The one mistake beginners make
They wait for the "right time" to invest. Research consistently shows time in the market beats timing the market. The investor who put $10,000 into the S&P 500 at the worst possible time each year for the past 20 years still significantly outperformed holding cash. Start now, automate, don't check it obsessively.
