The Institute for Supply Management's manufacturing index rose to 54.2, a surprise improvement from January's 53.1 and the best reading since June 2011.
The Dow Jones industrial average and Nasdaq rose 0.3%, while the S&P 500 edged up 0.2%, recovering from nearly 1% declines earlier in the day. The Dow is now less than 1% away from its all-time high reached in 2007, and the S&P is off less than 4%.

The strong manufacturing report "takes a little bit of the sting away from the sharp decline in personal income in January," said Jim Baird, chief investment strategist for Plante Moran Financial Advisors.
The Commerce Department reported that personal income fell 3.6% in January, which was the steepest month-to-month drop in 20 years and much worse than economists were expecting. Personal spending notched up 0.2%, as expected.
While manufacturing activity continues to pick up, the near-term outlook for the economy remains murky, said Baird, noting that the consumer sector is particularly vulnerable.
"Confidence has been improving, but the looming cuts in federal spending could throw some cold water on that emerging optimism," he said.
Assuming that no last-minute deal is reached, $85 billion in automatic spending cuts will go into effect Friday, although it may be weeks or months before that pain is felt.
