NEW YORK (AP) — U.S. stocks are opening lower as energy companies fall with oil prices and industrial companies slip as investors focus on the U.S.-China trade dispute.

Boeing and Caterpillar both fell 1.3 percent Thursday after China criticized the Trump administration's threat to place taxes on hundreds of billions of dollars in imports.

Intel lost 1 percent after the company said its CEO resigned after it learned he had a relationship with an employee. It described the relationship as consensual.

The Dow Jones industrials fell 81 points, or 0.3 percent, to 24,577. The Dow has dropped for seven straight days.

The S&P 500 index lost 3 points, or 0.1 percent, at 2,763 and the Nasdaq composite added 5 points to 7,785.
