CAC40

CAC40 [EN] - The CAC-40 Index is the benchmark tracking index for the Paris Bourse. Started in December of 1987 with a value of 1000, the index is comprised of the 40 largest and most liquid stocks trading on the exchange. The CAC-40 is a 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. This prevents a large company that only issues a small amount of its shares from having a disproportionate amount of influence on the index's value. Similar to how the S&P 500 is a subset of the S&P 3000, the CAC-40 is a subset of the larger SBF (Societe des Bourse Francais) 250.
