Lockheed Martin shares drop as Trump says F-35 costs are “out of control”

Shares of Lockheed Martin fell Monday, wiping out nearly $4 billion of the company's market value, as President-elect Donald Trump tweeted that making F-35 fighter planes is too costly and that he will cut "billions" in costs for military purchases. In a statement Monday, Lockheed said that it has worked to lower the price of the F-35 by more than 60 percent and said it expects the aircraft to cost $85 million in 2019 and 2020.
