August began where July struggled to end: with conviction — and a Dow record to prove it. A weekend of de-escalation in the Middle East lit the fuse, and Wall Street ran with it.
The Dow Jones Industrial Average surged 693.38 points, or 1.32%, to a record close of 53,178.41, while the S&P 500 climbed 1.48% to 7,600.50 — within about 0.3% of its own all-time high. The Nasdaq Composite jumped 2.13% to 25,913.90, its best first-day-of-month performance since October 2022 and part of a three-session surge that has lifted the index more than 6%. The rally was broad, with eight of eleven S&P 500 sectors higher and the equal-weight index up 1%, but it was the megacaps that supplied the muscle.
The trigger was geopolitical relief. Over the weekend, President Trump called off planned strikes against Iran and said negotiations to reopen the Strait of Hormuz would proceed — and while Tehran disputed that any talks were formally scheduled, the direction of travel was enough. Oil tumbled roughly 5%, Treasury yields retreated from multi-year highs, and both stocks and bonds rallied together in a textbook risk-on session.

Oil’s Plunge Powers the Everything Rally
The single most important number of the day wasn’t in the equity market — it was in the oil pits. Crude settled down about 5%, reaching a three-week low, after the weekend’s de-escalation signals drained the war premium that had been driving energy prices and, with them, inflation fears.
The chain reaction was clean and powerful. Lower oil eased the inflation anxiety that had gripped the bond market all of last week, allowing Treasury yields to fall 4–7 basis points across the curve and pulling the 30-year back from the 19-year high it had touched days earlier. Falling yields, in turn, removed the single biggest headwind that had been capping the equity market’s advance. For a market that spent the previous week fretting over bond vigilantes and 5.2% long-term yields, the reversal was a release valve — the geopolitical premium bleeding out of oil did more to lift stocks than any single earnings report could.
A Dow Record, Led by the Megacaps
Amazon was the emblem of the day. After surging 15% on Friday’s blowout AWS results, the stock added another 4.6% on Monday to close at a record high — and in doing so, crossed $3 trillion in market capitalization for the first time, becoming just the fifth company in history to reach that milestone. The move validated Friday’s report and extended the cloud-earnings momentum that has carried the megacap complex since Microsoft’s blowout the prior week.
The rest of the Magnificent Seven joined the party. Meta surged 6%, Alphabet and Microsoft each climbed roughly 5%, and Nvidia popped nearly 3%. Communication services was the top-performing sector, up more than 4% on the strength of Meta and Alphabet. Notably, this leg of the rally has been led by the “old guard” megacaps rather than semiconductors — the Mag-7 added a record amount of market value over the three-day stretch even as the chip names, fresh off their worst month since 2008, took a back seat. Oracle (+9%) and Boeing (+8%) rounded out a session where the gains were as broad as they were forceful.
Manufacturing Roars to a Four-Year High
The macro backdrop reinforced the bullish mood. The ISM Manufacturing PMI jumped to 55.6 in July, up 2.3 points from June and well above the 54.0 consensus — the fastest pace of factory expansion in over four years and the highest reading since May 2022. It marked the seventh consecutive month of expansion, with the details as strong as the headline: production surged to 58.5, new export orders and backlogs each rose 4.5 points, and employment climbed to 52.8, entering expansion for the first time in 33 months. Encouragingly for the inflation picture, the prices index eased to 71.1, down 1.9 points from June.
The strength was global. Eurozone output hit a four-and-a-half-year high and Japan’s manufacturing PMI leaped to a twelve-year high — a synchronized pickup that, as Reuters noted, reflects how the AI capex boom is keeping the world’s manufacturers busy. There was one asterisk: the competing S&P Global manufacturing PMI held near a three-month low, a divergence worth watching, but on the day the market focused on the ISM’s unambiguous strength.
Notably, some of Thursday’s biggest winners gave back ground. Micron, SK Hynix, and SanDisk — which had exploded higher on the collapse of hedge fund Situational Awareness — pulled back on Friday as traders took profits after the violent one-day rebound. The semiconductor index’s flat close masked that rotation: cloud-leveraged names up, the previous day’s short-squeeze winners consolidating.
Earnings Scorecard and the Fed
The earnings season has been quietly excellent beneath the volatility. Of the 307 S&P 500 companies that had reported through Friday, 86% beat earnings-per-share estimates and 68% topped revenue expectations, with 15% missing on the top line — a genuinely strong showing that has helped underpin the rebound.
The week ahead is packed: 95 technology companies with market caps above $1 billion are scheduled to report, and Tuesday brings a marquee event — SpaceX’s first quarterly results since going public in June. The stock has traded below its $135 issue price for nearly three weeks, making the report a critical test of the market’s patience with the newest megacap. Palantir reports Monday evening, with AMD, SanDisk, and Western Digital also on the calendar — the latter three offering the next real read on AI-hardware demand after the chip sector’s brutal July.
On monetary policy, the tone softened. While several Fed officials voiced inflation concerns last week, New York Fed President John Williams struck a more optimistic note, saying he expects inflation pressures to ease gradually — while adding that the Fed stands ready to act if they don’t. His comments, paired with the retreat in oil and yields, helped temper the rate-hike anxiety that had weighed on the market.
Bottom Line
Monday was a sharp about-face from the month that preceded it. The forces that tormented the market in late July — surging oil, spiking long-term yields, and doubt over whether AI spending would pay off — all reversed at once. Oil plunged on Middle East de-escalation, yields fell in response, and the cloud-earnings momentum from Microsoft, Amazon, and Alphabet carried the megacaps to a record Dow close and Amazon’s historic $3 trillion milestone.
The setup into the rest of the week is constructive but not without tests. A four-year high in manufacturing, an 86% earnings-beat rate, and softening Fed rhetoric give the bulls real fundamental support. But oil has already ticked back up in Tuesday’s early trading, Iran has disputed the very talks that sparked the rally, and a wave of tech earnings — headlined by SpaceX’s public debut as a reporting company and AMD’s read on chip demand — will test whether this three-day surge is the start of a new leg higher or a relief rally running ahead of itself.
