NEW YORK, Jan 6 (Reuters) - U.S. stocks were little changed on Wednesday after data showed the U.S. services sector grew in December, but at a marginal pace.
The Institute for Supply Management said its services index rose to 50.1 from 48.7 in November. The reading was below economists' forecast of 50.5, according to a Reuters survey. A reading above 50 indicates expansion. For details, see [ID:nN06314739]
"The overall number was pretty good, but it wasn't especially positive. There's still a lot to be desired. I think this will be overlooked in trading though, since there wasn't a huge shock in the headline number," said Dan Cook, senior market analyst at IG Markets in Chicago.
The Dow Jones industrial average .DJI was up 2.04 points, or 0.02 percent, at 10,574.06. The Standard & Poor's 500 Index .SPX was down 0.99 points, or 0.09 percent, at 1,135.53. The Nasdaq Composite Index .IXIC was down 1.95 points, or 0.08 percent, at 2,306.76.
In corporate news, Family Dollar Stores Inc FDO.N gained 11.7 percent to $30.67 after the retailer reported first-quarter earnings that beat expectations. And 99 Cents Only Stores NDN.N gained 7 percent to $14.27. [ID:nN06135812]
Walgreen Co WAG.N fell nearly 1 percent to $36.68 after the company said sales at its drugstores open for at least a year fell in December instead of rising as Wall Street had expected.
Dow Chemical Co (DOW.N) jumped nearly 3 percent to $31.35 after Barclays Capital upgraded the stock to "overweight" from "equal-weight."
U.S. Senate Banking Committee Chairman Christopher Dodd was to announce he will not seek re-election, sources said. The Connecticut Democrat has been dogged by questions over his financial industry connections and faces a tough re-election bid. The S&P Financial Index .GSPF was down 0.1 percent.
In other economic data, the ADP Employer Services report showed a smaller-than-expected slowdown in job losses in December. ADP is a precursor to the closely watched government non-farm payrolls report due Friday. Economists look for a loss of 8,000 non-farm jobs after a surprisingly small total of 11,000 job losses in November. [ID:nN06314739][ID:nN04238910]
