TSMC is trading 3.86% up at $47.92 on September 4, 2026, following a broad semiconductor rally rather than a new company-specific announcement.
- The sector move is supported by Nvidia’s announced $12.9 billion acquisition of AI platform Hugging Face, renewing enthusiasm for AI infrastructure and chip demand.
- Stronger U.S. jobs data and higher Treasury yields are being outweighed by semiconductor-sector momentum.
