NEW YORK -- Stocks were mixed in quiet trading Monday as investors sat on the sidelines waiting to see where the Federal Reserve might move interest rates next month. Energy stocks fell along with the price of crude oil.

KEEPING SCORE: The Dow Jones industrial average rose 31 points, or 0.2 per cent, to 17,531 as of 1:50 p.m. Eastern. The Standard & Poor's 500 index rose less than a point to 2,052 and the Nasdaq composite rose nine points, or 0.2 per cent, to 4,778.

FED WATCH: Several members of the Federal Reserve will be making speeches this week, which may give insight to investors on which way interest rates might move at the Fed's meeting in June. The 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 a 26 per cent chance that interest rates will climb.
