U.S. equities ended the week with modest gains, but Friday made the market’s central tension unmistakable: resilient AI-linked earnings are meeting a Federal Reserve still focused on inflation. The S&P 500, Nasdaq Composite, and Dow Jones Industrial Average all advanced, even as trading turned cautious after Chairman Kevin Warsh reiterated that policy could require further restraint if price pressures do not move convincingly toward target.
Week in Review
The S&P 500 gained 0.49% for the week to 7,711.76, the Nasdaq Composite rose 0.85% to 26,402.42, and the Dow added 0.53% to 53,559.99. The advance reflected confidence in earnings resilience despite elevated policy rates. The Nasdaq led as investors returned to the AI infrastructure theme, while the Dow’s gain showed support beyond the largest growth shares.
Thursday delivered the upside move. Nvidia’s outlook revived confidence in advanced-computing demand, lifting the Nasdaq 1.57% and the S&P 500 0.72%. Friday offered the counterpoint: Warsh said the Fed would have “more work to do” without confidence that inflation was moving toward 2%. The S&P 500 fell 0.25%, the Nasdaq dropped 0.52%, and the Dow slipped 0.02%, though all three held weekly gains.
The week was constructive but uneven. Investors rewarded companies that validated AI demand or raised outlooks, yet adjusted rate expectations. Energy weakness, subdued consumer sentiment, and higher short-term yields reinforced the value of watching breadth and macro data alongside index returns.
Top Stories of the Week
Nvidia renewed the AI demand narrative
Nvidia was the week’s key equity catalyst. Its shares jumped 8.7% Thursday after a robust forecast reinforced expectations for continued AI-infrastructure investment. The semiconductor index gained 2.3%, and the S&P 500 Information Technology sector rose 3.4%, the day’s best sector result. The report suggested that the AI capital-spending cycle still has earnings support despite its substantial funding needs.
Software results broadened the earnings read-through
The signal was not limited to chips. Salesforce climbed 22.6% Thursday after raising annual forecasts, while CrowdStrike gained 20.5% after lifting its revenue outlook. The results eased concern that generative AI would uniformly pressure established software businesses. Friday was more selective: Nvidia fell 4.6% and Marvell dropped 10.3%, while Alphabet rose 1.7% and Apple gained 1.6%. AI enthusiasm does not eliminate execution risk.
Jackson Hole restored the focus on rate risk
Warsh’s Jackson Hole keynote returned policy to center stage. He called the Fed’s 2% PCE inflation objective “firm” and “fixed,” said financial conditions did not appear restrictive, and kept the focus on prices. Futures implied a 57% probability of a September rate increase, versus 35% before the remarks, while the two-year Treasury yield rose to 4.34%, a one-month high.
Consumer and earnings dispersion remained evident
Friday’s individual moves illustrated the market’s selectivity. Gap surged nearly 13% after a new Old Navy chief executive was named and its annual profit outlook rose. Ulta Beauty fell 4.2% after comparable-sales growth slowed, and PayPal declined 12.7% after reports that a buyout pursuit ended. Investors rewarded tangible guidance and operational progress rather than granting a broad premium.
Investment implications: The week favored selectivity. Strong earnings preserve the AI-led growth case, but higher rate expectations raise the valuation hurdle for long-duration assets. Companies with credible outlooks, durable cash generation, and resilient balance sheets remain better positioned than firms dependent on rapidly lower rates.
Sector Performance Analysis
Technology was the visible leader. Through Thursday, the S&P 500 Information Technology sector was up 3.12% for the week, supported by Nvidia and the broader semiconductor complex. Utilities and financials were also positive through Thursday, rising 0.96% and 0.72%, respectively. Technology reflected renewed confidence in AI demand, while financials benefited from an environment in which higher-for-longer rates can support net interest income if credit conditions remain orderly.
Energy was the weakest major group through Thursday, down 2.54% as U.S. benchmark crude fell nearly 5% for the week to roughly $82.50 per barrel. Healthcare declined 1.76%, Consumer Discretionary fell 1.61%, and Consumer Staples slipped 1.04% over the same period. The pattern favored earnings visibility and AI infrastructure exposure while pressuring areas more sensitive to oil prices, consumer demand, or sector-specific earnings concerns.
Investment implications: The sector spread argues for diversification. Technology can remain influential, but Friday’s semiconductor pullback showed how rapidly concentration risk can emerge. Energy’s setback does not erase its strategic relevance, yet its near-term direction remains tied to crude prices and geopolitics. Portfolio balance should weigh earnings leadership against sensitivity to rates, commodities, and consumer demand.
Economic & Fed Developments
Inflation data supported the Fed’s caution. The Personal Consumption Expenditures price index rose 3.7% in the 12 months through July, above the 3.6% Reuters consensus estimate, while core PCE held at 3.3% year over year. Headline PCE increased 0.2% for the month after a 0.1% decline in June. The figures represent improvement from prior peaks, but not the sustained moderation policymakers seek before declaring that inflation is securely on a path to 2%.
Growth indicators remained firmer. Second-quarter real GDP growth was unrevised at a 1.5% annualized pace, while consumer-spending growth was revised up to 3.4%. Final sales to private domestic purchasers were revised to 4.2%, signaling continued underlying demand. The final University of Michigan consumer-sentiment reading of 51.7 nevertheless suggested that household confidence remains fragile. Persistent inflation alongside resilient activity leaves the September policy outlook unusually dependent on the next data releases.
Looking Ahead
Next week begins with a Labor Day closure and then moves quickly to new catalysts. Broadcom is scheduled to report fiscal third-quarter results on Wednesday, September 2, offering another important test of AI-related demand and of investors’ willingness to reward elevated technology expectations. The August Employment Situation report follows on Friday, September 4, at 8:30 a.m. Eastern Time. Markets will examine payroll growth, wage trends, and any change in labor-market stability.
The key question is whether the incoming data validate Warsh’s concern about stubborn inflation or reveal enough cooling to reduce the perceived probability of a September increase. The next consumer-price report follows the week after, ahead of the September 15–16 FOMC meeting. Market leadership may remain volatile: AI earnings can support technology, but rate-sensitive sectors and long-duration assets will react quickly to changes in the inflation or labor narrative. Earnings quality, valuation discipline, and diversification will remain essential as September begins.
