Le Nasdaq enregistre sa plus forte chute depuis août alors que l’optimisme autour de l’IA s’évapore
La bulle de l'intelligence artificielle éclate - et les marchés paient le prix.
Réalité brutale pour les technos
Le Nasdaq plonge de 4,2% en séance, pire performance depuis dix mois. Les géants du secteur, portés par le hype de l'IA, subissent des corrections à deux chiffres. Les investisseurs réalisent soudain que les promesses de revenus miraculeux mettront des années à se concrétiser - si elles se concrétisent un jour.

Although shares later recovered, the episode showed how quickly sentiment can swing.
As big tech fell, defensive groups such as utilities, real estate, and consumer staples rose. Roughly 7 out of 10 S&P 500 stocks finished higher.
Even with the setback, tech has been the engine of the market’s latest climb. The S&P 500 information technology sub-index has gained 14 per cent since mid-May, led by AI-linked names including Oracle and AMD.
