Stock Market Today: Stocks Slide as Iran Tensions Stir Markets, Oil Jumps on Hormuz Shutdown Fears

U.S. stocks started the week on shaky ground this Monday as renewed geopolitical tensions shook investor confidence and sent risk assets diving across the board. The Nasdaq Composite led declines, dropping around 1%, while the S&P 500 fell roughly 0.6% and the Dow Jones Industrial Average slipped about 0.3% as traders reacted to escalating conflict tied to Iran.
The sell-off follows a volatile weekend that saw a breakdown in ceasefire expectations and a sudden halt in traffic through the Strait of Hormuz, one of the world’s most critical oil chokepoints. The move has injected fresh uncertainty into markets that had recently been hovering near record highs, forcing investors to reassess both inflation risks and the broader economic outlook.
Market Movers:
- Compass Pathways (CMPS) +34% – Shares surged after new federal support for psychedelic research signaled a potential breakthrough moment for mental health treatments, with investors betting on faster regulatory pathways. The policy shift is seen as a long-term catalyst for commercialization, lifting sentiment across the sector.
- Nektar Therapeutics (NKTR) +17% – The stock jumped following positive late-stage clinical data showing improved efficacy in treating alopecia areata, with strong patient response rates over time. Investors also welcomed the therapy’s clean safety profile, which strengthens its case for advancement into pivotal trials.
- TopBuild (BLD) +16% – Shares rallied after agreeing to a roughly $17 billion acquisition by QXO in a cash-and-stock deal that includes a notable premium for shareholders. The transaction highlights continued consolidation in the building materials space and expectations for long-term synergies.
- USA Rare Earth (USAR) +14% – The company gained after announcing a strategic acquisition that secures access to critical rare earth materials outside of Asia. The deal positions the firm as a key player in the global supply chain for essential components used in electronics and defense.
- Sidus Space (SIDU) -18% – Shares dropped sharply after the company priced a new stock offering, raising concerns about dilution among existing shareholders. The capital raise, while supportive of operations, weighed on near-term sentiment.
- Fermi (FRMI) -13% – The stock fell following a major leadership shake-up, including the departure of its CEO and CFO. The uncertainty around executive stability raised questions about the company’s strategic direction and execution.
- AST SpaceMobile (ASTS) -8% – Shares declined after a satellite launch failed to reach its intended orbit, marking a setback in the company’s rollout plans. While insured, the incident introduces near-term operational risk and delays.
- Eli Lilly (LLY) -2% – The stock edged lower after announcing a multibillion-dollar acquisition aimed at expanding its oncology pipeline. Investors appeared cautious on the deal’s size and potential near-term financial impact despite its strategic rationale.
Oil Shock Ripples Through Markets
Energy markets took center stage as oil prices surged following the disruption in the Strait of Hormuz. U.S. crude climbed more than 5% to trade above $87 per barrel, while Brent crude pushed past $95, reflecting mounting concerns over global supply constraints. The sharp move in oil is reigniting inflation fears just as investors had begun to grow more comfortable with moderating price pressures. Higher energy costs could quickly filter through to transportation, manufacturing, and consumer goods, complicating the outlook for both central banks and corporate margins.
Big Week Ahead for Earnings
Markets are also bracing for a heavy slate of corporate earnings that could further test investor sentiment. Major names across tech, industrials, and travel are set to report, with particular focus on whether companies can maintain growth in the face of rising input costs and geopolitical uncertainty. Tesla, Intel, and United Airlines are among the high-profile companies reporting this week, offering insight into everything from consumer demand to supply chain resilience. With valuations stretched near recent highs, results will need to justify continued optimism.
Wall Street vs. Main Street Divide Widens
Even as equities hover near record levels, a growing disconnect between market performance and consumer sentiment is raising eyebrows. Surveys show consumers remain deeply pessimistic about the economy, even as stocks have staged a powerful rebound. This divergence suggests underlying fragility in the economic backdrop, where strong asset prices may not fully reflect real-world pressures like inflation, borrowing costs, and wage stagnation.
Looking Ahead
The path forward for markets will likely hinge on two key factors: geopolitics and earnings. Any signs of de-escalation in the Middle East could quickly stabilize oil prices and restore risk appetite, while further disruptions could deepen volatility. At the same time, this week’s earnings will serve as a reality check for a market that has rallied hard into uncertainty. If corporate results and guidance hold up, stocks may find a floor—but if cracks begin to show, the combination of geopolitical risk and economic pressure could trigger a more sustained pullback.
