An ETF (exchange-traded fund) holds a basket of investments, such as stocks or bonds. These six checks will help you compare your options.
01 What does it invest in?
Check the countries, sectors and largest holdings. A global stock ETF spreads your investment across different markets. A thematic ETF focuses on an area such as robotics or clean energy and can be more concentrated.
Start with what you want to own, then compare ETFs that offer similar exposure.
02 AUM — how big is the fund?
Assets under management (AUM) is the total value invested in the fund.
As a practical starting point, look for at least €100 million. Larger, established funds are generally less likely to close because they are too small to operate economically. Size does not protect you from market losses.
03 TER — what does it cost each year?
The total expense ratio (TER) is the fund’s annual operating cost, deducted automatically within the fund. A 0.20% TER means roughly €20 a year for every €10,000 invested, assuming a constant investment value.
| Annual TER | How to think about it |
|---|---|
| Up to 0.20% | Low. A useful target for broad market ETFs. |
| Above 0.20% to 0.40% | Moderate. Compare similar funds for cheaper options. |
| Above 0.40% to 0.60% | Higher. High for a broad market ETF, but may be reasonable for a specialised or thematic ETF. |
| Above 0.60% | Expensive. Look closely at what you receive for the extra cost. |
These are comparison guidelines, not fixed standards. A higher fee does not promise better returns. Your broker may charge additional fees.
04 Issuer — who runs the fund?
The issuer is the company behind the ETF. Check its experience and whether its website makes holdings, costs and fund documents easy to find.
An established provider is a useful starting point, but a familiar name does not make every fund a suitable investment.
05 Launch date — how long has it existed?
Also called the inception or issuance date, this tells you when the fund started.
Three years or more is a useful preference, giving you some real operating history to review. A newer ETF can still be a good option, particularly if it already has substantial assets and an experienced issuer. Age alone does not guarantee quality or future returns.
06 Accumulating or distributing?
This tells you what happens to the fund’s income.
- Accumulating (Acc): automatically reinvests income inside the fund.
- Distributing (Dist): pays income out to you.
Choose based on whether you want automatic reinvestment or cash payments. Tax treatment depends on where you live.
