Dec 4 (Reuters) - Wall Street was set to start the week on a bright note after the U.S. Senate passed its version of a tax overhaul bill, bringing closer to reality President Donald Trump's promise of cutting corporate taxes to spur growth.
Dow futures gained more than 200 points, while the Nasdaq and the S&P 500 futures were up about half a percent.
Some of the early gainers included bank and industrial stocks. Bank of America and JPMorgan rose more than 2 percent, while Caterpillar and Boeing gained about 1.5 percent.
"This is a positive reaction to the Senate's passage," said Randy Frederick, vice president of trading and derivatives for Charles Schwab in Austin, Texas.
The Senate on Saturday approved their version of tax bill in a narrow 51-49 vote. The Senate and House of Representatives will have to reconcile their respective versions before it becomes a law.
"That (reconciliation)can be a bit of a challenge because there are differences and the number of approvals to pass it is a little bit higher than it was for the individual two sides of the Congress," said Frederick.
The S&P 500 has risen about 18 percent this year on strong corporate earnings and solid economic growth and also on hopes that Trump's agenda of corporate tax cuts and looser regulations could come through.
At 8:31 a.m. ET (1331 GMT), Dow e-minis were up 211 points, or 0.87 percent, with 45,391 contracts changing hands.
