Chapter 10
Choose an ETF
Now it's time to pick your ETF. This is easier than you think.
There's no single "best" ETF. The best one is the one that matches your comfort level — because the only ETF that works is one you can keep adding to for years without panicking.
Ask yourself one question
How comfortable am I with ups and downs?
- If a 30% drop would keep you up at night → pick a calmer option
- If you can watch your money drop and think "whatever, I'm in this for 20 years" → you can handle more risk
Higher risk = higher potential returns, but also wilder swings. Lower risk = calmer ride, but slower growth.
Three solid options
ACWI (All-World ETF)
Invests in 3,000+ companies all over the world — US, Europe, Asia, emerging markets.
- Most diversified (safest spread)
- Calmest ride
- ~8% per year historically
Best for: people who want broad, global exposure and a smooth experience.
S&P 500
Invests in the 500 biggest US companies — Apple, Microsoft, Amazon, Google, etc.
- Strong long-term performance
- More ups and downs than ACWI
- ~12% per year historically
Best for: people who want a good balance between growth and stability.
Nasdaq 100
Invests in the 100 biggest US tech companies.
- Highest growth potential
- Wildest ups and downs
- ~15% per year historically
Best for: people who are comfortable with big swings and want maximum growth.
What €250 per month becomes
| ETF | 5 years | 10 years | 20 years |
|---|---|---|---|
| ACWI (~8%) | ~€18,300 | ~€45,500 | ~€147,000 |
| S&P 500 (~12%) | ~€20,300 | ~€58,000 | ~€230,000 |
| Nasdaq (~15%) | ~€22,000 | ~€72,000 | ~€360,000 |
(Total invested over 20 years: €60,000)
The difference is dramatic over long periods. But remember: higher returns always come with bumpier rides.
Simple decision guide
- Want calm and global → ACWI
- Want growth with balance → S&P 500
- Want maximum growth, can handle the rollercoaster → Nasdaq 100
Key takeaway
Don't overthink this. Pick something that matches your personality, and stick with it for years. Consistency matters more than picking the perfect ETF.
