The Dow Jones Industrial Average topped the 14,000 barrier momentarily Friday for the first time since October 2007, helped by some encouraging jobs data and solid earnings reports.
The Dow was just above the benchmark at 12:00 pm (1700 GMT), trading up 1.0 percent from Thursday at 14,001, having earlier pushed just over 14,004.
The last time the Dow was at that level was October 17, 2007, weeks before the markets began to plummet as the country plunged into recession.
The broad-based S&P 500 added 14.81 points (0.99 percent) at 1,512.92, while the tech-heavy Nasdaq Composite gained 34.55 (1.10 percent) at 3,176.68.
The markets took in stride the January jobs numbers: unemployment ticked up a notch to 7.9 percent and only 157,000 jobs were generated, fewer than expected.
But revised data for all of 2012 gave a much better picture, with monthly net job generation at 181,000 instead of the earlier figure of only 153,000.
