United Microelectronics is trading 8.8% down at $22.55 as the semiconductor sector faces pressure from valuation and profit-taking concerns.
- The decline follows a sharp pre-market drop, tracking a 3.09% move lower in the SOXX ETF.
- No company-specific catalyst was identified, with the selloff appearing to be a sector-led move driven by broader risk-off sentiment outweighing recent strength in Taiwan-linked chip names.
