News Summary: Boeing leads stock market lower

The Associated Press

BAD DREAMLINER: More problems for Boeing's 787 Dreamliner sent the aircraft maker's stock down sharply Wednesday, dragging the Dow Jones industrial average lower. Japan's two biggest airlines grounded all their Boeing 787s for safety checks after one was forced to make an emergency landing.

SIZE MATTERS: JPMorgan Chase, the country's largest bank, and Goldman Sachs reported quarterly results that trounced analysts' estimates and their stocks rose. Smaller financial firms reported weaker earnings and their stocks sank.

FINAL SCORE: The Dow lost 24 points to close at 13,511. The S&P 500 index inched up less than one point to 1,472.
