U.S. stock index futures rose on Tuesday as voters headed to the polls in a closely contested election, with both Donald Trump and Kamala Harris expressing confidence in victory. Despite a tight race, betting odds favored Trump, leading to heightened market speculation. Investors are anticipating a potential interest-rate cut by the Federal Reserve on Thursday, which contributed to a slight easing of Treasury yields. The VIX, a measure of market volatility, indicated increased uncertainty, though it remained below levels seen in the lead-up to the 2020 election. Stocks linked to Trump’s potential success saw mixed trading results, while Nvidia and Sherwin-Williams gained on their addition to the Dow. Overall, the election outcome could lead to volatile trading as the final results may take days to determine.
