What is an ETF? Complete Guide on Trackers and Index Funds

Investing in the stock market can sometimes seem complex, especially for beginners. Among the financial tools praised for their simplicity and efficiency, ETFs, also called trackers or index funds, hold a special place. But what exactly is an ETF? How does it work and why has it become a must-have for individual and professional investors? This complete guide will explain everything you need to know about ETFs to help you start your investment journey with confidence.

Definition: What is an ETF or tracker?

An ETF (Exchange Traded Fund), or tracker in French, is an investment fund listed on the stock market that aims to replicate the performance of a stock market index, such as the CAC 40, the S&P 500, or the MSCI World. Unlike a traditional fund, an ETF is traded continuously on financial markets, like a stock, which offers liquidity and flexibility.

For example, if an ETF follows the CAC 40, its value will evolve according to the performance of the 40 largest French companies listed on the stock market. Buying a share of this ETF means indirectly owning a small piece of each of these companies.

How ETFs work and their main characteristics

ETFs operate according to passive management: they seek to replicate an index without trying to beat it. This approach brings several advantages:

• Low fees: The total expense ratio (TER) of an ETF is generally between 0.1% and 0.5% per year, much lower than the fees of actively managed funds which can exceed 2%.
• Transparency: ETFs publish the exact composition of their portfolio daily, allowing the investor to know precisely what they are investing in.
