NEW YORK, July 24 (Reuters) - U.S. stocks slid on Thursday as major earnings disappointed, oil prices halted their decline and data showing weakness in the economy added to concerns about the profit outlook.
A wider-than-expected quarterly loss at Ford Motor Co <F.N> and a profit miss at Dow Chemical <DOW.N>, the largest U.S. chemical maker, helped to halt stocks' two-day bounce.
Brokerage downgrades of bellwethers Boeing Co <BA.N>, down more than 5 percent, McDonald's Corp <MCD.N>, off more than 2 percent and AT&T <T.N>, off nearly 3 percent, generated more headwinds.
U.S. crude futures, which had sunk to a seven-week low, were seesawing between negative and positive territory, trading at about $125 a barrel.
The halt in oil's decline seemed to be weighing on the market, said Richard Sparks, senior equities analyst at Schaeffer's Investment Research in Cincinnati, Ohio. "I think maybe the expectations for a continued fall aren't being met today, and that's putting some pressure on stocks today."
