NEW YORK, Jan 7 (Reuters) - U.S. stocks were little changed in a whipsaw session on Monday as economic worries offset gains in shares of companies that tend to weather slowdowns.
Stocks seesawed from positive to negative as fears of a recession persisted after Friday's jobs report and geopolitical concerns weighed after an incident involving U.S. Navy and Iranian ships in a major oil shipping route in the Gulf.
U.S. President George W. Bush said on Monday the U.S. economy is well positioned to withstand shocks from the housing slump, financial market turmoil and high oil prices, but continued economic expansion is not a certainty.
Shares of Boeing Co <BA.N> were the top drag on the Dow, down 3.6 percent at $82.70, as investors worried that the global economy might suffer from a U.S. slowdown. Honeywell International <HON.N>, another economic bellwether, fell 1.3 percent to $57.54.
Defensive plays lent support, however. Drug makers, such as Merck & Co <MRK.N>, and companies that make consumer staples, such as cigarette maker Altria Group Inc <MO.N>, rose.
"There's a couple of things, the jobs report and instances over the weekend with Iran and the U.S. that means you are seeing a bit of a flight to defensive names," said Bennett Gaeger, managing director at Stifel Nicolaus in Baltimore.
The Dow Jones industrial average <
> was down 15.21 points, or 0.12 percent, at 12,784.97. The Standard & Poor's 500 Index <.SPX> was down 0.71 points, or 0.05 percent, at 1,410.92. The Nasdaq Composite Index < > was down 11.10 points, or 0.44 percent, at 2,493.55.Major indexes had started the year sharply lower last week, albeit in thin volume. By Monday, most trading desks were fully staffed.
Technology shares fell, with Apple <AAPL.O> the biggest drag on the Nasdaq. Apple fell 3 percent to $174.58.
Merck shares gained 1.4 percent to $57.54 on the New York Stock Exchange, while shares of Altria, parent of cigarette maker Philip Morris USA, gained 2.5 percent to $76.80.
Eli Lilly <LLY.N> posted its biggest one-day advance in more than 2-1/2 years on news Morgan Stanley upped its recommendation on the drugmaker's stock. Its stock was up 4.5 percent to $54.12.
Utilities also gave the market support, led by FPL Group Inc <FPL.N> which gained 4 percent to $71.57.
A sharp pullback in crude oil prices <CLc1> lent some support to the broader market, but hurt shares of energy companies. Exxon Mobil <XOM.N> fell 1.8 percent to $90.44 and was the top drag on the S&P 500.
U.S. crude tumbled 2.7 percent a barrel to $95.14 on the New York Mercantile Exchange as unseasonably warm weather and worries of a looming recession in the United States, the world's top oil consumer, outweighed tensions between Iran and the United States.
The Pentagon said five Iranian boats made aggressive maneuvers and showed hostile intent against three U.S. Navy ships at the weekend in the Strait of Hormuz. Oil flows through the Strait account for roughly 40 percent of globally traded oil, according to the U.S. Energy Information Administration. (Editing by James Dalgleish)
