ON Semiconductor Stock (NASDAQ: ON) Week Ahead Outlook: Nasdaq-100 Exit, Buybacks, and GaN Catalysts to Watch (Dec. 22–26, 2025)
Date: Sunday, December 21, 2025 ON Semiconductor Corporation (onsemi) heads into a holiday-shortened trading week with two unusual forces likely to dominate price action: (1) index-driven flows tied to ON’s removal from the Nasdaq-100, and (2) a steady drumbeat of strategic announcements aimed at power semiconductors for AI infrastructure, EVs, and industrial energy systems. As of the latest close, ON stock finished at $55.21. StockAnalysisWhile fundamentals matter over time, the coming week could be shaped by liquidity (thin holiday trading), rebalancing mechanics, and headline sensitivity—especially around onsemi’s expanding presence in gallium nitride (GaN) and silicon carbide (SiC) power devices.
