U.S. stocks opened mixed Wednesday as elevated long-dated bond yields and oil prices near $95 per barrel stoked concerns about inflation and a possible Federal Reserve rate hike. The 10-year Treasury yield touched its highest level since November 2023. Technology stocks were little changed, with Dell Technologies surging 10% after reporting a standout quarter driven by record orders for its AI server business. Financials, healthcare and communication services gained, while energy and utilities declined. Hewlett Packard Enterprise, NIO, GitLab and AST SpaceMobile were among the stocks drawing attention from Yahoo Finance readers.
