Market Reaction: Democrats' Sweep Drives Sectors Apart

The stock market issued a sharp verdict on the November midterm results on Wednesday. Shares moved broadly after Democrats secured control of both the House and Senate, alongside key gubernatorial victories in Texas and Georgia. Traders quickly separated winners from losers across nearly every sector in response to the shift in political power.

Investors bet that the incoming Democratic Congress would act as a counterweight to President Donald Trump's agenda. That agenda has included tax cuts, tariffs, and policies that have contributed to higher inflation, such as the Iran war. Wells Fargo Investment Institute noted that Democratic control could slow the push for deregulation in financials, energy, and digital assets. The firm added that both parties still have incentives to compromise on data center locations and artificial intelligence generally.

Clean energy stocks emerged as some of the day's biggest winners. Traders expected Democrats to push back against the administration's rejection of clean energy policies. Nextpower jumped more than 11.2 percent, while Canadian Solar rallied 6.7 percent. Nextera Energy added 4.9 percent, First Solar climbed 4.6 percent, Plug Power gained 3.6 percent, and Sunrun rose 1.3 percent.

Healthcare names surged on optimism that spending cuts might slow or reverse. Investors also hoped for extended subsidies in Affordable Care Act plans. Centene led the group with a 12.6 percent gain. Universal Health Services rose 10.9 percent, HCA Healthcare gained 10.3 percent, Tenet Healthcare added 9.6 percent, Molina Healthcare climbed 8.9 percent, and Elevance Health rose 4.9 percent.

Elon Musk's companies took a hit after Democrats won the gubernatorial, Senate, and attorney general races in Texas. They also took control of the Texas House. Tesla shed 3.3 percent and SpaceX lost 3.8 percent. Musk spent at least $474 million backing Republican candidates in the midterms, including $224 million in Texas, where both companies are headquartered.

Defense contractors fell on concerns that Democrats could challenge military spending. Lockheed Martin tumbled 6.9 percent, Northrop Grumman sank 4.5 percent, and Howmet Aerospace fell 4.3 percent. The Trump administration has requested $1.5 trillion for national defense in fiscal 2027. It is also seeking an $87.6 billion supplemental appropriation for fiscal 2026, largely due to the Iran conflict. Drone stocks dropped sharply, with Kratos Defense down 12.3 percent and Red Cat down 10.4 percent.

Data center stocks moved lower amid worries about restrictions on AI infrastructure buildouts. CoreWeave slumped 9.9 percent, Iren dropped 11.2 percent, and Nebius fell 6.7 percent. Comfort Systems and Vistra lost 15.1 percent and 13.8 percent, respectively. Micron Technology fell 7 percent. Five of the Magnificent Seven rallied, with Microsoft jumping 6.7 percent and Apple rising 5.3 percent to touch an all-time high.

A consumer relief trade took hold as affordability shaped the election. Housing stocks Pulte, D.R. Horton, and Lennar gained roughly 7.2 percent, 8.1 percent, and 7.1 percent, respectively. Airlines climbed, with United Airlines up 8 percent and Delta Air Lines up 7.2 percent. Trump Media & Technology Group plunged 24.5 percent and hit a 52-week low.
