AI and technology stocks are at the centre of Wall Street's massive sell-off, with chipmakers, AI-linked companies and data centre players leading the decline. The Nasdaq has entered correction territory, while the Dow Jones plunged 1,833 points in Wall Street's steepest sell-off since April 2025. The rout wiped out gains from Wednesday's post-election rally and weighed on global markets. Indian equities also opened lower on Dhanteras, tracking the global weakness just days ahead of Diwali.
