Nasdaq Sinks 4% to Mark Worst Day in a Year

The Nasdaq Composite had its worst day in more than a year after early AI stock selling snowballed in the face of higher bond yields and spending worries. The tech-heavy index sank 4.2%, its worst daily decline since April 10, 2025, according to Dow Jones Market Data. The selling began before the market opened, as Wall Street continued to shed highflying AI stocks after Broadcom's earnings report earlier in the week failed to excite investors after a parabolic run in the past year.
