It took the whole day, but stocks came all the way back. Bruised once again by uncertainty about European debt, the U.S. stock market fell sharply Thursday at the open, then steadily gained ground for six hours. By the close, the Dow Jones industrial average had shaved its loss to less than three points.

It was the first decline of the year for the Dow. The Standard & Poor’s 500 index gained just under four points and managed to extend its January winning streak to three days.
