NEW YORK (Reuters) - Wall Street ended the week on a sour note on Friday, with major indexes slipping modestly as investors weighed the fate of the Republicans' tax overhaul plan.
Investors have been hopeful that a tax bill under debate in Congress will boost corporate earnings and further fuel the stock market's record-setting run.
Congressional Republicans took important steps on Thursday toward the biggest U.S. tax-code overhaul since the 1980s, with the House of Representatives approving a broad package of tax cuts. The debate shifts to the Senate, where a bill has already encountered resistance within the Republican ranks.
A Reuters poll showed that nearly two-thirds of more than 60 economists said they were not confident the Trump administration would get the legislation passed this year.
"I think there is a fear that they are not going to be able to get enough support to really get something on the president’s desk to sign," said Jake Dollarhide, chief executive officer of Longbow Asset Management in Tulsa, Oklahoma.
“The week started with a lot of optimism for tax reform and I think we are ending the week a little hung over,” Dollarhide said.
