World shares were mostly lower and South Korea’s benchmark dropped more than 5% on Friday after sharp declines for some big artificial intelligence-related stocks in the U.S.

U.S. futures were also trading mixed. The future for the S&P 500 lost 0.5%, while that for the Dow Jones Industrial Average edged 0.1% higher.

The sell-offs led investors in Asia to dump AI-related shares.

South Korea's Kospi sank 5.5% to 8,160.59. The index has roughly doubled in the past year, lifted by gains for big tech companies like SK Hynix, which lost 9.9%, and Samsung Electronics, which shed 6.4%.

Japan's Nikkei 225 slipped 1.3% to 66,588.12, with technology shares leading the decline, even as official data showed that Japan’s real wages rose for the fourth straight month. Chip equipment maker Tokyo Electron's shares fell 6.6%.


Hong Kong’s Hang Seng declined 1.2% to 24,961.95, while the Shanghai Composite index lost 0.7% to 4,027.74.

Australia’s S&P/ASX 200 fell 0.7% to 8,625.10.

Taiwan’s Taiex gave up 1.3%, while India’s Sensex was down 0.3%.

Oil prices continued to fall. Brent crude, the international standard, gave up 0.8% to $94.23 per barrel. It was approximately $70 per barrel before the war began in late February.

Benchmark U.S. crude dropped 1.1% to $92.04 a barrel.

On Thursday, the benchmark S&P 500 climbed 0.4% and the Dow Jones Industrial Average gained 1.7% to a record. The tech-heavy Nasdaq composite edged 0.1% lower.
