Wall Street lower after data, Dudley comments

U.S. stocks were lower in early trading on Monday after data showed a better-than-expected increase in consumer spending in August, adding to the case for an interest rate increase this year. New York Federal Reserve President William Dudley added to the expectations of an early rate increase, suggesting the central bank could pull the trigger as soon as in October. Federal Reserve Chair Janet Yellen has said she expects rates to be raised this year.
