U.S. stocks showed mixed results on Tuesday, with the S&P 500 gaining 0.1% to close at 6,616.85 points, while the Dow Jones Industrial Average fell by 85.42 points to 46,584.46. The Nasdaq composite also rose by 0.1%, reaching 22,017.85 points. The market's fluctuations were largely influenced by increasing uncertainty surrounding the ongoing conflict with Iran, which has led to volatility in oil prices and consumer sentiment. The average price of gasoline in the U.S. surged to $4.14 per gallon, significantly impacting companies with high fuel costs, such as Norwegian Cruise Line Holdings and United Airlines, which dropped 3.3% and 1.8%, respectively. Conversely, stocks of health insurers like UnitedHealth Group and Humana saw significant gains, rising 9.4% and 7.9% respectively, following an announcement of a 2.48% increase in Medicare Advantage payments expected for 2027. The bond market also reacted, with the yield on the 10-year Treasury falling to 4.30%, although still higher than pre-war levels, affecting mortgage rates and borrowing costs for households and businesses.
