About the CAC 40 index
- CAC 40® stands for “Cotation Assistée en Continu 40” (continuous stock quotation).
The name was chosen to make a link with the previous name of the Paris stock exchange, “Companies des Agents de Change”.
The launch of the index coincided with the French stock market switching to electronic trading in 1986:
- 31 December 1987: the value of the index was fixed at 1,000 points
- 15 June 1988: official launch of the index
The CAC 40® index was created by the Société des Bourses Françaises (SBF) and the name of the French exchange at the time. The index was originally created to support the futures market (MATIF) and the options market (MONEP).
- An earlier name for the CAC 40® was to be the ION 40 which stands for “Indice Options négociables” (traded options index).
- The CAC 40® was created according to international standards for options indices. Its aim was to be a fixed point of reference for investors.
