Time IN the Market > Timing the Market

⏰ People with PhDs, supercomputers, and Bloomberg terminals spend their careers trying to buy the dip at the exact bottom. They lose, consistently, to someone who put in the same amount every month and took a nap. The math behind why comes down to one number — and it's about 10 days.

💡 Key idea

Investors who do NOTHING usually beat investors who do SOMETHING.

🧠 Why it matters

'Timing the market' means trying to buy at lows and sell at highs. Studies (Fidelity, JPMorgan, Vanguard) repeatedly show that missing just the 10 BEST days over 20 years cuts your return roughly in HALF. And the best days usually cluster right after the worst ones.

🌍 In the real world

📉 $10,000 in the S&P from 2003–2022 fully invested: ~$65,000. Missing just the 10 best days: ~$30,000. Missing the best 30 days: ~$12,000. Those 'best days' often happened the week AFTER a crash, when everyone panic-sold.

📌 Takeaways

Best days cluster near the worst days
Missing 10 best days = halve your return
Auto-invest beats reacting to news

✅ Test yourself

Best move when the market drops 15% in a week?

Sell everything
Keep buying on schedule
Wait until it 'feels safe'
Move to gold

Answer: B · Keep buying on schedule

Selling locks in losses; waiting usually means missing the bounce. Dollar-cost averaging keeps you buying when prices are LOW.

What does missing the 10 best market days over 20 years typically do?

Barely matters
Doubles your return
Roughly halves your return
Triples your return

Answer: C · Roughly halves your return

Roughly halves it. The best days almost always come right after the worst days, when scared investors are on the sidelines.
