Index / Passive Investing
Own the whole market cheaply and let it compound, instead of trying to beat it.
How it works
Passive investing abandons stock-picking and simply owns a broad market index, such as a total-market or S&P 500 fund, at very low cost. The premise, backed by the tough math of active management, is that after fees most active managers lag the index, so buying everything and holding forever captures the market's return with minimal expense and effort. There is no forecasting, timing, or selection; you accept the average and win by keeping costs and taxes tiny. Broad diversification removes single-stock risk, and low turnover compounds efficiently over decades. The trade-off is that you fully ride every bear market down, with no defense.
The trade-offs
✅ Strengths

- Instant broad diversification, no single-stock risk
- Simple, hands-off, and emotionally easy to stick with
⚠️ Weaknesses
- Fully exposed to every crash with no downside defense
- Guarantees market returns, never outperformance
- Cap-weighting concentrates in whatever is most popular
