ETFs (Exchange Traded Funds) are exchange-traded funds that track a selected index — e.g., S&P 500 or MSCI World. They combine simplicity of investing with broad diversification and low costs. For most individual investors, they are the best form of building a long-term portfolio.
Key ETF Selection Criteria
1. Underlying Index — What Does the ETF Track?
The most important decision. Popular indices:
| Index | Scope | Number of companies |
|---|---|---|
| MSCI World | Developed markets | ~1,500 |
| FTSE All-World | Global (developed + emerging) | ~3,700 |
| S&P 500 | USA, 500 largest | 500 |
| MSCI Emerging Markets | Emerging markets | ~1,400 |
| STOXX Europe 600 | Europe | 600 |
Tip: For simplicity, one ETF on FTSE All-World or MSCI ACWI gives exposure to the entire global stock market.
2. TER (Total Expense Ratio) — Costs
TER is the annual management fee, automatically deducted from fund value. The lower the TER, the more profit stays in your pocket.
- Excellent: 0.05–0.10%
- Good: 0.10–0.25%
- Acceptable: 0.25–0.50%
- Expensive: above 0.50%
A 0.3% TER difference on a 500,000 PLN portfolio equals 1,500 PLN annually — over 20 years this becomes a serious amount.
3. Fund Size (AUM)
Larger funds (>500 million EUR) are safer — lower closure risk, better spreads, better liquidity.
4. Dividend Policy
- Accumulating (Acc) — dividends automatically reinvested → better for capital building, no Belka tax along the way
- Distributing (Dist) — dividends paid to account → passive income, but 19% tax on each payment
For Poles: Accumulating is almost always better tax-wise, especially on IKE.
5. Replication Method
- Physical — fund buys actual stocks from the index (safer)
- Synthetic (swap) — replicates index using derivatives (small counterparty risk)
Most large ETFs use physical replication — prefer this option.
6. Currency and Domicile
- Irish domicile (IE) — most tax-efficient for European investors (lower withholding tax on US dividends)
- Trading currency — EUR or USD is standard; PLN ETFs on WSE have limited selection

Common ETF Selection Mistakes
- Focusing on historical performance — past returns don't guarantee future ones
- Ignoring TER — 0.5% vs 0.1% is a huge difference after 20 years
- Buying distributing without need — you lose on double taxation
- Too many ETFs — 2–3 funds suffice for most investors
- No plan — buy ETF and hold for years, don't trade weekly
