US stocks finish September higher


The S&P 500 ended up 0.4%, another record closing high. The Nasdaq 100 advanced 0.3%, while the Russell 2000 gained 0.2%. Both the S&P 500 and Nasdaq 100 ended the month up more than 2% and scored a winning quarter, too.

The stock rally during the last minutes of trading recouped earlier losses in the session. Major indices dipped in early afternoon amid Jerome Powell’s address at the National Association for Business Economics, where the Federal Reserve Chair said that the central bank was unlikely to keep cutting rates aggressively, as it did with a 50 basis point cut two weeks ago, unless the economy underperforms their expectations. 

US bonds slid. Yields on the policy-sensitive two-year Treasury note ticked higher by nearly 8 basis points. 10-year treasury yields also moved up.

Most S&P sector ETFs advanced as well. Materials was down the most by 0.6%, while real estate, the biggest gainer of the day, finished up 0.9%.

CVS rose 2.4% on Monday, after the Wall Street Journal reported that hedge fund Glenview Capital Management planned to meet with the executives at the company to propose ways that could improve its operations. Solventum Corporation, a spinoff of 3M health care, and Intuitive Surgical, a health care equipment company, were also among the best S&P 500 performers of the day.

Joby’s UAE reported certification delay stokes fears that air taxis may be further off than thought, sending eVTOL stocks down

Commercial air taxi service may be on a slower path than investors previously thought.

Shares of Joby Aviation fell more than 9% on Monday morning amid a report from The National that the company’s UAE certification will be completed by the third quarter of next year. That’s a significant delay from Joby’s own projected timeline in February, when it said it planned to carry passengers in Dubai in “late 2025 or early 2026.”

Rival Archer Aviation, which also recently suffered a hit to its UAE certification timeline, fell more than 9%. Joby and Archer each are expected to report their earnings results later this week.

Also potentially causing some investor pullback is the planned IPO of Beta Technologies on Tuesday. Beta, a manufacturer of electric aircraft, received a $300 million investment from GE Aerospace in September.

Micron jumps on report of surging memory chip prices

Micron, the US memory chip specialist, is up more than 4% in early trading Monday after a report that Samsung Electronics was temporarily pausing new pricing on contracts for the latest version of ubiquitous short-term computer memory: Dynamic Random Access Memory, or DRAM. The chip giant wants to see where the market settles after a recent spike in spot prices for memory chips driven by the AI boom.

DRAM and memory chips of all sorts have pricing power because of how much demand is outpacing supply. Last week, South Korean memory chip behemoth SK Hynix said it had already “sold out” all of its 2026 production.

Such signs of ongoing AI-related demand for IT hardware also gave a lift to other data storage device makers, such as Seagate Technology Holdings and Western Digital. The duopoly dominate the hard disk drive market, and have ridden a boom in demand for the affordable data storage devices to gains of more than 200% in 2025.
