Defense Sector Catalysts Ignite Rocket Lab’s Rebound
Rocket Lab’s 6.4% surge follows a $9.8 billion missile contract awarded to Lockheed Martin and accelerated F-35 program adjustments. The stock’s rebound from a 7% weekly low aligns with heightened defense spending signals, including the E-4C 'doomsday plane' flight tests and U.S. troop expansion in Poland. Options data reveals aggressive call buying at 46.5–47.5 strike prices, suggesting positioning for a continuation of the sector-driven rally.

Aerospace & Defense Sector Rally Amplifies Rocket Lab’s Momentum
The Aerospace & Defense sector surged on multiple large contracts, including Lockheed Martin’s record $9.8B deal and F-35 program updates. Rocket Lab’s 6.4% gain outperformed sector leader Lockheed Martin’s 1.14% rise, reflecting speculative positioning in smaller defense innovators. The sector’s 1.13% average intraday gain underscores broad-based optimism about military modernization budgets.
