(Reuters) - The Dow Jones Industrial Average <.DJI> closed above 26,000 for the first time on Wednesday, just eight trading days after it ended above 25,000 for the first time.

That was the shortest time between 1,000-point milestones in the Dow's history spanning more than 100 years.

It took the index 23 trading days to get to 25,000 from the first time it closed above 24,000 on Nov. 30.

The latest milestone in the Dow came as optimism over earnings fuelled a rally in U.S. stocks on Wednesday. The Dow closed at 26,115.65, up 1.3 percent.
