Clean energy stocks rally as Democrats win Congress

Shares in wind and solar companies climbed across Asia, Europe and US premarket trading on Wednesday, November 4, after Democrats won control of both the Senate and the House in the US midterm elections. Investors are betting that a Democratic Congress will bring friendlier policy for an industry that has struggled under President Donald Trump's administration. Denmark's offshore wind developer Orsted Ørsted A/S led European gains, rising as much as 8.1%, while Vestas Wind Systems and SMA Solar Technology ↗ 0.00% also moved higher, Bloomberg reported.bloomberg.com

Democrats flipped at least seven Republican-held Senate seats, including in Texas, Ohio, Kansas and Maine, CNN projected. As of early Wednesday, Democrats were on track for at least 245 House seats and at least 54 Senate seats, according to CNBC.us.cnn.com+1

Gains spread from Seoul to New York

The rally started in Asia. South Korea's Hanwha Solutions closed sharply higher, and HD Hyundai Energy Solutions and OCI Holdings also rose, Investing.com reported. In Europe, Germany's Nordex ↗ 0.00%, Portugal's EDP Renovaveis and France's Voltalia gained as well.

Why investors are buying

Investors see a Democratic wave as good for the clean energy supply chain, including solar and batteries, and bad for traditional energy, according to Investing.com. The outlet added that renewables are also gaining from a rotation out of stocks tied to artificial intelligence. Before the vote, analysts told Reuters that a strong Democratic showing could keep federal support for clean energy in place. They named First Solar, Sunrun, Enphase and NextEra Energy ↘ 0.66% as likely beneficiaries.finance.yahoo.com+1

Defense stocks retreat

Defense contractors went the other way. Lockheed Martin ↘ 2.53%, Northrop Grumman ↘ 0.15% and RTX ↘ 3.10% each fell more than 2% in premarket trading, Dow Jones reported. In Europe, BAE Systems, Thales and Rheinmetall declined. Investors fear Democrats will put military spending under closer scrutiny, since Congress has not yet funded large replenishment contracts, according to Investing.com. Trump's proposed $1.5 trillion defense budget for fiscal 2027 has not been approved, and Jefferies analysts wrote that control of Congress will decide who has leverage over the final funding outcome, Dow Jones reported.sg.finance.yahoo.com+1
