US Stocks Climb for Third Day; Treasuries Rally: Markets Wrap

US stocks ended Tuesday’s session higher, with traders reloading wagers on an interest-rate cut next month while the latest AI advances drove Big Tech valuations.

The S&P 500 rose 0.9% after swinging between modest gains and losses earlier. The Nasdaq 100, after declining as much as 1.3%, wrapped up the day 0.6% higher. Economic data out of the US on Tuesday further cemented bets that the Federal Reserve will lower rates in December. That optimism had pushed stocks higher even on Monday.
