The drop to 80.3 from 84.9 in November left the index just above the nine-year low of 79.6 recorded in October, and effectively wiped out an early rally on Wall Street. By the end of the last day's trading of the year, the Dow Jones was little changed at 8341 points, up eight points, while the Nasdaq lost four points at 1335, completing a grim three calendar years of losses.
