Why Stocks Dropped Today | February 28, 2026

What Happened Today

On February 28, 2026, the stock market experienced a downturn, with the S&P 500 dropping 0.5%, NASDAQ down 0.3%, and the Dow falling 1.1%. The declines were largely driven by escalating tensions in the Middle East, particularly after Iran threatened retaliation against the U.S. for a recent attack on Kharg Island.

The situation intensified further with reports of civilian casualties from a strike in Iran, causing investors to worry about the potential for broader conflict and its impact on global markets. These fears contributed to the S&P 500 experiencing its first three-week losing streak in almost a year, as many investors chose to sell off stocks in a cautious response to the geopolitical turmoil.

Sector Breakdown

• Energy: Crude oil prices surged due to fears of escalating conflict, affecting energy stocks positively.
• Consumer Discretionary: Retail stocks suffered as consumer confidence wavered amid geopolitical uncertainty.
• Industrials: Companies tied to defense and security saw mixed results as markets reacted to the news.
• Technology: Tech stocks were pressured as investors shifted away from growth-oriented sectors in favor of safer assets.

What This Means for Your Portfolio

For most retail investors, this means it's a good time to review your portfolio. With stocks declining, it may be wise to consider if you are overexposed to sectors that could be affected by global tensions, while also looking for potential buying opportunities in more stable sectors.
