CAC 40 Index components | values (FR0003500008)

The CAC 40 is a price index that includes the 40 most actively traded French companies listed on Euronext Paris. The index level is based solely on stock prices and is adjusted only for returns from subscription rights and special payments. The weighting is based on market capitalization and also on the market value in free float shares. Capital measures such as stock splits do not have a distorting effect on the index. The calculation is updated every second during trading hours from 9:00 to 17:30 CET.

The selection of the available stocks must belong to France's most important companies, and the location of the company plays a role, as well as other criteria determined by the index committee. The composition is reviewed quarterly by the index committee and adjusted if necessary. The weight of a company may not exceed 15 percent, and this limit is reviewed annually at the end of September and reduced to this level if it is exceeded.
