The U.S. stock market experienced a volatile start to the week on Monday, March 2, 2026, as investors grappled with escalating geopolitical tensions in the Middle East. Following a weekend of significant military activity involving U.S. and Israeli strikes on Iranian targets, markets opened with sharp losses before finding a degree of stability in afternoon trading. The conflict has sent shockwaves through the commodities market, particularly oil and gold, while triggering a notable rotation within equity sectors.
Major Market Indexes and Afternoon Performance
As of the afternoon session, the major market indexes are showing a mixed but resilient performance compared to their early morning lows. The S&P 500 (SPX) is currently trading near 6,828, down approximately 0.3% after paring an initial drop of 1.2%. The Dow Jones Industrial Average (DJI) remains under pressure, down about 75 points or 0.2% to hover around 48,540. In contrast, the tech-heavy Nasdaq Composite (IXIC) has managed to edge into positive territory, rising 0.3% to 22,505, buoyed by a recovery in select semiconductor and defense-related technology firms.
Market breadth remains skewed to the downside, with nearly 400 constituents of the S&P 500 trading in the red. However, the equal-weighted S&P 500 index continues to outperform the cap-weighted version on a year-to-date basis, reflecting a broader market rotation away from the "Magnificent Seven" and toward cyclical and value-oriented stocks.
Sector Spotlight: Energy and Defense Lead the Way
The Energy sector is the standout performer this afternoon, jumping over 1.4% as global oil prices surged. Brent Crude rose 8% to $78.70, while West Texas Intermediate (WTI) climbed 6.7% to $71.55 following concerns over potential disruptions in the Strait of Hormuz. Major oil producers like Exxon Mobil (XOM) and Occidental Petroleum (OXY) both saw gains of over 2% in mid-afternoon trade.
Defense contractors are also seeing significant inflows. Lockheed Martin (LMT) climbed 3.5%, and RTX (RTX) rallied 4.6% as the conflict raised expectations for increased defense spending. Conversely, travel-related stocks are the day's biggest laggards, with airline and cruise line operators facing selling pressure due to rising fuel costs. MGM Resorts (MGM) fell 5.1%, while Dollar Tree (DLTR) lost 2.9% as investors weighed the impact of higher energy prices on consumer discretionary spending.
Major Stock News and Corporate Developments
Nvidia (NVDA) remains a focal point for investors after reporting record fiscal fourth-quarter revenues of $68.1 billion, a 73% increase year-over-year. The stock rose 3% in afternoon trading, acting as a primary support for the Nasdaq. Meanwhile, Palantir Technologies (PLTR) jumped 6.3%, the largest gain in the S&P 500 today, as its defense-oriented software solutions gain renewed attention amid the Middle East crisis.
In the broader Big Tech space, the picture is more nuanced. While Apple (AAPL) is trading at a premium relative to its long-term model value, it has faced headwinds alongside Microsoft (MSFT), which is down roughly 17% year-to-date in 2026. Tesla (TSLA) and Alphabet (GOOGL) are also seeing muted performance as investors demand greater profit visibility from AI investments.
Upcoming Market Events and Economic Data
Investors are bracing for a heavy week of economic data, colloquially known as "Jobs Week." Key releases include the ADP Employment Report on Wednesday and the highly anticipated February Non-Farm Payrolls on Friday. Analysts expect a slowing of job growth to approximately 60,000, with the unemployment rate holding steady at 4.3%.
Earlier today, the ISM Manufacturing PMI for February was released, coming in at 52.0, indicating continued expansion in the manufacturing sector. However, the "Prices Paid" component jumped sharply to 70.5, raising fresh concerns about sticky inflation. This data, combined with rising oil prices, may complicate the Federal Reserve's path toward interest rate cuts later this year. On the earnings front, markets are looking ahead to reports from Broadcom (AVGO), Costco (COST), and Target (TGT) later this week.
