What Is the CAC 40?

The CAC 40 is France's premier stock market index, comprising the 40 largest companies listed on Euronext Paris, formerly known as Paris Bourse.

The index initially relied on a total market capitalisation system, akin to the S&P 500. However, in 2003, it adopted a more nuanced approach, similar to the FTSE 100, by incorporating a float-adjusted market capitalization system that considers only freely tradable shares.

The original name of the index was 'Compagnie des Agents de Change', abbreviated as ‘CAC’. After incorporating the top 40 listed companies on Euronext Paris, it adopted the name 'Cotation Assistée en Continu' and became known as CAC 40.

Constituents of the CAC 40 Index

The CAC 40 index showcases some of France's largest corporations, including Total, LVMH (Louis Vuitton), and Airbus. It undergoes quarterly review by Euronext, a European stock exchange, on the third Friday of March, June, September, and December. This review ensures accurate representation and weighting to reflect the overall market by selecting companies based on the past year's regulated turnover combined with a "free-float market cap" system.

Among the top 100 companies by market capitalisation on Euronext Paris, the index prioritises the 1st to 35th spot, while the 36th to 45th is like a buffer zone for entry into the CAC 40 index. In addition, top-performing companies from other Euronext exchanges are occasionally granted access to the index.

How Is the CAC 40 Index Calculated?

Unlike many indices, the value of the CAC 40 index is derived based on a price return methodology. It multiplies the number of outstanding shares with the closing share prices of its member companies. This product is then adjusted by a divisor to arrive at the final index value.

The dynamic nature of the divisor ensures the index constantly adjusts itself based on the initial market capitalisation of the 40 companies and a set baseline. This approach allows the index to reflect the real-time changes in its price movements wherein some companies exert more influence due to their size.

What Drives the CAC 40’s Price?

The CAC 40 price is derived from the share price of its constituent companies and it can be influenced by various factors but here are the index's most influential drivers:

  1. Company Earnings
  2. Due to its market-cap-weighted structure, the CAC 40 places more emphasis on the value of its largest companies. This means changes in the earnings of its largest constituents can heavily influence the index's price movements.

  3. Central Bank Policies
  4. France's central bank operates independently, but the European Central Bank (ECB) significantly influences the France 40 index due to France's adoption of the Euro and the presence of numerous multinational corporations in the CAC 40. The ECB's policies have a direct impact on borrowing costs and spending behaviours among businesses and consumers in the Eurozone including France, consequently affecting the performance of the stock markets and the CAC 40 index.

  5. Economic Events
  6. Elections can have a significant impact on the CAC 40 index, causing fluctuations as seen during the French presidential election in 2017 between Le Pen and Macron. Other major events like global pandemics or farmers' strikes in France can also negatively influence the French 40 index price.

  7. Commodity Prices
  8. Fluctuations in commodity prices can significantly impact the stock prices of relevant French companies, subsequently affecting the overall value of the index. For instance, a decline in oil prices is expected to negatively impact the share price of oil and gas companies within the CAC 40 index.

  9. Economic Data
  10. The French economic health, as indicated by reports on inflation, employment trends, and GDP, serves as a pivotal determinant guiding monetary and fiscal policy decisions that ultimately shape the trajectory of the French stock market and the France 40 index price.

As time progresses, if the value of the contract remains far from the strike price and the expiration date looms, the value of the option declines rapidly. Therefore, timing is a critical factor when entering into options contracts, and the distance from the strike price matters greatly.

This approach involves trading share CFDs* with leverage, providing you with the flexibility to capitalise on its price movements in either direction. You can explore the offerings of prominent French companies such as Sanofi, a global pharmaceutical company, energy titan TotalEnergies, or banking powerhouse BNP Paribas, all significant constituents of the CAC 40 index.
