🎯 ETFs (Exchange Traded Funds)

ETFs are exchange-traded funds that are bought and sold on the stock market just like shares. They combine the diversification of a fund with the intraday liquidity of a stock. There are thousands of them, they replicate virtually any strategy and usually have very low fees — but they have a significant tax disadvantage compared to index funds.

Puntos clave y accionables

  • 1What makes them different from index funds: they trade in real time during market hours. You can see the price every second, buy and sell instantly through a broker.
  • 2TAX DISADVANTAGE: ETFs do NOT have the tax deferral benefit of funds. If you transfer from one ETF to another, you pay capital gains tax as a normal sale. That is why for very long-term investing, index funds win the battle.
  • 3Types by strategy: physical replication (they buy the actual stocks), synthetic replication (they use derivatives — more efficient but with counterparty risk).
  • 4Distributing vs Accumulating: distributing (Dis) ETFs pay out dividends in cash; accumulating (Acc) ones reinvest them automatically. For long-term investing, Acc is better — it avoids paying income tax on each distribution.
  • 5UCITS ETFs vs US ETFs: in Europe you can only buy UCITS ETFs (European regulation). The famous American ETFs (VTI, VOO, etc.) are banned for European retail investors. Their UCITS equivalents are IWDA, VWCE, CSPX, VUAA...
  • 6Spreads and volume: be careful with low-volume ETFs — the bid/ask spread can eat into your returns. Choose large ETFs (>1,000M€ in assets under management) to minimize spread impact.
  • 7Which brokers to use: Interactive Brokers (cheapest and most complete), DEGIRO (simple and affordable), Trade Republic (zero commissions on investment plans).

Errores comunes a evitar

  • ⚠️Buying leveraged (2x, 3x) or inverse ETFs thinking they are long-term investments. They are speculative products designed only for intraday trading — the compounding effect destroys them over long periods.
  • ⚠️Trading US-replicating ETFs during European hours. The ETF price can diverge from the real value (NAV) during high volatility, especially around market closes.
  • ⚠️Ignoring taxation and transferring ETFs as if they were funds. Every sale = taxable event.
