Stock Market Updates for March 3, 2026

Wall Street Wraps Up Mixed as Tech, Defense, and Energy Lead Gains

On Monday, U.S. stock markets ended with a split performance, as technology, defense, and energy shares provided support amid a generally cautious trading environment. Investors remained wary due to increased geopolitical risks and ongoing market fluctuations, but select sectors managed to show resilience. Out of the three major indexes, two closed higher while one finished lower.

Index Performance Overview

• Dow Jones Industrial Average: Fell by 0.2% (down 73.14 points), closing at 48,904.78. Of the 30 stocks in the index, 18 declined and 12 advanced.
• Nasdaq Composite: Rose by 80.65 points, or 0.4%, ending the day at 22,748.86.
• S&P 500: Added 2.74 points to finish at 6,881.62, nearly unchanged. Seven out of eleven sectors in the index posted losses. Notably, the Energy Select Sector SPDR (XLE) gained 2%, Industrials Select Sector SPDR (XLI) rose 1%, and Technology Select Sector SPDR (XLK) increased by 0.9%. In contrast, Consumer Staples Select Sector SPDR (XLP) dropped 1.4%. The CBOE Volatility Index (VIX), a measure of market fear, climbed 8% to 21.44.

Tech and Defense Stocks Offset Broader Weakness

Gains in technology and defense companies helped counteract declines in other areas of the market. Early trading was unsettled by developments in Iran and concerns about potential disruptions to energy supplies, which contributed to increased volatility and a defensive approach among investors. The overall market softness reflected ongoing worries about global stability and its potential impact on the economy.

Despite these headwinds, technology shares—especially those linked to artificial intelligence and innovation—attracted buyers. Defense and aerospace companies also advanced, as rising geopolitical tensions fueled expectations for continued or increased military spending. These sector-specific strengths helped limit losses for the major indexes and brought some stability by the close, even as uncertainty persisted.

Among notable movers, NVIDIA Corporation (NVDA) gained 3%, while Northrop Grumman Corporation (NOC) advanced 6%. NVDA currently holds a Zacks Rank #2 (Buy), and NOC is rated #3 (Hold).

Energy Sector Surges Amid Middle East Tensions

Energy stocks outperformed on March 2, 2026, as escalating conflict in the Middle East—marked by renewed military action in Iran—sparked concerns over global oil supply. The possibility of disruptions at the Strait of Hormuz, a vital passage for about 20% of the world’s oil, drove oil prices sharply higher and boosted shares of energy producers and major oil companies.

Both Brent and WTI crude prices soared, fueling optimism in the energy sector while prompting investors to move away from more interest-rate-sensitive and riskier segments. WTI crude settled up 6.28% (an increase of $4.21) at $71.23 per barrel, while Brent crude climbed 6.68% (up $4.87) to $77.74 per barrel. The rally in oil prices raised expectations for improved earnings among producers and exploration firms, making energy stocks a relative safe haven during a period of broader market caution. This strength in energy helped soften the impact of declines elsewhere.

Key Economic Data

The Institute for Supply Management reported that the Manufacturing PMI for February stood at 52.4, while January’s figure was unchanged at 52.6.
