June 5 (Reuters) - The Dow and S&P 500 eased on Friday as increasing expectations the Federal Reserve could raise rates as soon as September offset optimism over a recovery in the U.S. labor market.
Stronger-than-expected jobs data for May and a pickup in wages were the latest signs of better momentum in the economy.
Wall Street's top banks said they expect the Fed to begin raising interest rates in September, followed by another increase before the end of the year, according to a Reuters poll.
"The market is excited about stronger jobs and higher wages, but before (investors) can pop the cork of the champagne bottle, they start thinking about the hangover, which is higher interest rates," said Eric Kuby, chief investment officer at North Star Investment Management in Chicago.
"I think everyone is just waiting to see what happens when rates do start to rise."
The S&P utilities index, which includes top dividend payers that tend to fall as prospects for higher rates rise, was down 1.3 percent and among the weakest-performing sectors. The U.S. benchmark bond yield hit its highest since October.
S&P financials, which benefit from higher rates, were up 0.6 percent, among the day's best performing sectors, while the S&P energy index added 0.7 percent. Energy shares bounced with oil prices.
The Dow Jones industrial average fell 56.12 points, or 0.31 percent, to 17,849.46, the S&P 500 lost 3.01 points, or 0.14 percent, to 2,092.83 and the Nasdaq Composite added 9.33 points, or 0.18 percent, to 5,068.46.
For the week, the S&P 500 fell 0.7 percent, its second straight week of losses, the Dow was down 0.9 percent and the Nasdaq was down 0.03 percent.
The Fed has kept overnight rates near zero since December 2008 because the economic recovery has been slow. Cheap credit, however, has helped bolster the U.S. stock market.
New York Fed President William Dudley said he was concerned the economy may not be growing fast enough to absorb the slack among workers sidelined by the financial crisis. Still, Dudley said he expects the Fed would be in a position to raise rates later this year.
