Amentum is trading 4.1% up at $23.11 as defense stocks rally on a major missile interceptor production deal involving Northrop Grumman and Lockheed Martin.
- The sector-wide surge follows news of a significant contract with the U.S. Department of War, boosting sentiment across defense-related equities.
- Broader market conditions are providing additional tailwinds, with the S&P 500 and Nasdaq both gaining more than 1%.
- The move appears to be driven by sector momentum and risk-on sentiment rather than any new company-specific news or earnings catalysts.
