Week 37 stocks review: CPI, oil and Oracle’s AI numbers raised the bar for September rates

The shortened U.S. trading week of Sept. 7-13, 2026 ended with lower equity benchmarks even after a Friday rebound, as investors weighed sticky inflation, surging oil prices and a fresh read on AI spending from Oracle. The S&P 500 fell 0.8% for the week, the Dow Jones Industrial Average lost 1.6%, and the Nasdaq Composite slipped 0.7%, with the S&P 500 closing at 7,656.98. Oracle’s fiscal first-quarter report stood out as the clearest company-level AI signal of the week: revenue rose 30% to $19.35 billion, cloud revenue climbed 62% to $11.6 billion, and cloud infrastructure revenue jumped 121% to $7.4 billion. Still, that strength did not offset a market repricing driven by August U.S. PPI and CPI data, crude oil moving above $100 a barrel, and sizeable equity fund outflows. Pressure was not limited to the U.S. South Korea’s KOSPI fell below 7,000 on Sept. 11, closing at 6,909.91 after a 1.76% drop, while Hong Kong equities also finished the week lower near 24,806. In mainland China, August CPI rose 0.8% year over year and PPI increased 3.8%, though the report pointed to energy-driven price pressure rather than a clearly verified recovery in household demand. Markets now turn to the Sept. 15-16 Federal Open Market Committee meeting, follow-up moves by other central banks, and whether Oracle’s AI demand signal can spread without another jump in yields or oil.
