Apple whose market capitalization is back below 2 trillion dollars (1 895 billion euros) despite being worth more than 3 trillion dollars a year ago. Tesla lost 12% in one day and Wall Street ended Tuesday, January 3, its first day of 2023 in the red. Indeed, after the annus horribilis of 2022, those who were hoping for a break at the beginning of the year are at a cost.

Last year, the American stock market had its worst performance since the great financial crisis of 2008. Thus, the S&P 500, which represents large companies, fell by a fifth, while the Nasdaq index, rich in technology stocks, lost a third of its value. The Dow Jones performance, which was calculated in a very complex way, with a decline limited to 9.5%, is misleading. In 2022, the entire Bourses world lost 25 trillion dollars, but it is by far the collapse of the tech giants that dominates according to the Bloomberg agency.
