How to choose an ETF?

📘 Brief Explanation

Selecting an ETF begins with choosing an index that offers the desired market coverage, such as the MSCI World for global stocks. Next, you check the expense ratio (TER), as low fees under 0.3% improve long-term returns. Fund size is also important: a volume over 100 million euros typically signals sufficient liquidity and stability. Additionally, the ETF should track the index’s performance as accurately as possible, which you can assess using the tracking difference. For retail investors, accumulating ETFs are suitable since they automatically reinvest dividends and reduce tax effort. Finally, choose a provider with a good reputation, such as iShares, Vanguard, or Xtrackers.

🔍 Why This Matters

Selecting an ETF is relevant for retail investors because it significantly determines the long-term return and risk of their portfolio. Given the multitude of products available with varying costs, indices, and replication methods, a wrong choice can substantially diminish investment results over decades. Moreover, a systematic selection process allows for precise implementation of a personal investment strategy and helps avoid emotional decision-making errors. The relevance also stems from the fact that ETFs are a central retirement planning tool for many investors, where even small cost differences have an exponential impact.
