NEW YORK (AP) -- Stocks ended a quiet day slightly lower on Monday as investors sat on the sidelines waiting for more clues about whether the Federal Reserve might raise interest rates next month. Energy stocks fell along with the price of crude oil.
The Dow Jones industrial average fell 8.01 points, or 0.05 percent, to 17,492.93. The Standard & Poor's 500 index fell 4.28 points, or 0.2 percent, to 2,048.04 and the Nasdaq composite lost 3.78 points, or 0.1 percent, to 4,765.78.
Investors had little news to interpret and no major economic data to analyze on Monday, so stocks traded in a very narrow range throughout the day. Roughly 3 billion shares traded hands on the New York Stock Exchange, making it one of the slowest trading days so far this year.
Several members of the Federal Reserve will be making speeches this week, which may give insight to investors on what Fed policymakers might do at their meeting in June. Minutes from the Fed's late April meeting showed that policymakers at the nation's central bank seem to believe the U.S. economy has improved enough to warrant higher interest rates.
"Very quiet today," Ryan Larson, head of U.S. equity trading at RBC Global Asset Management, wrote in response to an email query from AP. "The hesitation seems to directly related to what the Fed may or may not do come its June meeting."
Securities that bet on which way the Fed will move interest rates now show that investors believe there is a 26 percent chance that interest rates will climb.
