Big U.S. Stocks Hit New High as Borrowing Costs Dip

America’s 500 biggest-company stock basket rose about 0.7% early Tuesday, Oct. 6, 2026, to pass 7,830 during the day, the Wall Street Journal reported. Reuters said the record came as interest rates on government loans fell from multi-year highs, which can mean cheaper mortgages and loans and make stocks look more valuable.
