Nova is trading 7.5% down at $346.24 after a broad semiconductor selloff tied to renewed calls from AI leaders to slow advanced-model development.
- Reuters reported that AI-heavy stocks and chipmakers weakened as investors worried about the pace of future AI infrastructure spending.
- The move appears sector-driven rather than company-specific: SOXX is down 5.54%, with no fresh Nova announcement, earnings surprise, or guidance change identified for September 14, 2026.
- The decline is occurring despite Nova’s September 11 close of $371.81.
