How to Choose ETF — Criteria, Comparison and Popular Funds

Quick Answer

To choose an ETF, first pick the underlying index — a single fund on FTSE All-World or MSCI ACWI gives exposure to the entire global market. Then minimize cost: a good TER is 0.05-0.25%, since a 0.3% difference on 500,000 PLN equals 1,500 PLN a year. Prefer a fund size above 500 million EUR, physical replication, and Irish domicile (IE) for lower withholding tax. For Polish investors, accumulating (Acc) ETFs are usually more tax-efficient than distributing, as they avoid the 19% Belka tax on each dividend. Two to three funds suffice for most portfolios.

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:

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

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

FAQ

What is TER and why does it matter when choosing an ETF?

TER (Total Expense Ratio) is the annual cost charged by the fund manager, deducted automatically from the ETF's net asset value. A difference of 0.3 percentage points may seem small, but compounded over 20 years on a six-figure portfolio it can cost tens of thousands of PLN. For passive index ETFs, lower TER is almost always better — many global equity ETFs are available with TER below 0.20%.

What is a good minimum AUM for an ETF?

A fund size (Assets Under Management) above 100 million EUR is generally considered safe, and above 500 million EUR is preferred. Larger AUM reduces the risk of fund closure (which forces taxable liquidation), improves bid-ask spreads, and generally signals better liquidity on European exchanges like Xetra or LSE.

Physical vs synthetic replication — which is better?

Physical replication means the ETF actually holds the underlying stocks, so it carries no counterparty risk. Synthetic (swap-based) replication uses derivatives with a counterparty and may offer better tracking on some indices (e.g., S&P 500 for European investors due to tax efficiency). For long-term core holdings, most investors prefer physical replication; synthetic can make sense for specific tax-optimized strategies.

Should I choose accumulating or distributing ETFs as a Polish investor?

For most Polish investors, accumulating (Acc) ETFs are more tax-efficient because dividends are reinvested inside the fund and there is no immediate 19% Belka tax event. Distributing (Dist) ETFs pay cash dividends, which trigger tax at each payout. Inside an IKE wrapper, the difference matters less because IKE shields gains and dividends from Belka tax.

Where can I find the KID (Key Information Document) for a UCITS ETF?

UCITS ETFs are required to publish a KID (Key Information Document) on the issuer's website (e.g., iShares, Vanguard, SPDR, Invesco). The KID summarizes objectives, risk indicator (SRI 1-7), costs, and past performance scenarios. This guide is general educational content, not personalized investment advice — always read the KID and prospectus before investing.
