The Dow Jones industrial average closed above 26,000 points for the first time on Wednesday. The nation's oldest stock index rose 1.25 percent to close at 26,115. The Dow hit the 25,000 mark just over two weeks ago, making this the fastest-even thousand-point gain for the index. The Dow hit 26,000 in intraday trading on Tuesday, but dropped at the close. The new record comes in the early days of earnings season for the last quarter of 2017.
