On Wall Street, the Dow Jones Industrial Average reached a new record high, buoyed by strong gains in UnitedHealth shares following a significant buy by Warren Buffett. Investor sentiment remains positive amid speculations about potential rate cuts from the Federal Reserve, contributing to a generally optimistic atmosphere in the market. Despite slight declines in the S&P 500 and Nasdaq, the overall trend points towards a record-setting week for the markets. Analysts note that the surge in UnitedHealth has played a crucial role in pushing the Dow upward, highlighting the strength of blue-chip stocks even as technology shares face headwinds.
