A strong jobs report pressured broad indexes while semiconductor strength, software weakness, and supply-chain risks split the tape.
Good afternoon. This is the CAMS Midday Market Check for Friday, September 4, 2026. This edition uses a late-session snapshot captured just before 4 p.m. Eastern.
The strong August jobs report set the tone. Payrolls increased by 162,000, well above expectations. Unemployment held at 4.1 percent, wages rose three tenths of one percent for the month, and June and July were revised higher by a combined 55,000 jobs. The report strengthened expectations that the Federal Reserve could raise rates at its September meeting. Next week's inflation reports now carry even more weight.
By 3:58 p.m., the S&P 500 was down about four tenths of one percent, the Nasdaq Composite was down roughly three tenths, and the Dow was lower by about one half of one percent. A delayed Russell 2000 quote was slightly positive. That small-cap resilience kept the tape from looking uniformly defensive, even as the main large-cap indexes remained under pressure.
Breadth was close to balanced around midday. Reuters reported slightly more decliners than advancers on the New York Stock Exchange, while Nasdaq breadth was nearly even. The late sector map was narrower. Technology and industrials were the only positive major sectors. Consumer discretionary, communication services, and health care led the declines.
The headline indexes hid a sharp split inside technology. The semiconductor fund SMH gained 2.7 percent on above-average volume, while the software fund IGV fell 2.2 percent. Marvell led the chip gains. AMD, Super Micro, Intel, and Applied Materials each rose more than 4 percent, while Microsoft and CrowdStrike were lower. This was a rotation toward chips and hardware, not a broad technology rally.
Company news reinforced that divide. AMD introduced a prototype Threadripper Halo Station for 2027, combining a workstation processor with Instinct-class accelerators and a very large memory configuration. Pricing, shipment volume, customer commitments, and financial impact were not disclosed. Nvidia said RTX Spark Windows computers from Acer, Lenovo, and other manufacturers are scheduled to arrive in October. Again, near-term unit and revenue effects remain unquantified.
Elsewhere, earnings reactions were severe. Lululemon fell about 17 percent after reporting lower revenue and comparable sales and reducing its full-year outlook. Trading volume was more than five times its recent average. Zscaler fell about 5 percent even after quarterly revenue grew 25 percent. Its volume was more than twice its recent average.
Cross-assets reflected the shift in rate expectations after the jobs report. The ten-year Treasury yield was near 4.78 percent, about two basis points above Thursday's close, and the dollar index was up roughly one quarter of one percent. December gold futures fell 1.3 percent. The VIX remained low near 14.5, even though it was modestly higher on the day. West Texas Intermediate crude was almost flat near 91 dollars and 36 cents, but oil remained sharply higher for the week.
Reuters also reported that some Chinese rare-earth suppliers had declined U.S.-bound shipments after a Chinese countermeasure complicated minerals diligence. China's Ministry of Commerce confirmed the underlying countermeasure. The number of suppliers and aggregate volume were not known. Chip shares were still among the day's strongest groups despite the supply report. The identified evidence does not establish why.
President Trump added another uncertainty after the jobs report by saying he could stop trade with some nations if the Federal Reserve did not cut rates. The identified reporting did not establish a formal directive, a country list, an implementation timetable, or a published legal mechanism. It remains a statement with potentially large consequences, not an implemented policy.
Oil and diesel prices remain another concern. Oil's weekly rise and a reported nominal record near 5 dollars and 85 cents per gallon for average U.S. diesel keep freight and inflation pressure in view. The duration of Gulf disruption and the ultimate effect on global energy supply are still unknown.
The broad market was modestly lower, midday breadth was close to even, semiconductors were strong, and software and consumer discretionary shares lagged. Yields rose after the payroll surprise. Next week's inflation data and any concrete rare-earth or trade measures will test whether chip leadership can persist.
