NEW YORK, Aug 5 (Reuters) - U.S. stocks rose on Tuesday as a tumble in the price of oil tempered inflation concerns, reinforcing expectations that the Federal Reserve will keep interest rates unchanged at its meeting later in the day, despite calls for higher rates among some board members.
Shares of planemaker Boeing <BA.N> jumped almost 5 percent and were the biggest boost on the Dow industrials, as lower oil prices improved the outlook for the energy-dependent air sector.
Major manufacturers General Electric <GE.N> and Procter & Gamble <PG.N> jumped more than 2 percent, also helped by hopes that moderating inflationary pressures would increase consumer spending. GE was the biggest boost on the S&P 500.
Data from the Institute for Supply Management showing the U.S. service sector shrank less than expected in July also supported sentiment. The ISM report included a decline in the prices paid index. For details, see [
].U.S. crude oil futures <CLc1> fell as low as $118 per barrel earlier, after settling at $121.41 on Monday. Oil was trading at about $119.70 per barrel around midday.
"The factor in the market is that oil prices went down to $118 a barrel. Oil has been overwhelmingly the major single factor driving markets since late June. I think that is a completely sufficient explanation," said Brian Gendreau, investment strategist at ING Investment Management in New York.
The Dow Jones industrial average <
> gained 206.88 points, or 1.83 percent, at 11,491.03, while the Standard & Poor's 500 Index <.SPX> rose 22.32 points, or 1.79 percent, at 1,271.33. The Nasdaq Composite Index < > climbed 38.42 points, or 1.68 percent, at 2,323.98.The decline in oil prices may also help Fed Chairman Ben Bernanke keep interest rates at the current level of 2 percent for the next several months, as the credit crisis keeps the economy in check.
But analysts expect the statement accompanying the rate decision, due at around 2:15 p.m. (1815 GMT), to include slightly stronger language on inflation to satisfy more hawkish board members who have been calling for a rate increase.
Investors snapped up shares broadly, but particular strength was evident in energy-consuming sectors, including airlines and industrial companies. Shares of retailers, tech and financial services companies also gained.
GE shares rose 2.6 percent to $28.91 on the New York Stock Exchange, while shares of American International Group <AIG.N>, the world's largest insurer, jumped 7.2 percent to $28.62.
On Nasdaq, shares of iPod maker Apple Inc <AAPL.O> climbed 2.7 percent to $157.30. According to theflyonthewall.com, UBS started Apple with a "buy" rating.
Among retailers, shares of Wal-Mart Stores <WMT.N> , the world's biggest retailer, rose 2.5 percent to $59.90, while Target Corp <TGT.N> gained 4.9 percent to $47.22.
Among airlines, Continental Airlines <CAL.N> rose 8.8 percent to $15.50, as the airline index <.XAL> gained 7.34 percent.
Procter & Gamble Co <PG.N>, the world's largest consumer products maker, posted a stronger-than-expected quarterly profit. Its stock rose 2.34 percent to $67.37 on the NYSE. (Editing by Leslie Adler)
