Wall Street futures were pointing to a positive open Wednesday, Dec. 20, after the U.S. Senate passed a sweeping tax-overhaul bill in the early hours of the day.

Futures for the Dow Jones Industrial Average gained 73 points, or 3%, while futures for the S&P 500 rose 7.5 points. U.S. stocks stumbled on Tuesday, Dec. 19, after scoring new record highs during the previous session.

U.S. stock futures on Wednesday traded in contrast to European markets, which were in the red. London's FTSE 100 fell 0.12%, Germany's DAX declined 0.4% and France's CAC 40 slipped 0.4%.

The Senate passed the GOP-led tax bill early Wednesday morning by a vote of 51 to 48, along party lines.

The House of Representatives was poised to reconsider the bill on Wednesday. The House approved the bill on Tuesday, Dec. 19, but the vote will have to be repeated because of a procedural snag pointed out by Senate rules-makers.

The House vote was 227 to 203, with no Democrats supporting the bill and 12 Republicans opposed.
