Wall Street stocks surged to another round of records Friday as earnings season kicked off amid optimism ignited by the US tax reform.

All three major indices again ended at records, with the Dow Jones Industrial Average up 0.9 percent at the closing bell to 25,801.95.

The broad-based S&P 500 jumped 0.7 percent to 2,786.13, as did the tech-rich Nasdaq Composite Index which closed at 7,261.06.
