CAC

The CAC 40 (Cotation Assistée en Continu) serves as the benchmark French stock market index, encompassing the 40 largest and most liquid companies listed on the Euronext Paris. This index is a pivotal gauge of the overall performance of the French stock market and the broader European economy. Companies in the index are weighted by their market capitalization, which means larger companies have a greater impact on the index's performance.  The CAC 40 today is a key indicator of the French stock market's health and is closely watched by investors globally as a barometer of the French economy.

How to Calculate the CAC 40 Index?

Here’s how to calculate the CAC 40 index:

• Price return is the base used to calculate the index. The computation is based on the number of shares that each constituent currently has in its index multiplied by the most recent price, then divided by the divisor. 
• Based on the base level and the index's original capitalization basis, the divisor is calculated. A consequence of business operations and composition changes is the adaptation of the divisor.
• You can multiply the current price of each of the constituent stocks by its market capitalization weight to determine the index's current value. 
• For each of the 40 stocks, multiply these market values. Divide the total by the current divisor. The real-time index value is provided by this calculation.
• The divisor is frequently changed to maintain the continuity of the index. This adjustment can be impacted by company activities like dividend distribution, stock divisions, and rights issuance.
• For instance, if a company divided its shares, the divisor would be increased to balance out the share price's decline while maintaining the index's value.
• Every three months, the Euronext Index Steering Committee reviews the composition of the CAC 40 Index. A company's inclusion or exclusion may depend on its inclusion in the French stock exchange, changes in its market presence, sector allocation, or other factors.
