Investing in an ETF in practice

An ETF, or exchange-traded fund , replicates the performance of a stock market index such as the CAC 40 , the MSCI World or the Nasdaq-100 . It is traded continuously on the financial markets, like a stock.

To learn the basics, we invite you to consult this ETF investment guide offered by XTB, one of the most popular brokers in Europe.

The steps to invest in an ETF

• Choose a reliable online broker
• Open a securities account or a PEA (Equity Savings Plan)
• Select one or more ETFs based on your objectives
• Place a buy order via the broker's platform
• Monitor and adjust your portfolio according to your needs

Why invest in an ETF?

ETFs offer instant exposure to a wide range of assets at low management fees . Unlike traditional investment funds, they are generally passive : they simply replicate an index without trying to outperform it. This avoids additional costs and the potential for human error.

Key advantages of ETFs

• Automatic diversification : a single ETF can cover hundreds of companies
• Low costs : management fees often less than 0.20% per year
• Liquidity : ETFs are bought and sold in real time
• Transparency : the composition is public and mechanically replicated

Understanding the different types of ETFs

There are several types of ETFs, each with its own characteristics. Understanding these differences will help you make a choice that suits your profile.

ETFs by underlying asset type

• Equity ETFs : replicate stock market indices such as the S&P 500 or the DAX
• Bond ETFs : track indices of debt securities (Treasury bills, corporate bonds, etc.)
• Commodity ETFs : allow exposure to gold, oil, or silver
• Sector ETFs : target a business sector (technology, healthcare, energy, etc.)
• Geographic ETFs : focus on a specific region such as Europe , the United States , or emerging markets.

Physical vs. Synthetic ETFs

• Physical ETFs : actually buy the index's assets
• Synthetic ETFs : use derivatives to replicate performance

Physical ETFs are preferred by most individual investors for their simplicity and transparency.

Should I use a PEA or a securities account?

In France, two tax-advantaged investment vehicles allow you to invest in the stock market: the PEA ( ) and the ordinary securities account (CTO). Not all ETFs are eligible for the PEA, but this vehicle offers attractive tax benefits after 5 years.

How to choose a good ETF?

Choosing an ETF depends on your objectives, investment horizon, and risk tolerance. Here are the criteria to consider before buying.

Key elements to analyze

• Key indicator : the most well-known is not always the most efficient
• Management fees : the lower they are, the better.

• replication
  is preferred, as it offers greater transparency and limits counterparty risk associated with derivatives used in synthetic ETFs.
  Physical or synthetic replication depends on the chosen strategy. US ETFs, often physical, are only accessible through a securities account.

• Quotation currency : be aware of exchange rate risk if the ETF is denominated in dollars
• Assets under management : avoid ETFs that are too small (less than €100 million)
• Eligibility for the PEA if you invest within this framework
• Distribution policy : capitalizing (reinvests dividends) or distributing (pays dividends)

Concrete examples of popular ETFs

Here are some ETFs that are among the most used by European investors.

• Lyxor MSCI World (EWLD) : access to global equities (eligible for French equity savings plan)
• Amundi S&P 500 UCITS ETF : US market exposure with low fees
• Xtrackers MSCI Emerging Markets UCITS ETF : for investors seeking growth in emerging markets such as China or India.
• iShares Core MSCI World UCITS ETF : a very popular accumulating version
• Lyxor PEA Nasdaq-100 : Nasdaq ETF eligible for PEA

What strategy should be adopted with ETFs?

ETFs fit perfectly into a long-term investment strategy. The most recommended approach for a beginner is passive management with scheduled investments .

Dollar Cost Averaging (DCA)

Dollar -cost averaging (DCA) involves investing the same amount each month, regardless of market conditions. This helps smooth entry points and limit the emotional impact.

Example of a simple strategy

• €100 per month on a global accumulating ETF
• Allocation: 80% global equities / 20% bonds
• Rebalancing once a year

This method avoids "timing" the market, which is often counterproductive for individual investors. Dollar-cost averaging (DCA) reduces average volatility without significantly sacrificing long-term performance.

Risks to be aware of before investing

Even though ETFs are known to be simple and accessible, they carry risks that should not be overlooked.

The main risks

• Market risk : capital loss if the index falls
• Exchange rate risk : if the ETF is in foreign currency
• Liquidity risk : some lightly traded ETFs may have a high spread
• Risk of tracking error : the ETF may slightly deviate from the index
• Counterparty risk : especially for synthetic ETFs

How much do you need to start?

It is possible to invest in ETFs from €10 to €50 depending on the platform. Some brokers even offer fractional buying, allowing you to buy a portion of an ETF instead of a whole share.

For a beginner, a balanced ETF portfolio can be built with a few hundred euros and will evolve over time with regular contributions.

Conclusion

Investing in an ETF is now one of the simplest and most effective ways to build a diversified, accessible, and high-performing portfolio. Whether through a PEA (French equity savings plan) or a standard brokerage account, with a few dozen or several thousand euros, ETFs are suitable for all types of investors.
