What is the CAC 40?
In short: The CAC 40 is the index of the 40 largest companies listed in Paris (LVMH, TotalEnergies, Airbus, L'Oréal…). It is the benchmark of the French stock market and you can invest in it through an ETF.
How it is calculated
Each company is weighted by its market value (based on freely traded shares), with a cap. Its composition is reviewed regularly.
A peculiarity
The standard CAC 40 index does not include dividends paid: over long periods it understates what the Paris market really returned.
