South Korea stocks plunged Friday, leading losses in the region, as the slump in Wall Street tech names overnight spread into Asia, dragging benchmark indexes lower.

The Kospi was last down 5.01%, with heavyweights Samsung Electronics and SK Hynix dropping 4.34% and 7.57%, respectively. The small-cap Kosdaq index fell 4.14%.

In a move that could pressure South Korea’s tech sector further, the country’s labor minister urged its biggest technology companies to distribute more of the gains from the AI-driven semiconductor boom with workers and suppliers, saying record profits risk exacerbating income inequality.

Japan’s benchmark Nikkei 225 lost 1.53%.

Australia’s S&P/ASX 200 was 0.61% lower.

Hong Kong’sย Hang Seng indexย was down 0.81%, while the CSI 300 was marginally lower.

India’s Nifty 50 was slightly higher, while the BSE Sensex was up 0.23%.

Overnight in the U.S., theย Dow Jones Industrial Averageย rallied to a fresh all-time high, while theย Nasdaq Compositeย underperformed as investors appeared to rotate out of chip names in favor of non-tech stocks.

The 30-stock Dow jumped 874.86 points, or 1.73%, to close at a record 51,561.93. The Nasdaq lost 0.09% and ended at 26,830.96, while theย S&P 500ย rose 0.41% to 7,584.31.

The rotation was sparked by a sell-off inย Broadcomย that led investors to pare exposure to AI-linked stocks. The chipmaker slid more than 12% after itsย fiscal second-quarter revenue missed estimates. Chip names, which led the latest leg higher in the market’s rally to record levels, fell broadly. Theย VanEck Semiconductor ETF (SMH)ย lost more than 1%.ย Arm Holdingsย shed more than 4%, whileย Micron Technologyย fell close to 8%.

Stocks also came under pressure on Middle East worries. Mixed messages have emerged recently out of negotiations to end the war, which has upset global markets and causedย oilย and gasoline prices to spike.
