July’s last session was a clean sweep. The Nasdaq rose 1% to 25,373.85, the S&P 500 added 0.7% to 7,489.72, and the Dow gained 276.97 points, 0.53%, to 52,485.03 — all of it into surging bond yields, and most of it powered by one stock. Amazon closed up 15% after AWS grew 36.7% to $42.2 billion, its fastest clip in 18 quarters, on total revenue of $200.6 billion against estimates near $196.5 billion. Amazon also raised its 2026 capital spending plan to roughly $220 billion, and the market said thank you.
Zoom out one notch and the picture inverts. For the month, the Dow rose 3.22% — its fourth straight winning month. The S&P 500 fell 0.72%. The Nasdaq dropped 2.38%. That S&P decline is the number with history attached: the index had not lost a July since 2014, an 11-year streak in what has been the market’s most reliable month. The streak died in the same week Big Tech posted some of its best earnings ever.
Friday was the whole month in miniature. On the winning side: Amazon +15%, Newell Brands +17.5%, Monolithic Power +11%, DexCom +11.2%. On the losing side: Apple fell 9.5% even after beating on revenue with iPhone sales up 22% — soft Services and China results plus the outlook did the damage. Reddit dropped 22.5% despite beating on both lines, punished for warning about volatile search-referral traffic in an AI-search world. GoDaddy lost 20.2% on underwhelming guidance and the same AI-disruption worry. Roblox collapsed 29% — its worst day on record — after missing on revenue and pulling full-year guidance. Coinbase fell double digits after its third straight quarterly loss. MasTec dropped 16%. The indexes were calm. Underneath them was a shooting war — the same violent single-name dispersion that moved Microsoft and Apple 7% to 15% in opposite directions earlier this week while the benchmark barely blinked.
Rotation, not retreat
Read the monthly scoreboard carefully: money did not leave the market in July. It moved. Out of crowded AI-adjacent tech — the Nasdaq’s 2.38% monthly loss — and into the older-economy, cash-flow-now names the Dow overweights, which is how the Dow wins a month by nearly four percentage points over the S&P. Even Friday’s hero trade fits the pattern: Amazon’s $220 billion capex plan is exactly the kind of spending that has been paying the unglamorous electrical suppliers like Eaton before it pays anyone else.
Our take: “The market” didn’t lose July — the Nasdaq did. When beating earnings gets you +15% and a cautious outlook gets you −20% to −29%, positioning is setting prices, not fundamentals. That is a regime where the index level tells you almost nothing and single-name risk is everything: own the spending (infrastructure, power, cloud capacity) rather than the story, and treat any stock priced for perfection as a coin flip on guidance day.
What to watch
- Where the $220 billion lands. Amazon’s raised capex follows Microsoft and Google — watch whether the picks-and-shovels names keep printing record quarters off it.
- AI-search contagion. Reddit and GoDaddy both got repriced on traffic anxiety in one session. Every business model built on search referrals now carries the same discount risk.
- August without the crutch. Yields are rising, July’s seasonal tailwind is gone, and the S&P just proved streaks end. The Dow’s four-month run is the next one the tape will test.
