Chip stocks slump, Nasdaq 100 loses 6.4 percent

According to CNBC, the Nasdaq 100 fell 6.4 percent on 5 November 2026. About $2.3tn in market value was lost. The Philadelphia Stock Exchange semiconductor index dropped 12 percent, Nvidia and Qualcomm each more than 9 percent.

The reports cite concern that a slower data center build-out could follow as the reason. That is an interpretation by market observers, not a statement by the companies.
