Common Mistakes When Choosing ETFs

1. Picking the cheapest ETF without checking liquidity The difference between a 0.07% and 0.22% TER amounts to just €15 per year on a €10,000 investment. The bid-ask spread can cost you more if liquidity is poor.

2. Over-diversifying Holding 10+ different ETFs doesn't meaningfully improve diversification compared to 2–3 well-chosen funds.

3. Ignoring tax implications In many countries, distributing ETFs trigger dividend taxes annually. Accumulating ETFs are often more tax-efficient for long-term investors.

4. Market timing Trying to time the perfect entry point usually results in worse returns than consistent, regular investing.

Where to Buy the Best ETFs — Recommended Brokers

For investing in the ETFs above, consider brokers with full access to European exchanges:

Key Takeaways — Best ETFs 2026

2. Simplicity beats complexity — 1–3 ETFs is enough for most investors

4. Liquidity matters more than the lowest TER — paying 0.05% more for reliable execution is worth it
5. Accumulating beats distributing — for tax efficiency in most European countries

FAQ

What is the difference between an accumulating and a distributing ETF?

An accumulating ETF reinvests dividends automatically inside the fund, so your unit price grows over time. A distributing ETF pays dividends out to your brokerage account as cash. For long-term investors in most European countries, accumulating ETFs are typically more tax-efficient because they avoid annual dividend withholding events.

Is one global ETF like VWCE enough for a long-term portfolio?

For most long-term investors with a 10+ year horizon, a single broad global equity ETF can be a reasonable core position because it already covers thousands of companies across dozens of countries. Whether it is "enough" depends on your risk tolerance, time horizon, and need for bonds or other asset classes. This is general information, not personalised investment advice.

What does TER mean and why does it matter?

TER (Total Expense Ratio) is the annual cost charged by the fund as a percentage of assets, deducted automatically from the fund's NAV. A 0.20% TER on a 10,000 EUR position is roughly 20 EUR per year. Small TER differences compound meaningfully over decades, so cost is one of the few variables an investor can reliably control.

How do I evaluate ETF liquidity beyond just looking at TER?

Look at average daily trading volume, the typical bid-ask spread, total fund size (AUM), and how many market makers quote the ETF on your exchange. A larger, more liquid ETF usually has a tighter spread, which lowers your real cost of entering and exiting positions. For long-term buy-and-hold, picking a multi-billion-EUR fund on a major European exchange is generally a safer default.

Are sector or thematic ETFs a good idea for beginners?

Sector and thematic ETFs (technology, clean energy, AI) are more concentrated and historically more volatile than broad market funds. They can also overlap heavily with positions you already hold inside a global ETF. Beginners are typically better served by starting with a broad core portfolio and only adding thematic exposure once they understand the risks and their own goals.
