Tower Semiconductor is trading 12.68% down at $165.95 on October 30, 2026, amid a semiconductor selloff after Intel’s weaker-than-expected fourth-quarter forecast and warning of continued PC-market weakness. - Reuters reported Intel’s warning sparked a selloff in global chip stocks; concerns about Amazon’s AI spending added pressure. - Available reporting identified no company-specific announcement explaining the decline; the move is best attributed to sector weakness, not a confirmed Tower-specific catalyst.
