Why Did Lockheed Martin Stock Drop Today?
Lockheed Martin (LMT) stock fell 2.7% despite a positive announcement. The company demonstrated a partnership with Saildrone, using a Saildrone Surveyor to fire Lockheed-built missiles. The test also showcased threat-identification and electronic warfare systems. Lockheed aims to expand this collaboration, potentially increasing its market for weapons systems. The stock's decline contradicts the positive news.
