NEW YORK, JULY 28 -- The stock market bounded ahead today, casting aside worries about the future and sending the Dow Jones average of 30 industrials to a record high.

The closely watched index closed at 2519.77, up 25.83 points from Monday and well above its previous record of 2510.04, set on July 17.

Some analysts said the move was born out of the market's penchant for doing exactly the opposite of what prevailing wisdom would have it do. They noted that many traders had been mired by pessimism and uncertainly in recent days, pointing out that the advance was led by a host of blue chips, while the broader market had not fared as well.

"This was a skeptic's rally," said Eugene Peroni, of Janney Montgomery Scott Inc. in Philadelphia.
