90% of active traders underperform buy-and-hold; trading costs (commissions, taxes, spreads) eat most of outperformance attempts.
Trading 10 times per year: ~0.5% annual cost (commissions + spreads). Plus short-term capital gains tax (37% vs 15–20% long-term). Average trader needs 13%+ annual returns just to break even vs buy-and-hold at 10%. Statistically, almost nobody achieves this.
Cost of active trading (10 trades/year on $100K)
| Cost | Per trade | Annual (10 trades) | % of capital |
|---|---|---|---|
| Commissions (even $0 now, spreads cost) | $20–50 (bid-ask) | $200–500 | 0.2–0.5% |
| Short-term capital gains tax (avg gain 10%) | $1,000 gain × 37% = $370 tax | $3,700 total taxes | 3.7% |
| Total annual cost | — | ~$4,000–$4,500 | 4–4.5% |
Performance reality
- S&P 500 average annual return: ~10%
- Average active trader needs: 10% + 4.5% (costs) = 14.5% to break even
- % of traders beating 14.5% annually: ~5–10% (and usually by luck, not skill)
When active trading might work
- You're an experienced trader (< 10% of traders)
- You have edge (information, skill, technology) most don't
- You enjoy it as a hobby (cost is entertainment, not expecting returns)
- You're trading illiquid securities with exploitable inefficiencies
When buy-and-hold wins (for almost everyone)
- Full-time job; no time for active trading
- Want passive, low-stress investing
- Statistically confident in mean reversion
- Can't beat 14.5% annual returns consistently
Recommendation: Buy-and-hold index funds for 90%+ of portfolio. If you want to trade, allocate 5–10% as "learning capital" and accept 20–30% losses (treat as tuition). Protect the bulk with passive strategy.
