The French CAC 40, the Euronext Paris benchmark index, is changing its method of calculating companies’ weighting in the index to base it on free float rather than on market capitalization. The CAC 40 index is calculated once per 30 seconds from 9:00 until 17:30 (CET).

The CAC 40 is a free float-weighted index, meaning that the weightings of each of the index’s components are determined by the value of shares outstanding to the public.
