Vivendi returns to the CAC 40, Worldline leaves

Vivendi returns to the Cac 40. Only six months after leaving the flagship index of the Parisian market, the media and communications giant (Canal+, Havas, Prisma Media, etc.) will replace Worldline on December 18. The French electronic payments giant had suffered greatly on the stock market in recent months. It is only valued at 4.45 billion euros and arrives in 66^e position of the Parisian stock market by market capitalization. At the end of October, its price collapsed by almost 60% (-59.24%) in one session, which had never been seen in the history of the Cac 40.

On the other hand, Alstom, also badly hit on the stock market, remains within the index. The railway manufacturer was saved by its classification. In fact, to select the values ​​which will be part of the index, the wise people of the Euronext Scientific Council rely on a ranking established based on two criteria having the same weight: the market capitalization adjusted for the free float and the volumes traded. . Normally, the first 40 values ​​are retained to form the CAC 40. However, to avoid too frequent changes, a “buffer» gives priority to index members ranked among the top 45 in the ranking. This allowed Alstom to remain within the CAC 40 because the group arrives in 45^e position.

Sodexo and Solvay sidelined

Sodexo and Solvay came before Vivendi in this ranking. However, the two groups plan to split into two, which will automatically reduce their market capitalization. Sodexo, the world number two in collective catering, plans to split itself in two in 2024: with on one side, a giant in on-site services (collective catering, security, etc.) which will always be called Sodexo; and on the other, an expert in meal vouchers and gift vouchers. As for Solvay, it must have its split plan ratified this Friday, December 8 at a general meeting. The Belgian chemist plans to create two companies: one bringing together Solvay’s historic activities such as soda ash, which will keep the company’s original name; and the other bringing together specialty materials such as fluoropolymers, grouped within “Syensqo“. The two new entities will be listed on the stock exchange immediately.
