ETFs: funds that track a stock market index
An ETF is an investment fund that automatically tracks a stock market index (such as the CAC 40). You buy a unit in this fund and benefit from the index’s performance without having to select individual shares.

What is an ETF?
ETF stands for ‘Exchange Traded Fund’. It is an investment fund that exactly replicates the composition of a stock market index (an index is a list of shares representative of a market).
Imagine you want to invest in the 40 largest French companies. Instead of buying the 40 shares one by one, you buy a single unit of an ETF that automatically holds all 40 of these shares. It’s much simpler.
The ETF is listed on the stock exchange in the same way as an ordinary share. You can buy and sell it at any time during trading hours (when the stock exchange is open), which makes it highly liquid (easy to convert into cash).
How does an ETF work?
An ETF is based on a simple mechanism: a fund manager (a specialist company) buys all the shares that make up the index, in the same proportions. If the CAC 40 index contains40 %s of banking shares, so does the fund.
When you buy a unit in an ETF, you become the owner of a fraction of all those shares. If the index rises by 10 %, your ETF also rises by 10 %. If the index falls by 5 %, your ETF falls by 5 %.
The management fees for an ETF are generally very low (often between 0,1 % and 0,5 % per year). This means that if you invest 1 000 €, you pay the fund manager just 1 to 5 € per year. This is much cheaper than a fund actively managed by an expert.
The benefits of ETFs
Simplicity : Instead of choosing 40 different shares, you buy just one. You don’t need to be an expert to analyse companies.
Immediate diversification : With a single ETF, you gain exposure to dozens or even hundreds of companies. If one falls, the others may offset the loss.
Reduced fees : ETFs are much cheaper to manage than traditional funds. These savings are passed on to your return.
Flexibility : You can buy and sell your ETF at any time during trading hours, just like a normal share.
Risks you need to be aware of
An ETF tracks its index, whether it rises or falls. If the market crashes, so does your ETF. For example, during the 2008 crisis, CAC 40 ETFs lost more than40 %s of their value.
ETFs do not protect you against market risk. You may lose some or all of your initial investment.
Be careful not to confuse ETFs with insurance. An ETF is not a savings account: it is not guaranteed. Investing in an ETF means accepting a degree of risk in the hope of achieving better long-term returns.
📖 Definitions
- Stock market index
- A list of shares representative of a market. The CAC 40 comprises the 40 largest listed French companies.
- Liquidity
- The ease with which an investment can be converted into cash quickly. An ETF is highly liquid as it can be bought and sold on the stock market in a matter of seconds.
- Diversification
- Spread your money across several different investments to reduce risk. An ETF automatically diversifies your portfolio.
- Management fees
- The annual fees charged by the fund manager to administer and manage your investment.
- Yield
- The profit (or loss) you make on your investment, usually expressed as a percentage.
💡 A practical example
You have 1 000 € and wish to invest in the French economy. You buy a unit in an ETF that tracks the CAC 40 at 1 000 €. This ETF comprises the 40 largest French companies. After one year, the CAC 40 index has risen by 8 %. Your ETF is now worth 1 080 € (8 % profit). You paid 5 € in management fees (0,5 % per year). Your net profit is therefore 75 € (1,080 - 1,000 - 5).
⚠️ Risks you need to be aware of
- An ETF falls when the index falls: you may lose money in the short term
- Concentration risk: if the ETF tracks a single sector (for example, technology), a crisis in that sector will have a significant impact on your investment
- Currency risk: some ETFs track foreign indices and may be affected by currency fluctuations
- No capital guarantee: unlike a savings account, your money is not insured
✅ Key points to remember
- An ETF is a fund that automatically tracks a stock market index, without the involvement of an expert fund manager
- Buying an ETF means buying a single unit that comprises dozens or hundreds of shares: it’s simple and diversified
- ETF fees are very low (0.1 to 0,5 % per annum), which improves your net return
- An ETF rises and falls in line with its index: it is not a risk-free investment
- ETFs are well suited to novice investors who want to invest simply and for the long term
