U.S. stocks closed in negative territory following seesaw trading Wednesday, as investors weighed a disappointing private-sector jobs report against slightly better- than-expected non-manufacturing index.

The U.S. private sector added 175,000 jobs in January, the lowest level since August, partly affected by the cold weather, private payroll processor ADP said in a report on Wednesday.

The private gauge of labor market pointed to a weak non-farm payroll report slated to be released Friday by the Labor Department, putting a damper on the market. However, Wall Street recouped part of earlier losses after data showed that economic activity in the U.S. non-manufacturing sector grew in January. The reading registered 54, slightly higher than the seasonally adjusted reading of 53 in December, the Institute for Supply Management said Wednesday.
