The Dow's fresh record close leans heavily on a geopolitical accident: oil's 6% one-day plunge after Trump paused an Iran strike in favor of talks. That drop in crude did real work today, easing inflation worries and giving the broader market room to run — but it is also reversible the moment negotiations stall, at which point today's rally loses its foundation. Amazon's push past a $3 trillion market cap is a different story. AWS revenue beat consensus by roughly four points, offering concrete evidence that AI infrastructure spending is starting to convert into real cash flow rather than just promises. Still, the combined 2026 capex plans of the four largest hyperscalers — about $725 billion, up 77% year over year — remain a genuine overhang. The market is currently willing to trust the ROI story, but a single disappointing quarter could trigger a serious valuation reset. Tellingly, the Fear & Greed Index still sits at 45, in 'Fear' territory, even as the Dow prints new highs — a sign that investors themselves aren't fully convinced this rally has legs.
📊 Top Movers
🧭 Sector Performance
🇰🇷 Korean Investor Perspective
For Korean investors, the standout move is the currency. USD/KRW slid to the 1,420s, a recent low, meaning won-denominated returns for unhedged 'seohak-gaemi' (Korean retail investors in US stocks) trailed the headline index gains — the Nasdaq's 2%+ rally was partly offset by won strength. Popular ETFs like QQQ and SPY likely moved roughly in line with their underlying indexes, and interest may rise in Amazon (post-earnings beat) and Oracle (ongoing Gemini AI partnership tailwind). Notably, Micron (MU) — closely watched by Korean investors as a Samsung/SK Hynix memory-market peer — rose only modestly (+0.79%), suggesting today's rally was driven by single-stock catalysts (Oracle, Boeing, Amazon) rather than a broad memory-sector move.
📊 Market Overview
U.S. stocks kicked off August with a bang on Monday, August 3, 2026, as all three major indexes rallied sharply. The S&P 500 climbed 110.78 points (+1.48%) to close at 7,600.50, while the Nasdaq Composite surged 540.05 points (+2.13%) to 25,913.90. The Dow Jones Industrial Average jumped 693.38 points (+1.32%) to a record close of 53,178.41.
The immediate trigger for the rally was easing geopolitical risk. President Trump held off on a planned strike against Iran over the weekend and signaled a return to negotiations on Monday, instantly relieving oil-driven inflation fears that had weighed on markets. That macro relief combined with an Amazon earnings surprise to pull buying into Big Tech broadly, while standout single-stock catalysts at Oracle and Boeing added further fuel. Still, with much of the gain resting on a one-off oil-price drop, a degree of caution persisted beneath the surface.
🔑 Key Issues
1. US-Iran diplomacy resumes, oil plunges 6% After Trump paused planned military action against Iran and agreed to resume talks Monday, WTI crude fell $5.07 (-6%) to $79.60 a barrel. OPEC+ added to supply-side pressure by agreeing to raise output by roughly 188,000 barrels per day starting in September. The oil plunge eased reflation fears and lifted the broader market, but hit the energy sector directly (Chevron -1.85%, ConocoPhillips -1.10%).
2. Amazon crosses $3 trillion market cap for the first time Amazon shares jumped 4.58%, pushing the company's market capitalization above $3 trillion for the first time. AWS revenue came in at $42.2 billion, beating the $40.54 billion consensus, while total revenue of $200.61 billion topped the $196.47 billion Wall Street expected. Adjusted EPS of $1.97 beat the $1.82 estimate. The single-day market-cap gain of roughly $400 billion was Amazon's largest in 14 years, making it the fifth company — after Apple, Microsoft, Alphabet, and Nvidia — to join the $3 trillion club.
3. Oracle extends rally for a second day on Google Gemini partnership Oracle shares surged 9.22%, the day's top gainer, as investors continued to reward last week's expanded AI partnership with Google — a deal bringing Gemini models into Oracle's Fusion Applications, AI Agent Studio, and NetSuite enterprise software.
4. Boeing jumps 8% on a rare double upgrade from BNP Paribas Boeing rose 8.03% after BNP Paribas analyst Matthew Akers double-upgraded the stock straight from Underperform to Outperform, lifting his price target to $300 from $230. The move coincided with FAA certification of the 737 MAX 7 — nearly a decade in the making — and a surprise Q2 free-cash-flow beat ($631 million versus an expected $388 million burn).
5. ISM Manufacturing PMI hits a four-year high July's ISM Manufacturing PMI came in at 55.6, beating both the 54.0 consensus and June's 53.3 reading — the highest level since May 2022. New orders (56.7) and production (58.5) both remained firmly in expansion, marking a seventh straight month of manufacturing growth.

🚀 SPCX (SpaceX) Update
SpaceX (SPCX) closed at $114.53, up 5.68% from Friday's $108.37. The move appears driven less by a company-specific catalyst — no launch, contract, or regulatory news was identified — and more by the broad risk-on shift following the easing of Iran-related tensions, riding alongside the Amazon/Oracle-led growth-stock rally. No unusual volume spike or firm-specific event was confirmed; the gain reads as a beta move within a market-wide risk-on session.
⚠️ Investor Considerations
Much of today's rally rests on a reversible catalyst — easing Iran-related geopolitical risk. Should talks break down or new tensions emerge, oil could snap back quickly, unwinding today's gains. Separately, with the four largest Big Tech capex spenders (Amazon, Microsoft, Alphabet, Meta) set to spend a combined $725 billion in 2026, up 77% year over year, valuation pressure could resurface if evidence that AI spending is converting into revenue and cash flow — as Amazon just demonstrated — doesn't keep arriving. The Fear & Greed Index sitting at 45 ("Fear") even as the Dow hits a record high is itself a signal that caution persists beneath the market's surface.
👁 Tomorrow's Watch Points
- Caterpillar (CAT) earnings (Tuesday, before the open): Consensus calls for EPS of $6.20 (+31.4% YoY) on revenue of $19.2 billion (+15.7%). With Industrials the day's top-performing sector, a miss could trigger sector-wide give-back.
- Palantir (PLTR) earnings reaction: Reported after Monday's close, the market's reaction should directly shape early Nasdaq volatility Tuesday morning; given rich valuation, the size of any beat or miss versus consensus matters.
- Whether the S&P 500 holds 7,600: Watch whether the index extends its push to fresh records or gives back gains to profit-taking.
- Whether WTI rebounds off $79: Any headline risk around the Iran talks could send oil bouncing back, reviving inflation concerns alongside a potential energy-sector rebound.
- Pre-positioning for Wednesday's ISM Services PMI: Markets may spend the week testing whether the manufacturing surprise extends into the services reading.
