The technology sector is experiencing a significant rally, with the XLK ETF up over 1.5%, driven by positive sentiment surrounding artificial intelligence and anticipation of strong earnings from key players. Investor optimism is buoyed by upbeat analyst revisions for Meta Platforms ahead of its quarterly report and NVIDIA's announcements of expanded AI infrastructure partnerships. The broader tech-heavy Nasdaq is also seeing gains, partly fueled by better-than-expected profits from SpaceX, which has lifted sentiment across the AI-linked technology landscape.
