Oil Craters as the U.S. and Iran Pause the Fighting — Apple Retakes the Crown From Nvidia Heading Into the Busiest Week of Earnings Season

A Quiet Surface Hides a Lot of Movement Underneath

U.S. and Iran Pause Military Strikes, Sending Oil Prices Tumbling

• The U.S. and Iran paused fighting Monday after two weeks of strikes, raising hopes that peace negotiations could restart. WTI crude tumbled roughly 7-8% to about $82-83 a barrel and Brent crude fell 4% to below $86 — the sharpest one-day drop of the conflict.
• The de-escalation calmed markets broadly: the CBOE Volatility Index (VIX) fell ▼ 4.5% to 17.74, reflecting reduced investor anxiety, while gold ticked up modestly to $4,081.37 an ounce as traders continued to hedge against a fragile truce.
• Cheaper fuel costs gave the biggest lift to industrial and travel-exposed names, helping push the Dow Jones Industrial Average up 262.83 points, or ▲ 0.51%, to 52,210.08 — the day's best-performing major index.
• The rally proved uneven elsewhere: the S&P 500 finished essentially flat at 7,413.18 (▲ 0.02%) and the Nasdaq Composite slipped ▼ 0.18% to 24,932.08 as chip-stock losses offset the broader relief.

Nvidia Slides on China Fears as Apple Reclaims the Market-Cap Crown

• Nvidia (NVDA) dropped ▼ 5.0% to $201.38 on renewed concerns about Chinese competition in AI chips, dragging the semiconductor sector lower alongside Intel (INTC) ▼ 7.9%, Coherent (COHR) ▼ 9.8%, and Lumentum (LITE) ▼ 8.5%.
• Apple (AAPL) rose to $336.22, lifting its market cap to roughly $4.94 trillion and pushing it back past Nvidia's $4.87 trillion — reclaiming the title of world's most valuable company ahead of its earnings report Thursday.
• SanDisk (SNDK) tumbled ▼ 10.8% on memory-market weakness, extending a month-long slide, while freight and logistics name C.H. Robinson Worldwide (CHRW) fell ▼ 9.2%.
• Software stocks rebounded broadly as investors rotated back into enterprise names, with ServiceNow among the session's standout gainers in the group.

Earnings Beats Fuel a Packaging, Energy-Services, and Data-Center Rally

• International Paper (IP) led S&P 500 gainers, up ▲ 11.2%, as analysts hiked price targets on packaging-pricing strength, followed closely by Smurfit WestRock (SW) ▲ 11.1% and Packaging Corporation of America (PKG) ▲ 8.8% as the containerboard sector rallied on reports of a price hike.
• SLB (SLB) jumped ▲ 11.0% after a strong second-quarter earnings beat, with the oilfield-services giant's CEO calling it the start of an upcycle in global oil investment — even as crude prices fell on the Iran de-escalation.
• Digital Realty Trust (DLR) climbed ▲ 11.0% after a big second-quarter beat and a raised 2026 outlook, underscoring continued demand for AI-driven data-center capacity.
• RTX Corp added roughly 2.6% on strong quarterly results, and Germany's SAP jumped about 7.4% after beating expectations, extending Monday's earnings-season gains into European tech.

Dow Outperforms as Oil's Slide Offsets a Choppy Session for Tech

• The Dow Jones Industrial Average led index gains, rising ▲ 0.51% to 52,210.08, while the S&P 500 edged ▲ 0.02% higher to 7,413.18 and the Nasdaq Composite slipped ▼ 0.18% to 24,932.08. The Russell 2000 outperformed all three, adding ▲ 0.61% to 2,948.03 as small caps extended their 2026 run.
• Monday's mixed session followed a rough week: the S&P 500 fell ▼ 0.6%, the Nasdaq dropped ▼ 2.1%, and the Dow slipped ▼ 0.4% for the week ended July 24, as tech capital-expenditure worries and a "Magnificent Seven" pullback weighed on sentiment.
• The 10-year Treasury yield eased to 4.65%, gold rose modestly to roughly $4,081.37 an ounce, and the VIX fell ▼ 4.5% to 17.74 as the Iran pause reduced near-term hedging demand.
• Bank of America analysts flagged a seasonal caution point, noting stocks "perform worst in the three months between August and October," citing elevated energy costs and bond yields as additional headwinds heading into the back half of the year.

What to Watch the Week of July 27

• The Federal Reserve announces its rate decision Wednesday, July 29 at 1:00 PM Central, with Chair Kevin Warsh's press conference to follow at 1:30 PM Central — markets widely expect the Fed to hold rates steady.
• Big Tech earnings dominate the week: Microsoft and Meta Platforms report Wednesday, followed by Apple and Amazon on Thursday — investors will scrutinize AI capital-expenditure guidance after Nvidia's slide and recent volatility tied to spending concerns.
• Coca-Cola, PayPal, and Visa report Tuesday, July 28, while Exxon Mobil and Chevron close out the week Friday with results that will show how the Iran de-escalation and lower crude prices are hitting energy-sector profits.
• Core and headline PCE inflation data for June arrive Thursday, July 30, alongside weekly jobless claims, offering an early read on whether price pressures are cooling enough to support future rate cuts.
• The fragile U.S.-Iran truce remains the key swing factor for oil. Any breakdown in the pause — or a breakthrough toward a lasting deal — could send crude sharply in either direction.
