Why ETFs?

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

Global (Stocks)

ETF Index TER AUM Type
Vanguard FTSE All-World (VWRA) FTSE All-World 0.22% ~12 billion EUR Acc
iShares Core MSCI World (IWDA) MSCI World 0.20% ~65 billion EUR Acc
SPDR MSCI ACWI (SPYY) MSCI ACWI 0.12% ~3 billion EUR Acc

USA

ETF Index TER AUM Type
iShares Core S&P 500 (SXR8) S&P 500 0.07% ~75 billion EUR Acc
Invesco S&P 500 (SPXS) S&P 500 0.05% ~20 billion EUR Acc

Bonds

ETF Index TER AUM Type
iShares Core Global Aggregate Bond (AGGH) Global bonds 0.10% ~5 billion EUR Acc

  • mBank (eMakler) — convenient from bank account
  • Bossa — IKE/IKZE with access to ETFs on foreign exchanges
  • DEGIRO — low commissions, Dutch broker

Common ETF Selection Mistakes

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