Lockheed Martin lost as much as four percent of its total value in the moments after US president-elect Donald Trump tweeted that the cost of the military jet maker’s project to build advanced F-35 Lightning II fighters was “out of control.”

Panicked investors dumping stock initially shaved off around $3.5 billion (£2.75 billion) from the company’s value, though the share price had recovered somewhat by the close of trading on Monday, leaving it nearly 2.5 percent down on the previous day, or a dip of around $2 billion (£1.57 billion).
