Core Market Move – July 31, 2026
On July 31, 2026 U.S. equity indexes closed higher after Amazon.com (AMZN) posted its strongest quarterly revenue growth in more than four years and reported a 37% year-on-year increase in Amazon Web Services (AWS) revenue. The stock jumped between 13% and 15%, lifting the S&P 500 by 0.7% to 7,489.72 and the Nasdaq Composite by about 1% to 25,373.85. Apple (AAPL) fell 7%–9% after warning that component shortages would curb near-term growth, pulling the technology-heavy S&P 500 technology index down 0.5%.
Background & Context
Throughout July, investors worried that massive AI-related capital expenditures by “big-tech” firms might outpace demand, a sentiment that had depressed AI-heavy stocks earlier in the month. The PHLX chip index remained more than 20% below its June 22 record high, reflecting lingering doubts about AI spending. Microsoft’s cloud earnings the previous week had already begun to ease some of those concerns.
Data & Statistics
- Amazon: Q2 revenue up 37% YoY; AWS backlog $496 billion; capex forecast $220 billion for 2026.
- Apple: Fiscal Q3 revenue $109.4 billion (+16% YoY); diluted EPS $2.02 (+29% YoY); revenue guidance 9%–11% (below 12% consensus).
- Market breadth: Decliners outnumbered advancers 1.3-to-1 on the S&P 500; semiconductor index stayed more than 16.7% lower for July.
- Yield environment: 10-year Treasury yield rose to 4.73%, with a 69% probability of a Fed rate hike in September.
Official Statements & Responses
Amazon’s CEO Andy Jassy said AWS growth is “booming” and that the unit’s revenue expansion was the fastest since 2021. Apple’s chief executive Tim Cook attributed the softened guidance to “very significant” component shortages, noting the firm cannot secure enough microchips for its iPhone, Mac and iPad lines.
Conflicting Reports & Gaps
Sources differ on the exact magnitude of Amazon’s share surge on July 31: Reuters cited a 15% jump, CNBC reported a 14% increase, and TS2 recorded a 13.4% rise. Apple’s guidance range (9%–11% versus a consensus of 12%) appears consistently reported, but the underlying assumptions for the forecast were not disclosed.
Verbatim Quotes
- “There were worries that Amazon's spending was just moonshot spending, that it's irresponsible spending, and (CEO) Andy Jassy just put those fears to bed,” — Jake Dollarhide, CEO of Longbow Asset Management
- “The market went from throwing AI stocks overboard to fighting for the remaining seats before most traders had finished writing the obituary,” — Stephen Innes, SPI Asset Management
- “Both the earnings as well as the sentiment are kind of coming back a bit after the really overexaggerated move in the earlier part of the week,” — Fabien Yip, IG analyst
Why It Matters
The divergent performance of Amazon and Apple shows investors rewarding concrete AI-related revenue growth while penalizing firms facing supply constraints. Market confidence in AI spending now hinges on visible earnings traction rather than projected capital outlays.
What’s Next
Analysts expect the Federal Reserve to decide on a September rate hike, with market pricing indicating a 69% probability. In the AI arena, Amazon’s backlog and AWS growth suggest continued demand, while Apple’s ability to secure chip capacity will be a key factor for its upcoming quarterly performance.
