Before the Creation of the CAC 40 Index

The CAC 40 index is actually a relatively recent stock market index used to measure the financial health of the French economy. Before 1988, there was indeed an INSEE index of the Paris Stock Exchange to measure these performances and which was quintupled in the 1920s and then again in the 1950s, despite the geopolitical uncertainties on the occasion of these two periods of economic growth.

During the 1960s and 70s, this trend came to an end with the gradual diversion of small investors from a permanently downward trend in the Paris Stock Exchange and a 7% drop in French holding shares.

But in the early 1980s and despite a more gloomy economic context, there was an upward trend in this index with a recovery in stock market prices. Indeed, financial globalization then took its first steps in the world of finance and the reforms carried out by François Mitterrand in the banking system with the banking law of 1984 contributed to blowing up the Paris stock market as well as that of London in 1986 and led to the creation of the CAC 40 stock market index in December 1987.

Birth of the CAC 40 stock market index

It was therefore following the crash of October 1987 that the CAC 40 was born. This index thus changed the monopoly of financial and stock market transactions.

It should be remembered that these transactions were once directly managed by ministerial officers and stockbrokers. Following the edition of law 88-70 of January 1988, this management was entrusted to brokerage firms. Moreover, the meaning of the name CAC at that time was not the same as now and corresponded to Compagnie des Agents de Change.

The CAC 40 index was defined with a base value of 1 points on December 000, 31. It will reach its lowest point on January 1987, 29 at 1988 points. But it was not until June 893.82, 15 that the CAC 1988 truly saw the light of day. He will end this first year with a course at 40 points.

The Speculative Bubble and the 2000 Record

Thanks to the speculative bubble in the values ​​of the telecommunications, media and technology sector, the CAC 40 index reached a historic high on September 4, 2000 at 6 points before falling back to 944.77 points. on March 2, 401.15, its lowest level since 12 and due to production overcapacity in Europe and the United States.

Since the beginning of December 2003 and like the main world indices, the CAC 40 takes into account both the stock market capitalization of the companies which enter into its composition but also the free float and therefore the securities actually available on the stock market.

Several Bullish and Bearish Trends from 2007 to 2011

  • The CAC 40 index will then experience a rise to 6 points on May 000, 2 after a 2007% increase in points in just four years and even reached 150 points on June 6 of the same year. In July 168.15, the composition of the CAC 1 index represented more than 2007% of the total capitalization of the Paris Stock Exchange, i.e. 40 billion euros, before falling back to less than 70 billion euros at the start of the year. 1.

It was during the session of October 10, 2008 that the index recorded its largest daily increase since its creation with an increase of 13% to 2008 points and its largest fall took place shortly before October 11.8, 3 with a drop of 531.50% to 6 points.

  • From 2017, the CAC 40 includes companies from the technology sector with the entry of the Atos group in March, then the STMicroelectronics group in September of the same year and finally Dassault Systèmes in September 2018. In June 2019 and still in this same sector of activity, it is the company Thalès which is entering the composition of the index. The technology sector is thus gaining a place in an index that has long been dominated by financial and industrial stocks.

  • On Thursday March 12, the biggest loss of points in the CAC 40 index will occur with a drop of 12.28% and a price that will end the session at 4 points, the worst session since the index was created.
