United Microelectronics is trading at $14.43, down -10.12%, mainly amid a broader semiconductor selloff linked to post-election concerns about AI regulation and data-center construction.
- October sales rose 18.33% year over year to NT$25.20 billion; January–October sales increased 16.33%.
- Recent earnings-related weakness may also weigh: a report cited an EPS miss and cautious fourth-quarter guidance. No stronger company-specific negative catalyst surfaced.
