About CAC 40 Index: Meaning, Components, Calculation & Live Market Insights

The CAC 40 Index is the premier stock market benchmark of France and one of the most influential indices in Europe.

These companies represent a broad spectrum of industries including luxury goods, banking, energy, healthcare, telecommunications, and industrial manufacturing.

Launched in 1987, the CAC 40 has become a key measure of the French economy’s health and an important indicator for European investors.

A special committee reviews and updates the list of 40 companies four times a year. Firms can be added or removed based on market size, trading volume, and financial transparency.
