JOHANNESBURG - A selloff of AI-linked technology stocks is dragging markets around the world.
South Korea's main market dived 10% earlier today - weighed by chip makers such as Samsung Electronics.

Rocket maker and AI company SpaceX has fallen more than 20% in three days, giving up the gains after its Initial Public Offering earlier this month.
Some are calling it a normal market correction or profit taking.
