NextFin News - The U.S. stock market finished the session with a steady-to-positive tone, led by technology and communication services, while energy and materials lagged. The S&P 500 closed at 7,798.99, up 0.65%; the Nasdaq rose 0.81% to 26,803.03; and the Dow Jones gained 0.13% to 53,839.99. Trading remained constructive but selective, with investors favoring growth and AI-linked names while keeping a close watch on rates and inflation.

Among sectors, communication services was the strongest performer, with XLC up 2.07%, followed by real estate at 1.42%, consumer staples at 1.08%, and technology at 0.98%. The weakest areas were materials, with XLB down 0.53%, and healthcare, which slipped 0.04%. The pattern points to continued rotation into large-cap growth and defensive sectors, while cyclicals and commodity-linked groups remain mixed.

Top large-cap movers were concentrated in the mega-cap tech cohort. Tesla advanced 3.80% to $339.96 on volume of 34.04 million shares, adding roughly $13.43 billion in market value. Meta rose 2.78% to $594.97, adding about $15.16 trillion in reported market-cap units based on the feed. Apple climbed 1.00% to $305.26 on 38.51 million shares; Microsoft gained 0.90% to $496.88; Nvidia rose 0.54% to $225.30; and Alphabet added 0.82% to $346.36. Amazon was the main laggard in the group, down 0.80% to $265.13.

News flow tied the tape to earnings strength and a still-firm tech backdrop. Market coverage pointed to a broader earnings season in which S&P 500 companies have posted a high rate of positive EPS and revenue surprises, with FactSet citing 86% positive EPS surprises and 77% positive revenue surprises among companies reporting so far. That backdrop helped sustain demand for major growth stocks even as investors remained selective ahead of more tech results.

On the macro front, the inflation backdrop was mixed but not disruptive. Recent BLS data showed CPI up 0.1% in July 2026, while June PPI stood at 5.5% year over year and core inflation at 2.6%. Labor data were softer, with payrolls down 23,000 in July and unemployment at 4.1%. GDP was not newly reported in the fetched feed, but the combination of cooler inflation and softer labor readings supports the market's current focus on the policy path rather than immediate tightening pressure.

Federal Reserve messaging remained the key policy overhang. Recent FOMC coverage indicated that the fed funds target range was left unchanged at 3.50% to 3.75%, with officials emphasizing still-elevated inflation and solid economic activity. That has kept rate-cut hopes in check while also limiting downside pressure on equities, as the market continues to view policy as restrictive but not destabilizing. Trade and geopolitical headlines remained in the background, with ongoing U.S.-China and tariff-related concerns reinforcing a cautious stance toward globally exposed sectors.
