Wall St ends lower

U.S stocks closed down, as Treasury prices rose in volatile trading following comments
from some Fed policymakers which downplayed worries over end of central bank's bond-buying program.

Dow Jones Industrial Average fell 139.84 points, or 0.94 per cent, to close at 14,659.56.

S&P 500 fell 19.34 points, or 1.21 per cent to 1,573.09.
Nasdaq composite fell 36.49 points, or 1.09 per cent to 3,320.76.

All key S&P sectors finished in negative territory, dragged by financials and materials.
