The S&P 500 closed above 6,500 for the first time on 28 August 2025, ending the session near 6,500 after touching an intraday peak of about 6,502. The move set a fresh all-time high for the benchmark equity gauge. The index has rebounded roughly 33 percent from its April 2025 trough of 4,982, marking its fifth 100-point milestone this year. It has climbed from about 3,500 five years ago and 2,100 a decade earlier, underscoring the length and strength of the current bull market. Thursday’s advance followed stronger-than-expected quarterly results from Nvidia, which added momentum to a rally driven by enthusiasm for artificial-intelligence hardware and resilient U.S. corporate profits. Market strategists said the milestone highlights investors’ confidence but warned that valuations are becoming increasingly stretched.
