CAC 40: Complete Guide to Investing and Understanding the Market in 2025

The CAC 40 is the flagship index of the Paris Stock Exchange and has embodied the economic vitality of the forty largest listed French companies since its creation. As stock market investment becomes a major issue for individuals and institutions, it is essential to understand the structure, composition, recent performance, and effective strategies for investing in the CAC 40 in 2025.

What is the CAC 40?

The CAC 40 ("Continuous Assisted Quotation") is a stock market index calculated and published by Euronext Paris. It groups together the most important and liquid companies on the French market, covering a very wide range of economic sectors: luxury, industry, energy, technology, health, etc.

Its composition is regularly updated to reflect as accurately as possible the evolution of the industrial and entrepreneurial fabric of France. The index thus allows one to follow the health and economic dynamism of France while offering investors a diversified exposure to its stock market.

Origin and Evolution of the Index

Launched in 1987, the CAC 40 aimed to provide a real-time table of the financial performance of major French corporations. Initially limited to "Continuous Assisted Quotation," it was extended in 1988 to the 40 largest listed companies. Since then, the CAC 40 has become the absolute reference for following the Parisian market, and has also become an economic barometer for Europe.

In 2025, its role remains more than ever central in investment decisions, institutional management, and the strategy of large private fortunes.

Composition of the CAC 40 in November 2025

The selection of companies in the CAC 40 relies on strict criteria of market capitalization, liquidity, trading volume, and sectoral representativeness. The index covers all major sectors of the French economy:

Industry: Airbus, TotalEnergies, Saint-Gobain, Michelin, Schneider Electric
Consumer Goods: L’Oréal, Danone, Pernod Ricard, Hermès, Kering
Services: Capgemini, Accor, Teleperformance, Publicis Groupe
Technology: Dassault Systèmes, STMicroelectronics, Atos
Finance: BNP Paribas, Société Générale, Crédit Agricole, AXA
Healthcare: Sanofi, EssilorLuxottica, Eurofins Scientific
Energy & Environment: Engie, Veolia Environnement, Vinci

It is essential to note that Canal+ S.A. does not belong to the CAC 40. Contrary to some common beliefs, Canal+ is a subsidiary of the Vivendi Group and is not separately listed. If one wishes to be exposed to this sector, one must therefore focus on Vivendi, which is not a member of the CAC 40 as of November 11, 2025.

Top Values of the CAC 40 in November 2025

LVMH - Global luxury leader, with its last quoted price at 595.50 €.
Hermès - Dominant position in high-end craftsmanship (2,165.00 € and a strong increase of +6.86% during the session of November 11, 2025).

Renault - Automotive industry, 35.77 € (+3.32%).

The sector diversity of the CAC 40 allows investors to benefit from an evenly balanced exposure to both French and international economic dynamics.

Recent Performance of the CAC 40

The CAC 40 showed solid performance during the session of November 11, 2025, closing at 8,159.6 points with an increase of +1.25%. This rise was mainly driven by the brilliant results of luxury giants (LVMH, Hermès, Kering) and the recovery of the automotive sector.

Over the past few years, the CAC 40 has demonstrated steady growth, punctuated by periods of volatility linked to global crises or monetary policies. Over the period 2015-2025, the overall evolution of the index remains positive, French values having adapted to global changes and economic challenges.

The performance of the CAC 40 is also influenced by multiple factors, including:

Global economic conditions – Trade tensions, health crises, and geopolitical issues play a central role in market volatility.
Monetary policies – Central bank decisions on interest rates directly affect the growth potential of listed companies.
Financial results of companies – The quarterly and annual reports of CAC 40 members can trigger upward or downward movements of the index based on the quality of the results.
Sector movements – A sector can boost the index upwards (luxury, technology) or penalize it (finance, energy) during turbulent times.

Sector Analysis: The Luxury Sector in Strength

The luxury sector particularly illuminates the CAC 40 in 2025. LVMH, Hermès, and Kering demonstrate global power and the ability to resist negative economic cycles thanks to the attractiveness of their brands, their innovation, and their commercial strength. LVMH confirms its status as a global leader, both by its market capitalization and its growth.

The progress of Hermès, with a remarkable increase during the latest session, reflects investor enthusiasm: the international demand for high-quality products remains very strong, driven by Asian, American, and European clientele.

This strategic sector for France gives the CAC 40 a unique competitive advantage on the international stage and attracts foreign capital, enhancing the visibility of the Parisian market.

Example of NOTABLE COMPANIES NOT INCLUDED in the CAC 40

It is crucial to correct some misconceptions:

Canal+ S.A. is not listed on the Paris Stock Exchange and does not appear in the official list of the CAC 40. Investors seeking exposure to the media sector should turn to Vivendi, parent company of Canal+ and a major player in the media and entertainment market. However, Vivendi is also not included among the members of the CAC 40 as of the reference date.
No figures concerning market capitalization, stock price, dividends, debt, or ratios for Canal+ S.A. are available publicly because this entity does not have an independent listing.
Information of the type "Canal+ S.A. listed under the symbol CAN.L with a current price of 232 € and detailed financial data" is factually incorrect and must be excluded from any serious analysis of the CAC 40.
