NEW YORK, Jan 31 (Reuters) - U.S. stocks were little changed
on Thursday as investors were cautious after a mixed bag of
economic data, while stellar earnings from chipmaker Qualcomm
helped the Nasdaq index to edge higher.
The S&P 500 is on track to post its best month since October
2011 and its best January since 1997.
Investors expect a pullback in equities after the recent
gains, though they have bought on dips over the past four weeks.
The largest daily decline on the S&P 500 so far in 2013 was

derivatives for Charles Schwab in Austin, Texas.
"We could see an overly sensitive market to a bad number
tomorrow, given that we've been up without a major correction,
and that makes the market sensitive to the downside."
Data on Thursday showed a slight rise in weekly jobless
claims and incomes growing at the best pace since 2004,
underscoring how fragile the economic recovery still was.
Friday will also bring reports on consumer confidence, U.S.
manufacturing, construction spending and car sales.

Index was up 0.36 points, or 0.02 percent, at 1,502.32.
The Nasdaq Composite Index was up 6.99 points, or 0.22
percent, at 3,149.29.
The S&P 500 has advanced more than 5 percent in January
after legislators in Washington temporarily sidestepped a
"fiscal cliff" of automatic tax increases and spending cuts that
could have derailed the recovery. Better-than-expected corporate
earnings have added to the gains.
It would be the benchmark's largest monthly advance since a
more than 6 percent gain in October 2011 and the best January
advance since a 6.1 percent jump in 1997.
UPS shares lost 2.1 percent to $79.50 after

$32.72 after the U.S. Justice Department moved to stop

States if the transaction had been approved.

the 231 companies in the S&P 500 that have reported earnings
this season, 69.3 percent have exceeded expectations, a higher
proportion than over the past four quarters and above the
average since 1994.
Overall, S&P 500 fourth-quarter earnings are forecast to

the start of the earnings season but well below a 9.9 percent
profit growth forecast on Oct. 1, the data showed.
