NEW YORK, Oct 18 (Reuters) - The Dow Jones Industrial Average closed above 23,000 for the first time on Wednesday, driven by a jump in IBM after it hinted at a return to revenue growth.
The Dow hit 22,000 on Aug. 2, only 54 trading days earlier and roughly half the time it took the index to move from 21,000 to 22,000. This marks the fourth time this year the Dow has reached a 1,000-point milestone.
The index is up 3.4 percent so far in October and is on track for a seventh consecutive month of gains. For a factbox, see
