NEW YORK -- The steep losses finally stopped Wednesday as the stock market turned calm, a day after one of its biggest sell-offs of the year. Major indexes wavered between minor gains and losses in midday trading.
Boeing, one of the 30 large companies in the Dow Jones industrial average, said it expects to deliver more airplanes and raised its estimates for profits this year. Boeing's quarterly earnings also beat analysts' estimates. Its stock rose $1, or 1.4 percent, to $73.82.

The Dow climbed 9 points to 13,111 shortly after noon. The Standard & Poor's 500 index slipped less than one point to 1,412 while the Nasdaq composite index sank seven points to 2,983.
"Today we're assessing the damage," said Mark Luschini, chief investment strategist at Janney Montgomery Scott. "Everybody just got clobbered yesterday."
Lower corporate revenue and expectations for the rest of the year drove the Dow down 243 points Tuesday, its third-biggest drop this year. DuPont, 3M, UPS and Xerox all reported lower sales than a year ago.
"It seemed out of the blue, but what we were seeing was stock prices adjusting to corporate profitability," Luschini said.
Facebook was poised for its best day since its stock market debut in May. The company said late Tuesday that 14 percent of its advertising revenue came from mobile devices, allaying some investor concerns.

Another Dow stock, AT&T, said it added the fewest wireless customers since 2003, far behind Verizon Wireless. AT&T's results still managed to beat the estimates of financial analysts. AT&T fell 25 cents to $34.75.
A measure of manufacturing in China, the world's second-largest economy after the United States, improved this month to a three-month high. China's white-hot economic growth has been slowing.
