US stocks rally as traders welcome certainty after midterm elections

US stocks surged after Wall Street opened on Wednesday as President Donald Trump’s Republican Party suffered a series of defeats in the midterm elections.Top stock market indexes were given a boost in early trading as traders appeared to welcome the post-election certainty in the world’s biggest economy.The Dow Jones index had gained around 1,500 points, or 3%, a few hours into the day’s trading to reach its highest level in two months.The S&P 500 and Nasdaq indexes were also up by around 2%.Stronger trading across the pond helped deliver a boost to trading in the UK, with the FTSE 100 index surging by nearly 2% on Wednesday afternoon.At close, the blue-chip index was up around 190 points, or 1.8%, to 10,829.Experts said that US stocks typically jump following a midterm election, regardless of the outcome, because it provides investors with more certainty about the future.Rachel Winter, partner at Kilik & Co, said: “The market is experiencing a sizeable post-election bump, thanks to the removal of the pre-election uncertainty and the fact that Donald Trump has not contested the result.”She also pointed out that the result could have an impact on some tech stocks because of the potential for Democrats to push for more regulation to slow the pace of AI and data centre spending.Ms Winter said: “Several polls have indicated that Democratic voters are more likely to oppose data centres, and new Democratic senators have been elected following campaigns that focused on greater restrictions on data centre construction.“This is a potential problem for a variety of companies in this space, most notably CoreWeave, Oracle, SpaceX and Tesla.”Shares in Elon Musk’s Tesla and SpaceX were down by around 3% and 3.5% on Wednesday, respectively.CoreWeave was plunging by around 9%, while AI chipmaker Nvidia was down by about 2%.On the other hand, big tech stocks such as Amazon and Microsoft saw their share price jump by more than 6%.James Flintoft, head of investment solutions at AJ Bell, said: “Equity markets are likely to pay particular attention to how the Democrats intend to regulate the AI industry, as they have so far been less focused on seeing it as an ‘arms race’ with China.“Elon Musk reportedly spent 446 million US dollars (£331 million) backing Republicans in the midterms, with a large portion of the money going towards Republican Ken Paxton’s senatorial race in Texas, where he and his party lost.“The scale of the win for the Democrats could therefore result in a period of uncertainty for investors as they assess whether tech companies are set to face greater regulation.”
