Nasdaq hits fresh high on its 12th straight day of gains as investors surge into tech stocks, driven by fading AI disruption fears and a fragile Middle East cease-fire. The S&P 500 rose 0.3%, the Dow gained 0.2%, and the tech-heavy Nasdaq composite added 0.4%, marking its longest winning streak since 2009. Nvidia, AMD, and Broadcom led semiconductor gains, with the PHLX index climbing 1% for its 12th consecutive session. Energy stocks also surged, benefiting from elevated oil prices post-conflict.
