Weekly Wrap: Energy Leads, Payrolls Rise, as Large-Cap Indexes Grind Higher

Markets delivered a mixed but resilient tape during the week, but beneath the surface, leadership was narrow.
Large-cap indexes edged higher while small caps and several cyclical groups lagged.
This week, the Dow Jones Industrial Average ($DJI) gained 0.24%, the S&P 500 (SPX) rose 0.47%, and the Nasdaq-100 (NDX) added 0.17%. The Russell 2000 (RUT) declined 0.14%, and the S&P 500 equal-weight index (SPXEW) slipped 0.3%, showing that index resilience depended heavily on a handful of large-cap winners.
Today’s job report might be a swing factor. Nonfarm payrolls rose a seasonally adjusted 162,000 for the month, and unemployment held steady at 4.1%, the Bureau of Labor Statistics reported Friday. Economists expected August payrolls to rise by roughly 55,000, with unemployment ticking up to 4.2% from July’s 4.1%. The hotter than expected report pushed yields a bit higher with the 10-Year near 4.78% and the expectations for a rate hike up to about 60%, according to the CME FedWatch tool.
Sector Performance Showed the Clearest Rotation
The top three S&P 500 sectors for the week were energy, up 3.27%, health care, up 1.22%, and information technology, up 0.86%. Energy led as renewed U.S.-Iran tensions pushed crude prices sharply higher. WTI crude (/CL) is up over 8%, and Brent crude (/BZ) is up more than 7% over the same stretch, as the conflict revived concerns over potential supply disruptions tied to the Strait of Hormuz and kept an inflation-risk premium in energy markets.
The weakest sectors week to date were industrials (down 1.51%), materials (down 1.16%), and consumer discretionary (down 0.87%). AI-linked large-cap strength helped the headline indexes, but semiconductors, software, cyclicals, and smaller companies traded unevenly. See Cybersecurity Surges as AI Threats Drive Market Rotation
All Eyes on the FOMC Rate Decision
Economic data kept the Federal Reserve debate alive. ISM Manufacturing slowed to 54.6 in August from 55.6 in July, which is still expansionary but showing some loss of momentum. ISM Services improved to 55.4, with new orders at 60.9, but the price index component climbed to 72.6, and employment remained contractionary at 47.8. That combination pointed to firm demand, sticky input costs, and soft hiring which is exactly the kind of mix that complicates Fed policy.
Labor-market data also supported a resilient view, but also gradually losing momentum. JOLTS showed job openings were little changed at roughly 7.3 million in July, while hires and separations were also little changed. Initial jobless claims rose slightly to 206,000, suggesting layoffs remain low even as job creation slows. The data does not point to recession, but it also does not offer a clean signal that the Fed can ignore inflation risk.
Fed Governor Christopher Waller helped lift sentiment Thursday by saying he would lean toward holding rates steady in September if upcoming inflation data continue to cool, though he left the door open to a hike if inflation comes in hot. After his remarks, market-implied September hike odds eased, while the 10-year Treasury yield pulled back toward roughly 4.75% after recently touching higher levels. Still, with oil elevated and service-sector prices sticky, investors remain cautious about the Fed’s next move. See Thursday's Closing Bell: U.S. Stocks Up Alongside Nvidia (NVDA) Hugging Face M&A
Earnings Were a Mixed Bag
Dell Technologies (DELL) rallied after record revenue and stronger AI-server guidance, supported by continued demand for AI-optimized infrastructure. Broadcom (AVGO) beat estimates and posted strong AI semiconductor growth, but shares fell as guidance failed to satisfy elevated expectations. Palo Alto Networks (PANW) also beat estimates, helped by strength in next-generation security products, but the stock dropped as investors focused on valuation, organic growth, and conservative guidance.
