Massive market selloff affecting millions of Americans’ retirement accounts and investment portfolios, with tech sector leading decline
The Morning Brief Desk · · Updated June 18, 2026 · How the Brief is made
The S&P 500 fell 3.2% Friday, erasing $1.8 trillion in market value. Technology stocks led a broad selloff. The Nasdaq Composite declined 1,121 points. This was its biggest daily fall since early 2025 and the largest point drop on record.
The decline ended a two-month rally for major indexes, with artificial intelligence-related stocks taking the worst of the selling pressure. The tech-heavy Nasdaq fell 6.8%, while the Dow Jones Industrial Average dropped 2.1%. Market winners shared defensive characteristics as investors rotated away from high-growth technology names that had driven recent gains.
