Jan 11 (Reuters) - Wall Street's main indexes slipped from
record levels on Monday as investors locked in gains after a
stellar vaccine and stimulus-fueled rally, while Twitter shares
slumped following the permanent suspension of President Donald
Trump's account.
Shares of the micro-blogging site TWTR.N slumped about 9%,
knocking off more than $2.5 billion from the company's market
value. Bets on a rebound in business activity in 2021 fueled by
COVID-19 vaccine rollouts, larger checks and infrastructure
spending under President-elect Joe Biden have underpinned Wall
Street's rise to recent peaks, with focus shifting to
economy-linked stocks from the tech-heavy growth names.
"After a very quick run, people start to get a little bit
nervous and take money off the table," said Robert Pavlik,
senior portfolio manager at Dakota Wealth in Fairfield,
Connecticut.
Nine of the 11 major S&P sectors were down in early trading
with consumer discretionary .SPLRCD being the biggest loser,
weighed down by a 6% drop in Tesla Inc TSLA.O after a 11-day
winning streak.
Healthcare stocks .SPXHC hit a record high for the fifth
straight session, while rate-sensitive financials .SPSY
gained, tracking higher U.S. Treasury yields. US/
After official data pointed to a significant slowdown in
labor market recovery on Friday, investors will focus on
inflation, retail sales and consumer sentiment indicators this
week to gauge the extent of economic damage.
Fourth-quarter results from JP Morgan JPM.N , Citi C.N
and Wells Fargo WFC.N on Friday will kick-off the earnings
season, which could offer more clues on if company executives
reflect the enthusiasm of a rebound in 2021 earnings and the
economy. "People are taking profits ahead of the earnings season, and
investors are beginning to reflect on the market's heights,"
Peter Cardillo, chief market economist at Spartan Capital
Securities in New York.
"This Friday, the earnings season begins, and with the
market at high levels, the question is will this justify the
current price-earnings structure."
At 09:54 a.m. ET, the Dow Jones Industrial Average .DJI
fell 167.89 points, or 0.54%, to 30,930.08, the S&P 500 .SPX
lost 28.84 points, or 0.75%, to 3,796.14 and the Nasdaq
Composite .IXIC lost 161.41 points, or 1.22%, to 13,042.36.
Later in the day, U.S. House of Representatives Democrats
plan a vote to urge Vice President Mike Pence to take steps to
remove Trump from office after his supporters' deadly storming
of the Capitol, before attempting to impeach him again.
Boeing Co BA.N fell 3% after a 737-500 jet operated by
Indonesian Sriwijaya Air crashed on Saturday, with 62 people on
board. Declining issues outnumbered advancers by a 2.8-to-1 ratio
on the NYSE and by a 1.9-to-1 ratio on the Nasdaq.
The S&P 500 posted 14 new 52-week highs and no new low,
while the Nasdaq recorded 78 new highs and two new lows.
