US stocks surged on Wednesday following the Democrats' decisive victory in the midterm elections. The Dow Jones Industrial Average jumped 1,240 points, or 2.4%, marking its best day since April. The S&P 500 and Nasdaq Composite each rose 1.4%. Investors welcomed the clarity of the election results, which suggested a divided government would limit extreme policy shifts and reduce market volatility.
The VIX, a measure of market volatility, dropped 16%. Analysts noted that a Democratic-controlled Congress would likely constrain President Donald Trump's legislative agenda, particularly on taxes and spending. George Saravelos, global head of FX research at Deutsche Bank, observed that the election outcome should act as a brake on extreme policy outcomes.
US government bonds strengthened as expectations of reduced government borrowing and spending eased concerns. The dollar weakened against major currencies. Meanwhile, investors scrutinized the implications for data centers, critical to the AI sector, which saw mixed reactions. Shares of semiconductor chipmakers and AI infrastructure stocks fell, with Nvidia (NVDA) dropping 2% and an AI ETF declining 10%.
Tesla (TSLA) and SpaceX (SPCX) shares each fell about 4%, reflecting uncertainty over Elon Musk's future relationship with Texas following Democratic wins in the state. Elsewhere, CVS Health (CVS) shares plummeted 12% after announcing a corporate split.
