NEW YORK, Aug 9 (Reuters) - U.S. stocks fell on Friday
following renewed jitters over the U.S.-China trade war, capping
a week of trading that saw big swings and high volume.
President Donald Trump said the United States and China were
pursuing trade talks but he was not ready to make a deal,
fanning fears over the impact of the trade war on the global
economy.
Trump also said the United States would continue to refrain
from doing business with Chinese telecoms equipment giant Huawei
Technologies HWT.UL . The week was marked by wild swings, but indexes finished
nearly flat on the week. This week's volume on U.S. exchanges
was also the biggest weekly total of the year, exceeding 41
billion shares.
On Friday, all three indexes were down more than 1% in early
trading and rebounded later in the session, with the Dow briefly
turning positive at one point. This left a 315-point swing
between the blue-chip index's high and low of the day.
The frequent comments on trade are "leaving investors
whipsawed," said Rick Meckler, partner, Cherry Lane Investments,
a family investment office in New Vernon, New Jersey.
"As volatility has picked up, you've gotten more interest on
the part of traders, and that in turn has led to even higher
volume," he said. "When you get moves like this and reversals,
it brings a lot of high-frequency traders in and short-term
traders."
Shares of chipmakers and other tariff-sensitive technology
companies .SPLRCT fell, with the Philadelphia SE Semiconductor
index .SOX down 1.8%.
The Dow Jones Industrial Average .DJI fell 90.75 points,
or 0.34%, to 26,287.44, the S&P 500 .SPX lost 19.44 points, or
0.66%, to 2,918.65 and the Nasdaq Composite .IXIC dropped
80.02 points, or 1%, to 7,959.14.
Shares of Amgen AMGN.O jumped 5.9% after news that a U.S.
judge said patents relating to the Amgen's blockbuster
rheumatoid arthritis drug Enbrel were valid, denying a challenge
by Novartis AG NOVN.S . Uber Technologies Inc UBER.N shed 6.8% after the
ride-hailing company reported a record $5.2 billion quarterly
loss and revenue that fell short of Wall Street targets.
Nektar Therapeutics NKTR.O shares also plunged, a day
after the drug developer flagged manufacturing issues with its
experimental cancer drug bempeg.
Declining issues outnumbered advancing ones on the NYSE by a
1.99-to-1 ratio; on Nasdaq, a 2.07-to-1 ratio favored decliners.
The S&P 500 posted 46 new 52-week highs and nine new lows;
the Nasdaq Composite recorded 56 new highs and 129 new lows.
