Where they agree
- All three outlets report the S&P 500, Dow, and Nasdaq hit records or near-records Tuesday, with the Dow up roughly 900+ points and the S&P 500 up about 1.8-2%.
- They agree the rally was driven by Treasury Secretary Scott Bessent’s comments about a possible imminent deal with Iran to reopen the Strait of Hormuz, which pushed oil prices and bond yields down.
- All cite strong corporate earnings — especially Palantir’s 93% revenue jump and Caterpillar’s record $20 billion quarter — as a major second driver.
- All note S&P 500 companies are tracking toward roughly 50% earnings growth this quarter, the strongest since 2021.
- CBS News gives more weight to the JOLTS labor report as a third contributing factor and includes a caution that past Iran deal hopes have fallen through.
- CNBC structures its piece around five distinct catalysts and relies most heavily on strategist commentary about market psychology and possible future volatility.
- The Guardian emphasizes valuation context (stocks looking less “expensive” relative to profits) and details chip-stock gains and AI-linked demand for Caterpillar’s turbines more than the others.
- Outlets report slightly different exact figures for Caterpillar’s stock gain (5.6% vs. 6.5%) and the S&P 500’s percentage increase (1.8% vs. nearly 2%).
What happened on Tuesday
U.S. stocks surged to record highs on Tuesday, August 4, 2026, in one of the strongest single-day rallies of the year. The Dow Jones Industrial Average jumped about 907 points, or roughly 1.7%, marking its best day in nearly two months and building on a record set the day before. The S&P 500 climbed about 1.8% to 7,736, breaking past its previous all-time high from June 2. The Nasdaq Composite, powered by tech and chip stocks, gained 2.6%.
The rally had several drivers converging at once. Treasury Secretary Scott Bessent told CNBC’s “Squawk Box” that the U.S. and Iran were in talks and that a deal to reopen the Strait of Hormuz — a critical corridor for global oil shipments — could come within a day or two. That commentary sent Dow futures higher, pushed oil prices down sharply, and pulled bond yields lower. Brent crude sank 5.3% to $79.36 a barrel, a steep drop from the $72-to-$102 range it swung through in July amid uncertainty over whether tankers could keep moving through the Persian Gulf during the monthslong conflict with Iran. The 10-year Treasury yield fell to 4.62% from 4.70% on Monday, though it remains well above the roughly 3.97% level seen before the war began.
Corporate earnings gave the rally its other major leg. Palantir Technologies stock jumped nearly 30% after CEO Alex Karp described the AI company’s quarter as “otherworldly,” with revenue up 93% and the company raising its full-year 2026 revenue forecast. Caterpillar shares rose between 5.6% and 6.5% (reports vary slightly) after the equipment maker posted its first-ever quarter above $20 billion in sales and revenue, with CEO Joe Creed pointing to strong order rates, including rising demand for turbines that power AI data centers. Chipmakers also rallied, with Nvidia up 2.6%, Broadcom up 6.6% and Micron Technology up 7.6%. Coming into the week, S&P 500 companies were on pace for nearly 50% year-over-year earnings-per-share growth for the spring quarter, according to FactSet — the biggest jump since the pandemic-recovery spring of 2021.
A government report also played a supporting role: the Job Openings and Labor Turnover Survey (JOLTS) showed hiring holding up and layoffs at modest levels, easing fears the labor market was overheating or cooling too fast.
How the coverage differs
All three outlets tie the rally to the same two pillars — progress toward reopening the Strait of Hormuz and unexpectedly strong earnings — but they weight things differently. CNBC frames the story explicitly around “five reasons” and leans heavily on trader and strategist voices (Bespoke Investment Group’s Paul Hickey, Mariner’s Jeff Krumpelman, Blue Chip Daily’s Larry Tentarelli, Freedom Capital Markets’ Jay Woods) to explain market psychology and caution that Iran headlines could still swing sentiment either way. CBS News gives the JOLTS labor data more prominence as a third driver, quoting Vital Knowledge’s Adam Crisafulli tying the rally directly to Caterpillar and Palantir earnings, Bessent’s Hormuz remarks, and a JOLTS report that wasn’t as alarming as feared. CBS also adds a note of skepticism, recalling that past claims of an imminent Iran breakthrough — including from President Trump — have fallen through before. The Guardian focuses more on valuation context, citing Leuthold Group’s Phil Segner on how surging profits make stock prices look less expensive than before, and gives more specific detail on chip-stock movements and the AI-driven demand behind Caterpillar’s results.
The outlets also differ slightly on precise figures — CNBC and the Guardian describe the S&P 500 gain as “nearly 2%,” while CBS specifies 1.8% and a close of 7,736. Caterpillar’s stock gain is reported as 5.6% by the Guardian and 6.5% by CBS. None of these differences change the overall picture, but they reflect the usual variation in exact closing numbers across outlets reporting the same trading day.
Why this rally matters
The gains cap a volatile stretch tied to the war between the U.S./allies and Iran, which had roiled oil markets and stock prices since fighting broke out in late February. The Dow and S&P 500 are now up about 12% and 13% for the year, respectively, and the Nasdaq is up 14%, according to CBS, despite lingering worries about a possible AI-driven stock bubble. A genuine reopening of the Strait of Hormuz would matter well beyond Wall Street: lower oil prices generally ease inflation pressure and borrowing costs, which affects everything from mortgage rates to the financing costs companies face building AI data centers. But as CBS notes, similar hopes for a breakthrough have been raised and dashed before, meaning Tuesday’s rally reflects optimism about a deal that has not yet been finalized.
