U.S. semiconductor stocks sold off after Intel unveiled a $15 billion common stock issuance plan, pulling the Philadelphia Semiconductor Index down 2.94% on the 10th, well beyond the moves in the main U.S. benchmarks. The S&P 500 fell 0.06%, the Nasdaq Composite slipped 0.32%, and the Dow Jones Industrial Average edged down 0.11%. Intel dropped 4.06% as investors focused on dilution risk from the company's first large-scale new share offering since going public, even as it said the funds would support artificial intelligence demand and its foundry (semiconductor contract manufacturing) business. Intel has raised this year's capital expenditure target from $18 billion to more than $20 billion and plans to expand investment further by 2027. The pressure spread across the sector, with Nvidia down 2.86%, Micron Technology off 1.89%, and SK Hynix's American Depositary Receipts (U.S.-traded share certificates) falling 1.90% to $135.29 before a muted 0.03% after-hours gain. Sentiment was also weighed by Middle East tensions after uncertainty grew over a U.S.-Iran deal to open the Strait of Hormuz and U.S. President Donald Trump formally demanded war-related reparations from Iran, sending WTI crude up 5.1% to $82.13 and Brent up 5.0% to $87.72. In South Korea's pre-market trade at 8:10 a.m. on the 11th, Samsung Electronics fell 1.7% to ₩226,000 and SK Hynix dropped 1.7% to ₩1.4 million, while the MSCI South Korea ETF lost 1.79%. Han Ji-young of Kiwoom Securities said the U.S.-Iran friction looked more like noise that enabled profit-taking than a threat to the broader market trend, but added that South Korea's market could rotate by sector as higher oil prices and interest rates trigger short-term selling in small and mid-cap shares.
