June 10 (Reuters) - Wall Street's main indexes climbed on
Monday, as investors were relieved after the United States
abandoned its plans to impose tariffs on Mexican goods.
Mexico on Friday agreed to step up efforts to stem the flow
of illegal Central American migrants, following threats from
U.S. President Donald Trump to impose a 5% import tariffs on all
Mexican goods starting Monday. "Both the U.S. economy and the Mexican economy would have
been worse off had the tariffs been imposed," said David Kass,
professor of finance at the University of Maryland.
"Investors are also optimistic today in the hope that the
trade war with China will also be resolved in the near future,"
Kass said.
U.S. automakers, which have long built vehicles in Mexico,
traded higher, with General Motors Co GM.N gaining 2.4% and
Ford Motor Co F.N 1.1%. Corona beer maker Constellation Brands
STZ.N , which has significant Mexico exposure, was up 2.4%.
Technology stocks .SPLRCT rose 1.5% and provided the
biggest boost among the nine major S&P sectors trading higher.
Large-cap companies, including Apple Inc AAPL.O , Microsoft
Corp MSFT.O , Amazon.com AMZN.O and JPMorgan Chase JPM.N ,
rose between 2% and 3.5% and bolstered the markets.
However, shares of United Technologies Corp UTX.N and
Raytheon Co RTN.N came under pressure after Trump said he was
a "little concerned" about their merger as it could take away
competition in the sector.
The two companies on Sunday agreed to merge to create a new
firm worth about $121 billion. United Technologies Corp UTX.N
was down 2.3%, while Raytheon Co RTN.N was up 2.1%.
At 10:24 a.m. ET, the Dow Jones Industrial Average .DJI
was up 165.45 points, or 0.64%, at 26,149.39. The S&P 500 .SPX
was up 21.58 points, or 0.75%, at 2,894.92 and the Nasdaq
Composite .IXIC was up 112.88 points, or 1.46%, at 7,854.98.
Only the defensive utilities .SPLRCU and real estate
sectors .SPLRCR were trading lower.
Other gainers included chemical marker LyondellBasell
Industries LYB.N , which rose 5.9% following a 37 million share
buyback program on Monday. Kraft Heinz Co KHC.O gained 5.3% after the packaged food
company said the numbers it restated last month were accurate
following completion of an internal investigation. Salesforce.com Inc CRM.N slid 4.5%, the most among S&P
companies, after the cloud-based services provider said it would
buy big data firm Tableau Software DATA.N for $15.3 billion.
Tableau jumped 34.7%. Advancing issues outnumbered decliners by a 2.28-to-1 ratio
on the NYSE and by a 2.74-to-1 ratio on the Nasdaq.
The S&P index recorded 51 new 52-week highs and no new low,
while the Nasdaq recorded 74 new highs and 21 new lows.
