China's Alibaba has unveiled new plans for its AI model and new chip technologies, including what it claims is China's most powerful AI chip. This launch comes as U.S. AI leaders call for a slowdown in AI development over safety concerns. On Tuesday, at its annual conference in Hangzhou, Alibaba introduced the Zhenwu V900 AI chip, which it says triples the performance of its predecessor. The company also plans to train a new AI model with up to 10 trillion parameters, one of the measures of its capability. Analysts believe these advancements, announced just ahead of Chinese President Xi Jinping's meeting with U.S. President Donald Trump, could give China more leverage in U.S.-China talks.

Wall Street climbed to the edge of its all-time high, and stocks rallied worldwide after oil prices and yields in the bond market surrendered their market-rattling gains from last week. The S&P 500 jumped 1.5% Monday and pulled within 0.4% of its record. The Dow Jones Industrial Average added 0.7%, and the Nasdaq composite climbed 2.3% as chip stocks led the way. Stocks benefited from a drop for Brent oil back toward $100 per barrel, while the 10-year Treasury yield fell to 4.95%. The easing pressure helped indexes rise more than 1% from Germany to Hong Kong to South Korea.

AI stocks slid worldwide after leaders of the industry warned a slowdown is needed for the safety of humanity. Another climb in oil prices, meanwhile, briefly sent the yield on the 10-year Treasury to 5% on Monday for the first time since 2023. Despite all the downers, gains for many stocks outside AI helped limit Wall Street’s losses. The S&P 500 fell 0.5%. The Dow Jones Industrial Average dipped 0.3%, and the Nasdaq composite lost 0.6%. Brent crude's price settled at $105.68 per barrel after nearing $110 in the morning. The afternoon's retracement for oil prices pull the 10-year yield back to 4.98%.

Apple on Wednesday unveiled its latest generation of iPhones, including a widely anticipated foldable version called Duo. The company’s new CEO, John Ternus, who took over from Tim Cook on Sept. 1, introduced the latest lineup at the Steve Jobs Theater. After cycling through other updates to the iPhone, the Apple Watch and AirPods along with artificial intelligence advances, Ternus told the audience that “actually there is one more thing,” in a nod to the trademark phrase from Jobs that Jobs himself borrowed from the 1970s detective show “Columbo.” Called Duo, the phone has the “largest display ever on an iPhone, yet fits into your pocket,” Ternus said.

U.S. stocks fell in their return to trading from a three-day weekend after the latest fighting in the war with Iran pushed oil prices higher. The S&P 500 sank 0.6% Tuesday. The Dow Jones Industrial Average dropped 1.2%, and the Nasdaq composite slipped 0.3%. They felt pressure after the cost for a barrel of Brent briefly neared $99.50. More expensive oil has worsened worries about inflation and is giving extra heft to a couple of reports on inflation that are coming later this week. They will be the final updates the Federal Reserve hears on inflation before its meeting on interest rates next week.

Global shares are mixed, with benchmarks in Tokyo and Seoul leading gains thanks to buying of computer chipmakers. Benchmarks fell in early Monday trading in Germany and Britain, while being little changed in France. Brent crude oil inched closer to $100 a barrel as the U.S. military denied Iran had struck an uncrewed American military vessel in the Strait of Hormuz, which remains effectively closed.

Stocks fell on Wall Street and Treasury yields rose after a surprisingly strong report on the job market appeared to increase chances that the U.S. central bank could raise interest rates later this month. The S&P 500 lost 0.4% Friday. The Dow Jones Industrial Average fell 0.5%, and the Nasdaq composite gave back 0.3%. The government reported that U.S. employers added 162,000 jobs to their payrolls last month, far more than expected. That could give the Federal Reserve leeway to raise its benchmark short-term interest rate to fight inflation. The yield on the 2-year Treasury climbed to 4.37%.

Stocks rose on Wall Street as bond yields eased further and a rally in big technology companies helped the market recoup its losses from earlier in the week.

Nvidia rose 1.8% after the giant chip company said it would buy the artificial intelligence platform Hugging Face for $13 billion. Oil prices, which rose sharply earlier this week, closed little changed. Treasury yields fell in the bond market.
