May 5 (Reuters) - Wall Street's main indexes jumped on
Tuesday as a recovery in oil prices lifted battered energy
stocks and a slew of countries eased coronavirus-induced
restrictions in an attempt to revive their economies.
Some hard-hit countries, including Italy, as well as a
handful of U.S. states are tentatively easing stay-at-home
orders this week, raising hopes for a recovery in oil demand.
All the major S&P 500 sub-indexes were trading higher, with
the energy sector .SPNY rising 2.4%, but the index is a big
laggard across sectors with a 36.6% decline this year.
Healthcare stocks .SPXHC were also in the spotlight with
Pfizer Inc PFE.N up 2.8% after it announced a venture with its
German partner had started delivering doses of its experimental
coronavirus vaccines for human testing in the United States.
Regeneron Pharmaceuticals Inc REGN.O jumped 5.6% as it
said its experimental antibody cocktail for COVID-19 may be
available for use by the end of summer or fall, as it ramps up
efforts to start human trials in June. Market-leading growth stocks such as Microsoft Corp
MSFT.O , Amazon.com Inc AMZN.O and Apple Inc AAPL.O
provided the biggest boost for a second day.
The S&P 500 .SPX has climbed about 30% from its March lows
on the back of unprecedented stimulus measures and signs of a
plateau in new COVID-19 cases in many parts of the world.
"We are in the hope mode regarding the rebound that will
come once the economies reopen," said Jim McDonald, chief
investment strategist for Northern Trust in Chicago.
However, many market experts have warned the rally could be
tested amid a risk of another wave of virus infections and with
growing evidence of the damage to the economy and corporate
America.
Data on Tuesday showed the domestic services sector recorded
its first contraction in nearly 10-1/2-years, while the
Institute for Supply Management's (ISM) non-manufacturing index
showed a smaller-than-expected decline. Investors are now bracing for data on the labor market
through the week with expectations of another staggering initial
jobless claims reading on Wednesday and nonfarm payrolls for the
month of April due Friday.
"It's all about the mood swings and hopes of the economies
reopening. But the problem is this could change once we get to
see some of the hard numbers, especially the employment report,"
said Peter Cardillo, chief market economist at Spartan Capital
Securities in New York.
At 12:51 p.m. ET the Dow Jones Industrial Average .DJI was
up 339.42 points, or 1.43%, at 24,089.18, the S&P 500 .SPX was
up 47.99 points, or 1.69%, at 2,890.73 and the Nasdaq Composite
.IXIC was up 161.46 points, or 1.85%, at 8,872.18.
Advancing issues outnumbered decliners for a 3.17-to-1 ratio
on the NYSE and a 2.54-to-1 ratio on the Nasdaq.
The S&P index recorded eight new 52-week highs and no new
low, while the Nasdaq recorded 41 new highs and four new lows.
