The Dow finished above 20,000 points for the first time Wednesday, after breaching the milestone at the open, extending a stocks rally that followed US President Donald Trump's election, which sparked hopes of pro-growth policies.

At the closing bell, the Dow Jones Industrial Average stood at 20,068.29, up 0.8 percent.

The broad-based S&P 500 also rose 0.8 percent to 2,298.44, while the tech-rich Nasdaq Composite Index jumped 1.0 percent to 5,655.93, both new records.
