Concurrently, the VIX volatility index surged 23.05%, reflecting heightened market anxiety.

The sell-off was particularly severe within the AI hardware and semiconductor sectors. Micron led the losses with a 12% drop, followed by Astera Labs falling 9.05%, Marvell declining 8.86%, Teradyne down 8.73%, and Arm retreating 8.36%.
