US stocks: US market rallies, Dow ends with record on US-Iran deal, oil price slide

US markets surged with the Dow hitting a record close as a US-Iran deal framework drove crude oil futures down 4.9% to their lowest since March, easing inflation fears and reviving risk appetite. The S&P 500 gained 1.67% to 7,555.26, Nasdaq jumped 3.07% to 26,686.64, and the Dow rose 0.96% to 51,684.88, with technology, airline, and cruise stocks rallying while energy shares fell. Investors are now eyeing the Fed's policy meeting on Wednesday, pricing in a 42% probability of a 25-bps rate hike by year-end amid easing oil-driven inflation concerns.
