Wall Street rallies, Dow closes at record on Iran talks optimism

Bristol Myers Squibb BMY.N shares were little changed after a report of preliminary merger talks with AstraZeneca AZN.L. A deal could form one of the world's biggest drugmakers, worth nearly $400 billion. Hotel operator Marriott International MAR.O slumped after forecasting third-quarter profit below expectations. New York Federal Reserve President John Williams expressed optimism that inflation pressures would ease gradually. A report last week that U.S. Fed Chair Kevin Warsh raised the idea of scheduling fewer rate-setting meetings added to concerns about less clarity around the central bank. Markets are pricing in a 66.5% chance for a rate hike of at least 25 basis points at the Fed's September meeting, according to CME Fedwatch. Investors will receive several readings on the labor market this week, culminating with the government jobs report on Friday. Communication services .SPLRCL was the best performing of the 11 major S&P sectors, climbing more than 4% on gains from Meta Platforms META.O and Alphabet GOOGL.O. Energy .SPNY dropped more than 1% as the worst performer on the session. "Every day, everybody wakes up and looks at the price of a barrel of oil and the yield on the 10-year, and if that's going lower, the market's OK, and if it's going higher, the market's not good whatsoever," said Art Hogan, chief market strategist at B. Riley Wealth in Boston. "Typically earnings are a time that give us a chance to forget about disturbing macro influences, but this go around has not been one of those times." According to preliminary data, the S&P 500 .SPX gained 110.89 points, or 1.48%, to end at 7,600.61 points, while the Nasdaq Composite .IXIC gained 539.01 points, or 2.12%, to 25,912.86.

Other AI-linked companies reporting this week include Palantir PLTR.O, Advanced Micro Devices AMD.O as well as data storage companies SanDisk SNDK.O and Western Digital WDC.O. U.S. stocks kicked off August on a strong note to send the Dow Industrials to a closing record high, as signs of de-escalating U.S.-Iran tensions pulled down oil prices and Treasury yields in a busy week for earnings and economic data. Crude prices settled down about 5% after U.S. President Donald Trump said on Sunday that talks with Iran to reopen the Strait of Hormuz would take place on Monday, though Iran disputed that talks were planned. The drop in oil prices helped push U.S. Treasury yields lower, even as market participants continued to gauge the odds of a rate hike from the Federal Reserve should the Iran war continue for a prolonged period.
