First Solar is trading 4.1% up now at $198.85 as September 17, 2026’s broad risk-on rally lifts equities.
- The S&P 500 is up 1.09%, while the Nasdaq is up 1.59%.
- The move follows the prior session’s 5.57% decline after First Solar withdrew its USITC TOPCon complaint while retaining federal-court lawsuits against competitors.
- That patent decision remains an overhang rather than a clear catalyst for today’s rebound.
