The three major U.S. stock indexes, however, closed little changed for the day, following a set of mixed economic data.
The Dow Jones industrial average fell 25.56 points or 0.15 percent, to end unofficially at 16,826.28. The S&P 500 dipped 0.74 of a point, or 0.04 percent, to finish unofficially at 1,960.22. But the Nasdaq Composite added 10.25 points or 0.23 percent, to close unofficially at 4,408.18. (Reporting by Angela Moon; Editing by Jan Paschal)
