Stocks close higher after whipsawing; oil surges

Yesterday's trading session saw major indices barely finish in the green as escalating US attacks against Iran sent oil prices soaring to their highest in over eight months. This surge propelled energy and defense stocks upward, while fuel-reliant travel assets dipped. Meanwhile, diverse earnings reports from companies like Nvidia, Hims & Hers, Core Scientific, and Archer Aviation caused significant, company-specific movements across various sectors.

What a day for the markets! Did global tensions just redraw the investing map, or were yesterday's sharp swings simply a response to a cascade of impactful earnings reports? While the S&P 500 (a stock market index representing 500 large U.S. companies) clung to modest gains, and the Nasdaq 100 (an index of 100 of the largest non-financial companies listed on the Nasdaq stock market) and Russell 2000 (a small-cap stock market index that makes up the smallest 2,000 stocks in the broader Russell 3000 Index) also edged higher, the underlying narrative was one of extreme volatility and clear winners and losers.

How Geopolitics & Earnings Whiplashed Markets

The S&P 500 managed a slight gain, with the Nasdaq 100 and Russell 2000 also closing in positive territory, despite a trading session marked by sharp fluctuations. This market resilience came even as the US launched attacks against Iran, stoking geopolitical fears. The volatility was largely driven by a combination of these rising international tensions and a flurry of corporate earnings announcements.

Oil's Ascent & Energy Sector Gains

Global oil prices surged dramatically, reaching their highest level in over eight months and even spiking as much as 13% at one point Sunday evening before paring gains. Concerns over the potential closure of the Strait of Hormuz, a critical chokepoint for oil shipments, fueled this rally. This directly translated into strong performance for energy shares.

Companies like Exxon Mobil, Chevron, Matador Resources, ConocoPhillips, and Occidental Petroleum all rose significantly, capitalizing on the jump in crude prices. Chevron's stock, for instance, surged toward a record high. Diesel prices also surged, outpacing crude and hitting their highest in two years, while natural gas futures in Europe jumped a whopping 41% as the region prepared for energy market fallout.

Defense Contractors Rally

The shift in focus towards defense spending amid the Iran conflict provided a strong tailwind for defense contractors. Palantir Technologies, an intelligence and defense contractor for the US and Israel, saw its shares pop. Similarly, established defense giants like Lockheed Martin, Northrop Grumman, and RTX all posted gains.

Related space industry plays also benefited. Satellite companies such as AST SpaceMobile, Planet Labs, and Firefly Aerospace, along with space infrastructure firm Intuitive Machines, experienced spikes as investor attention turned to the defense sector's potential growth.

Tech & Health Innovations Drive Specific Sectors

Beyond the geopolitical influences, specific corporate news and technological advancements continued to shape market movements for individual companies.

Nvidia and Optics Partnerships

Chip design powerhouse Nvidia gained after being named Morgan Stanley’s top pick in semiconductors. Further boosting its shares, the company announced an optics development partnership with Coherent and Lumentum, whose shares also surged on the news. POET Technologies, another optical communications company, likewise spiked.

Hims & Hers on Peptide Accessibility

Hims & Hers, a telehealth company, saw its stock soar following comments from Robert F. Kennedy Jr., identified as Health and Human Services Secretary, on the "Joe Rogan Experience" podcast. He expressed a desire to make about 14 peptides (short chains of amino acids that regulate various processes in the body) more accessible and allow for compounding. Such a shift could open up substantial new revenue opportunities for Hims & Hers, particularly given peptides are the active ingredients in popular GLP-1 medications for diabetes and weight loss.

Travel & Other Sectors Face Headwinds

While some sectors soared, others felt the pinch, particularly those sensitive to rising fuel costs and global supply chain disruptions.

Airlines and Cruises Dip

The surge in oil prices directly impacted the travel sector. Major airlines including United Airlines, Delta Air Lines, Alaska Airlines, American Airlines Group, Southwest Airlines, and JetBlue all dipped. Cruise line operators like Royal Caribbean, Carnival, and Norwegian Cruise Line also fell, facing both higher fuel costs and potential travel disruptions stemming from the Iran conflict.

Other Notable Movers: Berkshire, Sony, Nintendo

Beyond the direct impacts of geopolitical events, other companies experienced declines based on their own specific challenges. Sony and Nintendo shares dipped amid fears of increased global shipping costs. Berkshire Hathaway fell after its operating earnings dropped 30% year-on-year, with its insurance division showing particular weakness.

Company-Specific Earnings Impact

A series of individual earnings reports also triggered significant after-hours trading movements, demonstrating how micro-level performance can influence investor sentiment.

Core Scientific's Q4 Miss & Accounting Error

Core Scientific, a bitcoin miner that has pivoted to data centers, cratered in postmarket trading. The company reported significantly lower-than-expected sales for the final three months of 2025, with revenues of $79.8 million against an estimate of $115 million. While adjusted net income was $216 million (surpassing a -$47.5 million estimate), its self-mining and high-performance computing hosting divisions missed sales targets. The company also disclosed an accounting error, overstating the value of property, plant, and equipment in previous results, though management stated these changes do not affect revenue, adjusted EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization – a measure of a company's operating performance), or net cash flows. Shareholders notably rejected an offer from CoreWeave to purchase the company in Q4.

Credo Technology's Mixed Outlook

Credo Technology Group saw its shares tumble by double digits in postmarket trading. Although its Q3 results were solid, with revenues of $407 million (slightly above the $406.4 million estimate) and adjusted earnings per share of $1.07 (beating the $0.92 estimate), its Q4 guidance disappointed. Management projected sales between $425 million and $435 million, with the midpoint modestly below Wall Street’s $430.5 million call.

Archer Aviation's Deeper Loss & Defense Focus

Air taxi maker Archer Aviation reported a deeper-than-expected Q4 loss of $0.26 per share, missing analyst estimates of a $0.24 loss per share. Shares fell 2.4% after-hours. Despite this, the company ended 2025 with $1.96 billion in cash and cash equivalents, up from $1.64 billion in Q3. Archer anticipates Q1 adjusted EBITDA between -$160 million and -$180 million, significantly wider than Wall Street's -$104.7 million expectation. The company is targeting its first passenger flights this year and, notably, saw its shares rise over 5% on Monday due to investor focus on its defense business, which CEO Adam Goldstein considers "front and center" for the next decade.

Plug Power's Revenue Beat

Hydrogen fuel cell company Plug Power soared in postmarket trading after reporting strong fourth-quarter sales that outweighed substantial losses on its bottom line. The company's revenues reached $225.22 million, surpassing the $217.26 million estimate. Although it reported adjusted earnings per share of -$0.06 (beating the -$0.10 estimate), "various net charges" of $763 million caused other earnings metrics to look worse. Management reaffirmed its goal of achieving positive EBITDAS (EBITDA plus stock-based compensation) by 2026.
