(Reuters) - U.S. stocks ended weaker on Friday after Federal Reserve Chair Janet Yellen indicated that the central bank was poised to raise interest rates this year, in line with Wall Street's expectations.
Lackadaisical trading volume during the session ended a week of slow activity that has left many investors unconvinced that recent record-high levels are likely to last.
In a speech, Yellen said a rate hike would be warranted this year if the economy keeps improving as expected. She also said it would take several years to return to normal interest rates.
Investors have enjoyed an extended period of low volatility and steady gains, but with the Fed on track to raise rates this year and major indexes near records, the market could get a bit choppier in coming weeks.
"I think what Janet Yellen and all of the Fed officials have been doing is very carefully choreographing their move. I think this is probably the most telegraphed Fed liftoff in some time," said Bruce Zaro, chief technical strategist at Bolton Global Asset Management.
"They're concerned about the markets' reaction."
