Here are the five worst Dow Jones industrial average performers as trade dispute escalates

The stock market has endured a bumpy two weeks since President Donald Trump said he would raise tariffs on $200 billion in Chinese imports from 10% to 25%, producing some winners and losers.

The damage spread last week after China said it would hike retaliatory tariffs on U.S. exports to that country to as much as 25%.

While the Dow Jones industrial average has pared severe losses several times over the period as hopes for a settlement wax and wane with each Trump tweet or White House update, the Dow was down 178 points, or 0.7%,last week after recovering much of the losses suffered Monday and Tuesday. It has also fallen 741 points, or 2.8%, during the past two weeks.

The Dow closed down 99 points to 25,764 on Friday, though investors remain encouraged by signals that Washington and Beijing still plan to continue negotiations.

Here are the companies with the steepest percentage declines:

Intel is the biggest Dow loser, dropping 10.71% since the president first tweeted about the higher tariffs May 5. Nearly 27% of its revenue came from China in 2018, according to Statista.

Another poor performer is Apple, which has fallen 9.46%. The company both assembles and sells products in China, making it sensitive to price increases that dampen Chinese consumers’ confidence.

Although the tariffs haven't yet affected Apple’s products, the company would be hammered if the trade war escalates further to include all Chinese imports to the U.S. The technology company has more Chinese suppliers than ever, according to its supplier list. China, including Hong Kong and Taiwan, represented 19.2% of Apple revenue in 2018.

Caterpillar, Boeing and 3M have been slammed on trade war fears, as well.

Caterpillar shares have tumbled about 9%. China sales make up 5% to 10% of Caterpillar’s total revenue, the company says. The construction and mining equipment giant’s sales in the Asia-Pacific region climbed in 2018 because of the rising demand in China.

3M stock slid 8.5% as the conglomerate cut its 2019 profit outlook because of weak demand in China earlier this year, and it said it would lay off 2,000 workers. Asia-Pacific is 3M’s biggest market outside the U.S.

Boeing is down more than 5%.. More than half of all commercial jetliners flying in China are made by Boeing. Boeing generates more than $1 billion in economic activity in the country, according to the company.
