NEW YORK, Feb 8 (Reuters) - The Nasdaq composite stock index
closed at a 12-year high and the S&P 500 index at a five-year
high after stronger U.S. and international trade data improved
the outlook for economic growth.
The S&P 500 also posted a sixth straight week of gains for
the first time since August.
Data showed Chinese exports grew more than expected, while
another report showed the U.S. trade deficit had narrowed in
December, indicating the U.S. economy strengthened in the fourth
"That may have sent a ray of optimism," said Fred Dickson,
chief market strategist at D.A. Davidson & Co in Lake Oswego,
Trading volume on Friday was below average for the week as a
blizzard swept into the northeastern United States.
The technology sector led the day's gains, with the S&P 500
technology index up 1.0 percent. Gains in professional
network platform LinkedIn Corp and AOL Inc
after they reported quarterly results helped the sector.
The U.S. stock market has posted strong gains since the
start of the year, with the S&P 500 up 6.4 percent since Dec.
31. But the advance has slowed in recent days, with
fourth-quarter earnings winding down and few incentives to
continue the rally on the horizon.
"I think we're in the middle of a trading range and I'd put
plus or minus 5.0 percent around it. Fundamental factors are
best described as neutral," Dickson said.
The Dow Jones industrial average ended up 48.92
points, or 0.35 percent, at 13,992.97. The Standard & Poor's 500
Index was up 8.54 points, or 0.57 percent, at 1,517.93.
The Nasdaq Composite Index was up 28.74 points, or 0.91
percent, at 3,193.87, its highest closing level since November
For the week, the Dow was down 0.1 percent, the S&P 500 was
up 0.3 percent and the Nasdaq up 0.5 percent.
Shares of LinkedIn jumped 21.3 percent to $150.48 after it
announced quarterly profits and gave a bullish forecast for the
AOL Inc shares rose 7.4 percent to $33.72 after the
online company reported higher quarterly profit, boosted by a 13
percent rise in advertising sales.
Shares of Dell closed at $13.63, up 0.7 percent,
after briefly trading above a buyout offering price of $13.65
during the session.
Dell's largest independent shareholder, Southeastern Asset
Management, said it plans to oppose the buyout of the personal
computer maker, setting up a battle for founder Michael Dell.
Signs of economic strength overseas buoyed sentiment on Wall
Street. Chinese exports grew more than expected in January,
while imports climbed 28.8 percent, highlighting robust domestic
demand. German data showed a 2012 surplus that was the nation's
second highest in more than 60 years, an indication of the
underlying strength of Europe's biggest economy.
Separately, U.S. economic data showed the trade deficit
shrank in December to $38.5 billion, its narrowest in nearly
three years, indicating the economy did much better in the
fourth quarter than initially estimated.
Earnings have mostly come in stronger than expected since
the start of the reporting period. Fourth-quarter earnings for
S&P 500 companies now are estimated up 5.2 percent versus a year
ago, according to Thomson Reuters data. That contrasts with a
1.9 percent growth forecast at the start of the earnings season.
Molina Healthcare Inc surged 10.4 percent to $31.88
as the biggest boost to the index after posting fourth-quarter
The CBOE Volatility index, Wall Street's so-called
fear gauge, was down 3.6 percent at 13.02. The gauge, a key
measure of market expectations of short-term volatility,
generally moves inversely to the S&P 500.
"I'm watching the 14 level closely" on the CBOE Volatility
index, said Bryan Sapp, senior trading analyst at Schaeffer's
Investment Research. "The break below it at the beginning of the
year signaled the sharp rally in January, and a rally back above
it could be a sign to exercise some caution."
Volume was roughly 5.6 billion shares traded on the New York
Stock Exchange, the Nasdaq and the NYSE MKT, compared with the
2012 average daily closing volume of about 6.45 billion.
Advancers outpaced decliners on the NYSE by nearly 2 to 1
and on the Nasdaq by almost 5 to 3.
