CAC 40

CAC 40 is a stock market index that represents the 40 largest and most liquid Euronext Paris-listed companies, such as Sanofi, TotalEnergies, and L'Oréal. The index is widely regarded as a benchmark for the French economy, alongside other major indices like the DAX and FTSE 100. It is maintained by NYSE Euronext, a stock exchange operator that also manages the Amsterdam Stock Exchange and the Brussels Stock Exchange. The CAC 40 is often compared to other prominent indices, including the S&P 500 and the Nikkei 225.

Introduction

The CAC 40 is a free-float market capitalization-weighted index, meaning that the weight of each component stock is proportional to its market capitalization, adjusted for the proportion of shares that are freely available to trade, similar to the S&P 500 and the Euro Stoxx 50. This methodology is also used by other major indices, such as the FTSE 100 and the DAX. The index is calculated and maintained by NYSE Euronext, which also operates the Euronext Paris stock exchange, where companies like Airbus, Renault, and Vivendi are listed. The CAC 40 is widely followed by investors and financial analysts, including those at Goldman Sachs, Morgan Stanley, and JPMorgan Chase.

History

The CAC 40 was created in 1987 by the Paris Bourse, the predecessor to Euronext Paris, with the goal of providing a benchmark for the French stock market, similar to the Dow Jones Industrial Average in the United States. The index was initially composed of 40 companies, including Peugeot, Renault, and TotalEnergies, and was calculated using a market capitalization-weighted methodology, similar to the S&P 500. Over the years, the CAC 40 has undergone several changes, including the addition of new companies, such as Sanofi and L'Oréal, and the removal of others, such as Alcatel-Lucent and STMicroelectronics. The index has also been affected by major events, including the European sovereign-debt crisis and the COVID-19 pandemic, which have impacted companies like Air France-KLM and Accor.
