CAC 40 Index — Level, Chart & Constituents

What the CAC 40 measures

The CAC 40 is a stock market index that tracks the performance of the 40 largest companies listed on the Euronext Paris exchange in France. It is the main barometer of the French equity market and a widely followed proxy for the broader European sector. Because the index is market-capitalisation weighted, the largest companies by value have the greatest influence on its movements. The CAC 40 is part of the European index landscape alongside peers such as the DAX, FTSE 100, AEX, Euro Stoxx 50, FTSE MIB, IBEX 35, and the broader STOXX Europe 600.

Key numbers explained

• The current CAC 40 level is 8,123.41 points, which is the index's snapshot valuation at the time of the quote; it is not a price but a calculated number reflecting the weighted value of its constituents.
• Today's trading range was 8,112.22 – 8,199.66 points, showing the lowest and highest level reached during the session.
• The price change today is -0.39%, indicating a modest intraday decline relative to the previous close.
• Over the last 52 weeks, the index has ranged from a low of 7,505.27 to a high of 8,755.03, illustrating the spread of returns over the past year.
• The index is denominated in EUR, so its level reflects the euro-denominated value of the basket of shares.
• The CAC 40 is a capitalisation-weighted index, meaning each company's weight is proportional to its total market value.

What to watch

Investors tracking the CAC 40 typically monitor macroeconomic data, European Central Bank policy, and corporate earnings from its large-cap constituents. Movements in the euro, oil prices, and global bond yields can also influence the index's direction. Because the CAC 40 is heavily exposed to sectors such as banking, luxury goods, and industrials, sector-specific news and currency fluctuations are relevant factors to observe.
