The Nasdaq Composite gained 0.45% to 27,244.28, led by Micron Technology and other AI-linked shares, while the S&P 500 was essentially flat and the Dow fell 0.36%.[9] Investors focused on the reception of Meta Platforms’ new transactional AI assistant even as oil traded near $100 and the 10-year Treasury yield hovered around 4.94%.[9]
