Geopolitical tensions derail market rally. U.S. equities retreated sharply as Iran-related concerns overrode positive economic momentum. The broader market had built early strength on optimistic sentiment, but international developments shifted investor focus toward risk management. Major indices closed lower as traders reassessed exposure to geopolitical risk. This pattern reflects how quickly external political factors can override technical and fundamental market drivers. Energy markets showed particular volatility given regional tensions. Investors are now weighing whether this represents a temporary pullback or signals a broader shift in market dynamics as geopolitical risks remain elevated moving forward.
