Dow Soars 1,112 Points as Democrats Seize Both Chambers of Congress

The Dow Jones Industrial Average climbed 1,112 points on Wednesday, marking a 2.1% gain as of 10 a.m. Eastern time. The surge pushed the index toward its strongest single-day performance in three months. The S&P 500 rose 1.8% during the same session, while the Nasdaq composite advanced 2.4%. The rally followed the midterm elections, in which President Donald Trump's party lost its sole control of Washington.

Wall Street strategists had previously advised investors to focus on corporate earnings rather than political outcomes. Brian Jacobsen, chief economic strategist at Annex Wealth Management, stated that earnings trump elections. Prices for stocks depend more on company profits and interest rates than on which party holds power in Congress. However, the market appeared to favor the new political configuration. Democrats are set to control both the Senate and the House of Representatives. This split control of Washington is generally preferred by investors because it reduces the risk of transformative economic changes.

Sector-specific reactions were mixed. Solar-power companies led the gains, with First Solar jumping 11.1% and Enphase Energy climbing 11.6%. Investors viewed Democratic control of Congress as a positive signal for the green energy industry. Conversely, Trump Media & Technology Group dropped 9.5%. The stock had already lost 55.1% for the year before Wednesday's session. Elon Musk’s companies also fell, with Tesla down 3.6% and SpaceX down 3%. Musk, a former top Trump adviser, is a possible target for investigations by the new Democratic-led Congress.

The artificial intelligence sector faced pressure. Nvidia slipped 0.5% after earlier falling as much as 2.8%. CoreWeave, which rents out access to AI chips, fell 6.8%. Investors expressed concern that Democratic victories in Texas could slow the buildout of new AI data centers. Advanced Micro Devices bucked the trend, rising 3.4% after reporting quarterly profits that exceeded analyst expectations.

In the bond market, Treasury yields eased. The yield on the 10-year Treasury fell to 4.92% from 4.95% late Tuesday. Yields had reached their highest levels in decades during the summer due to concerns over U.S. government debt and inflation. A Democratic-controlled Congress may provide a check against further spending increases or tax cuts that would widen the deficit.

Global markets largely mirrored the U.S. rally. Stock indexes in Paris, Shanghai, and London each rose 2.2% or 1.8%. Japan’s Nikkei 225 was an outlier, falling 1.4%. Oil prices declined, with Brent crude dropping 2.9% to $100.63. The price of the most actively traded Brent contract has fluctuated between $70 and $120 per barrel since the war with Iran began.

Carsten Brzeski, global chief of macro at ING Bank, offered two forecasts for the coming months. He noted that Trump is not a lame duck but an angry duck who might restart tensions over tariffs and NATO spending. Alternatively, Trump could become a tame duck, slowing disruptive efforts and focusing on ending major wars to secure a Nobel Peace Prize.
