Dow Slides Over 250 Points as Treasury Yields Rebound; Eli Lilly Pops on Obesity-Drug Breakthrough; Small Caps Buck the Sell-Off

NEW YORK, May 21, 2026 — American consumers got their clearest signal yet this earnings season that the nation’s largest retailer is bracing for a tougher spending environment. Walmart Inc. shares tumbled more than 6% on Thursday after the company paired in-line first-quarter results with cautious annual guidance, dragging the broader market lower as oil prices ripped past $100 a barrel on fresh tensions with Iran and Treasury yields climbed once again.

The S&P 500 declined 0.45%, the Dow Jones Industrial Average lost 0.48%, and the Nasdaq Composite fell 0.50%. The Dow shed roughly 252 points in afternoon trading, with Walmart (-6.43%), Salesforce (-4.27%) and Sherwin-Williams (-2.20%) leading the losses, while IBM (+3.69%), Honeywell International (+0.99%) and Chevron (+0.97%) held the index from a steeper decline. The Russell 2000 bucked the trend with a 2.56% gain, signaling rotation into domestically focused small caps less exposed to oil prices and rate risk.

Crude jumped on a Reuters report that Iran’s Supreme Leader Ayatollah Ali Khamenei issued a directive that the country’s near-weapons-grade enriched uranium must remain inside Iran — a development that complicates U.S.-Iran de-escalation efforts and revived inflation concerns just as Treasury yields rebounded. West Texas Intermediate crude rose $2.86 to $101.14 a barrel intraday, with Brent climbing toward $107. The move reversed two sessions of softening energy prices built on hopes for a diplomatic resolution. The 10-year Treasury yield sits near a one-year high, and gold slipped about $20 to roughly $4,512. The VIX ticked up to 17.62.

Walmart’s Caution Signals a Frugal American Consumer

Walmart (NYSE: WMT) posted first-quarter revenue of $177.8 billion, up 7.3% year-over-year and slightly above the $176.7 billion Wall Street consensus. Non-GAAP earnings per share of $0.66 met estimates. The problem was the forward look: management guided next-quarter revenue to $185.4 billion, roughly 0.5% below analyst expectations, and reaffirmed cautious annual guidance citing rising fuel costs, tariff pressures and what the company has flagged as more frugal consumer behavior. The sell-off came despite 26% e-commerce growth and 37% growth in advertising revenue — underlying strengths that ordinarily would have been celebrated. Walmart shares remain up roughly 19% year-to-date, but Thursday’s drop wiped out a portion of that gain in a single session and gave investors a real-time read on how America’s biggest retailer sees U.S. consumer spending heading into the summer.

Deere Reports Into a Tariff Headwind

Deere & Company (NYSE: DE) reported second-quarter fiscal 2026 results today against Wall Street expectations of $5.74 EPS on $11.50 billion in revenue, with the agricultural-equipment maker absorbing $1.2 billion in pretax tariff costs this fiscal year. New Chief Financial Officer Brent Norwood, who stepped into the role May 1 after more than two decades inside the company, took his first earnings call as investors pressed on margin trajectory and dealer-inventory levels. Deere shares had entered the print down roughly 15% from their all-time high.

Eli Lilly Pops on Obesity Drug Breakthrough

Eli Lilly (NYSE: LLY) shares rose 1.05% after the drugmaker said its next-generation obesity drug retatrutide cleared a crucial late-stage trial. In the highest-dose cohort, patients lost an average of 28.3% of body weight — roughly 70.3 pounds over 80 weeks — compared with 2.2% for placebo, according to CNBC’s coverage of the results. The data brings Lilly meaningfully closer to seeking approval for the weekly injection, which works differently from existing GLP-1 therapies from Lilly and Novo Nordisk and may offer stronger efficacy. The development carries direct consumer implications across U.S. healthcare costs and the broader obesity-treatment category, which is reshaping pharmaceutical and grocery economics simultaneously.

Analyst Calls and Sector Moves

Earlier this week, Home Depot (NYSE: HD) reported better-than-expected first-quarter earnings. Morgan Stanley analyst Simeon Gutman, who carries an overweight rating, told clients “The housing backdrop appears static and HD continues to execute well in a relatively ‘growthless’ environment,”  arguing the stock is not pricing in a housing recovery and that any “glimmer of inflection” in home-improvement end markets should be a positive. The session followed Wednesday’s broad rally on Nvidia (NASDAQ: NVDA) earnings, in which the AI chip leader posted April-quarter revenue topping $81 billion and a July-quarter outlook of $91 billion that fell shy of the most bullish analyst expectations. Nvidia declined to forecast any China sales despite CEO Jensen Huang’s recent Beijing visit. Nvidia shares hovered near the flatline Thursday as energy and yields took over the narrative.

What’s Next

Investors now turn to additional earnings tonight from Take-Two Interactive (TTWO), Workday (WDAY), Zoom Communications (ZM), Ross Stores (ROST), Ralph Lauren (RL) and Deckers Outdoor (DECK). With WTI above $100, the 10-year Treasury yield near one-year highs, and the Iran uranium standoff unresolved, the market enters Friday with two converging pressures — energy-led inflation and rate-driven valuation compression — that have, for now, overtaken the AI-earnings tailwind that defined the prior session.
