ChipMOS Technologies is trading 7.8% down at $64.78 as traders take profits following a sharp multi-day rally to multi-year highs.
- The decline reflects sector-wide semiconductor weakness after TSMC’s higher capital-spending plans raised cost and valuation concerns, prompting broad selling across chip names.
- There is no new company-specific news today; the drop is primarily driven by profit-taking and a wider risk-off mood regarding AI and semiconductor stocks.
