Summary · why it matters

The S&P 500 slipped 0.2% into negative territory by midday Monday, erasing early gains driven by a sharp drop in oil prices, as a broad semiconductor sell-off weighed on the market. Brent crude fell about 6% to around $86.40 per barrel after the U.S. and Iran agreed to pause military strikes, easing inflation concerns and pushing Treasury yields lower. However, news that China's ChangXin Memory Technologies went public in Shanghai with a valuation near $490 billion and that a Shanghai firm began mass-producing DUV lithography machines triggered a rout in chip stocks, with ASML dropping more than 7%, Nvidia falling 4.3%, and Micron Technology losing roughly 5%. The Dow Jones Industrial Average held a 0.2% gain, while the Nasdaq Composite was off 0.5%. Mega-cap software and services stocks provided some support, with Microsoft up 2.3%, Alphabet adding 2.8%, and Apple gaining 1.3%.
