(AP) — The latest on developments in financial markets (all times local):

4 p.m.
Another flare-up in trade tensions between the U.S. and China sent the stock market sharply lower for the second time this week.

The Dow Jones industrial average lost 572 points Friday, having traded down as much as 767. It fell modestly for the week.

Caterpillar dropped 3.5 percent, the most in the Dow.

Caterpillar and other industrial companies rely heavily on overseas sales and could suffer if commerce is curtailed by rising trade barriers.

The latest market swing came after President Donald Trump proposed tariffs on an additional $100 billion in Chinese goods.

The Dow recovered some of its worse losses to end down 2.3 percent at 23,932.

The S&P 500 fell 58 points, or 2.2 percent, to 2,604.

The Nasdaq composite dropped 161 points, or 2.3 percent, to 6,915.

The Dow Jones industrial average fell as much as 620 points in afternoon trading Friday, its latest big swing this week.

Aerospace giant Boeing fell the most in the Dow, dropping 3.4 percent. Boeing and other industrial companies rely heavily on overseas sales and could suffer greatly if global commerce is curtailed by rising trade barriers.

Technology companies and banks also fell. Apple lost 2 percent and JPMorgan Chase gave up 2.9 percent.

The Dow fell 588 points, or 2.4 percent, at 23,909.

The S&P 500 fell 56 points, or 2.1 percent, to 2,607.

The market has been on a bumpy ride this week as traders try to get a sense of whether a trade dispute between the two nations will escalate. President Donald Trump has proposed more tariffs on Chinese goods.
