Markets Rattled as Geopolitical Tensions Flare: S&P 500 and Nasdaq Slide on Iran Conflict

Opening Bell: A Sea of Red Amid Global Uncertainty

The U.S. stock market opened sharply lower on Monday, March 2nd, 2026, as investors reacted to a dramatic escalation of geopolitical tensions in the Middle East over the weekend. Major market indexes saw significant downward pressure immediately following the opening bell. The S&P 500 (SPY) fell approximately 1.18%, trading near the 6,798 level, while the tech-heavy Nasdaq Composite (QQQ) led the decline with a 1.46% drop. The Dow Jones Industrial Average (DIA) was not spared, plunging over 500 points, or roughly 1.05%, in early trading.

The primary catalyst for this "risk-off" sentiment was the announcement of "Operation Epic Fury," a series of coordinated military strikes by the United States and Israel against targets in Iran. Reports confirming the death of Iran’s Supreme Leader, Ayatollah Ali Khamenei, sent shockwaves through global markets. With the Strait of Hormuz—a critical chokepoint for 20% of the world's oil supply—effectively closed, market participants are bracing for a prolonged period of volatility and potential inflationary pressure.

Geopolitical Shockwaves: Energy and Safe Havens Surge

As equities tumbled, commodities and safe-haven assets saw explosive gains. Brent crude oil surged as much as 13% in overnight trading before stabilizing at a gain of roughly 8%, trading near $82 per barrel. Gold (GLD) hit a historic milestone, catapulting past $5,300 per ounce as investors sought protection from the escalating conflict. In the bond market, the flight to safety pushed the 10-year Treasury yield down to 3.97%, dipping below the 4% mark for the first time in several weeks.

The sudden spike in energy prices has complicated the outlook for the Federal Reserve. Analysts warn that higher crude prices flow directly into transportation and manufacturing costs, potentially reigniting inflation just as the market was hoping for further rate cuts. This comes at a pivotal time for the central bank, as Kevin Warsh is currently pending Senate approval to replace Jerome Powell as Fed Chair in May.

Corporate News: Defense Gains While Tech Pivots

While the broader market struggled, the defense and energy sectors emerged as clear outliers. Defense contractors saw a surge in demand; Lockheed Martin (LMT) and Northrop Grumman (NOC) jumped between 3% and 7% in early trade, while RTX (RTX) also posted significant gains. Energy giants like Exxon Mobil (XOM) and Chevron (CVX) rose 3-5% on the back of soaring oil prices.

In the technology sector, Nvidia (NVDA) remained a focal point of high-volume trading. Despite reporting blowout Q4 results last week, the stock has faced pressure, trading down nearly 6% over the last few sessions due to concerns over AI spending sustainability. However, the company made headlines today by announcing a $2 billion investment in each of the optical networking firms Lumentum Holdings (LITE) and Coherent (COHR), causing shares of those two companies to "moon" in early trading.

Apple (AAPL) also drew attention as CEO Tim Cook teased a "big week ahead," with rumors circulating about a special event on Wednesday to unveil the iPhone 17e and updated MacBook models. Meanwhile, Microsoft (MSFT), Alphabet (GOOGL), and Meta Platforms (META) all traded lower as part of the broader tech retreat. Other notable movers included AMTD Digital (HKD), which surged 20% on strong revenue growth, and Leebang International (LBGJ), which crashed 24% following a subsidiary acquisition announcement.

Upcoming Market Events and Economic Data

Looking ahead, the week is packed with critical data and earnings. On the economic front, the ISM Manufacturing PMI for February is due later today, followed by the Fed’s Beige Book on Wednesday. The most anticipated release, however, is Friday’s February Jobs Report. Economists are forecasting a significant slowdown, with non-farm payrolls expected to add between 25,000 and 60,000 jobs, compared to 130,000 in January.

The earnings calendar also remains busy as the fourth-quarter season winds down. Target (TGT) is scheduled to report Tuesday morning, while tech bellwether Broadcom (AVGO) and retail giant Costco Wholesale (COST) will release results later in the week. Additionally, MongoDB (MDB) is set to report after today's closing bell, with analysts watching closely for signs of AI-driven growth in the database sector.
