What happened
Solar stocks jumped on Wednesday, with First Solar (FSLR) and Sunrun (RUN) up about 8% and Plug Power (PLUG) up 10.6%, after Democrats won Congress, raising hopes federal clean-energy support will last. Democrats won both the House and the Senate in Tuesday's midterm elections. Investors think they will push back against the Trump administration's efforts to cut clean-energy support. The size of the gains changed during the day, and the stocks are still far below where they began the year: First Solar is down about 22% and Sunrun about 49% in 2026.
Why it matters
Solar stocks such as First Solar and Sunrun depend heavily on government tax breaks (tax credits), so who controls Congress changes how much these companies can expect to earn. A Democratic Congress could make it harder to cut those tax breaks further, though the White House is still run by the Trump administration. Investors also moved money away from AI data-center stocks, which fell the same day.
