NEW YORK — U.S. stocks closed mostly lower after signs emerged that Americans are spending at a slower pace.

The Dow Jones industrial average fell 47.15 to 12,896.67. The S&P 500 fell 6.44 to 1,367.58. The Nasdaq index rose 0.04 point to 2,976.12.

CHICAGO — Boeing Co. said Thursday that it has delivered 287 commercial airplanes so far this year, including 11 of its new 787s.

The 787 deliveries are being closely watched because Boeing is ramping up production of that plane at its Everett, Wash., factory and its new line in North Charleston. Boeing delivered six of those planes in the second quarter, all from Washington.

Boeing said it delivered 150 commercial planes in the second quarter. Besides the 787s, there were 109 737s, seven superjumbo 747s, six long-haul 767s and 22 777s.

Financial markets were underwhelmed, and even ECB President Mario Draghi conceded that the impact of the rate cut could be “muted,” given the low demand for credit in the slow economy.
