Three index funds. All cheap. All diversified. But over 30 years, the choice matters more than you think.
This is one of those topics where the conventional wisdom doesn’t quite hold up.
What Each Holds
| Fund | Example | Stocks | Expense |
|---|---|---|---|
| S&P 500 | VOO/FXAIX | 500 US large-cap | 0.03% |
| Total US | VTI/FSKAX | ~4,000 all-cap | 0.03% |
| Total World | VT | ~9,500 global | 0.07% |
30-Year Returns (1994-2024)
- S&P 500: 10.3% annualized
- Total US: 10.1%
- Total World: 8.4%
S&P 500 won the last 30 years. But from 2000-2009, international stocks returned +30% while S&P returned -9%. Decade swings are massive.

I believe this deserves more attention than it gets.
The Real Question
- S&P 500: You believe US tech dominance continues. Simplest.
- Total US: Same + small-cap value premium potential (+0.5-1% if it persists).
- Total World: You do not know which country wins next 30 years. Nobody does. Humble choice.
Our Take
One fund for 30 years: VT (Total World). Not best historical returns, but requires zero predictions. Humility compounds better than conviction.
