NEW YORK (AP) -- U.S. stock futures are edging lower after a weak Chinese trade report outweighed optimism on corporate earnings.
Dow Jones Industrial futures are down 9 points at 15,213. The broader Standard & Poor's 500 futures are down 3 points at 1,643. Nasdaq futures are down 4 points at 2,971.
A decline Wednesday would break a four-day winning streak for the market.
Later Wednesday, investors will study the minutes from June's meeting of the Federal Reserve board of governors, along with a speech by Fed Chairman Ben Bernanke.
Encouraging U.S. economic news has sparked gains in some markets this week. But Wednesday's report that Chinese exports and imports each fell in June compared with last year raised questions about whether China's era of breakneck economic growth is over.
