UPDATE 5:00 p.m. EST
Shares of Boeing reversed course, ending the day slightly higher following a somewhat turbulent day of trade for the company.
Tuesday morning, President-elect Donald Trump sent a tweet about the company that sent the plane maker's stock on a downward spiral.
The tweet also prompted the Air Force to release a statement on Air Force One, saying, "We have budgeted $2.7 billion ... but expect this number to change."
Here's the moment in the day when Boeing shares turned positive after Trump's tweet.
People on Twitter tried to figure out what prompted Trump's original tweet Tuesday morning.
UPDATE 12:10 p.m. EST
Boeing released a statement on Trump's comments, saying it was only under contract for $170 million to "help determine the capabilities of these complex military aircraft."
It's not clear where Trump got the $4 billion number.
In a Tuesday morning tweet, President-elect Donald Trump criticized the cost of the still-being-built new model of Air Force One, the signature plane of the White House that doubles as a mobile Oval Office.
He said Boeing, the nation's leading aircraft manufacturer, was building a "brand new" version of the plane that will cost more than $4 billion.
The stock market noticed, and Boeing's stock slipped 1 percent within minutes, CNBC reports.
Boeing is building a brand new 747 Air Force One for future presidents, but costs are out of control, more than $4 billion. Cancel order!— Donald J. Trump (@realDonaldTrump) December 6, 2016
Here's the original tweet.

"I think Boeing is doing a little bit of a number," he said. Reuters reported that the Air Force previously said it planned $1.65 billion for two replacement presidential jets.
Trump supporters took this as a sign that he would not blindly accept pricey deals.
