NEW YORK, USA (AFP) — US stocks finished sharply lower yesterday after the International Monetary Fund (IMF) trimmed its global growth forecast while Germany posted a second straight day of disappointing economic data.

The Dow Jones Industrial Average tumbled 272.52 points (1.60 per cent) to 16,719.39.
