South Korean stocks tumbled Thursday as a broad semiconductor selloff spread from Wall Street to Asia, dragging the Korea Composite Stock Price Index lower after heavy losses in SK Hynix Inc and Samsung Electronics Co. The decline followed a sharp semiconductor selloff on Wall Street overnight after reports that Meta Platforms Inc was exploring a cloud business to sell excess artificial intelligence computing capacity.

The selloff puts U.S.-listed South Korea-focused ETFs in focus, including the iShares MSCI South Korea ETF (NYSE: EWY), Direxion Daily South Korea Bull 3X ETF (NYSE: KORU) and Franklin FTSE South Korea ETF (NYSE: FLKR). These funds provide exposure to South Korean equities, with significant holdings in the country's largest semiconductor makers.
