Stocks were on track to close higher on Thursday, Aug. 31, as hopes of tax reform contributed to broad gains.

The Dow Jones Industrial Average was up 0.16%, the S&P 500 added 0.48% and the Nasdaq gained 0.85%.

Should the S&P 500 close higher on Thursday, it would mark its fifth straight day in the green, its longest winning streak since mid-May. However, the S&P 500 was still on track to post a small monthly loss, its first since March and only the second since October 2016. 

Treasury Secretary Steven Mnuchin talked up the prospects of a major tax overhaul by the end of the year. In comments to CNBC, Mnuchin said the White House has devised a "very detailed" tax plan that is currently circulating with members of Congress. The plan will be made public by the end of September.

"It's going to go through a process and we expect the House and the Senate will get this to the president to sign this year, and we couldn't be more excited about the progress we've made," he added.

Stock markets closed sharply higher on Wednesday, Aug. 30, after President Donald Trump gave a rough outline of his vision for tax reform and called on Congress to act. In a speech in Missouri, Trump said he wanted to reduce the "crushing" tax burden by "fundamentally [reforming]" a confusing tax code. Among the few details listed, he again said he wanted to cut the corporate tax rate to 15% from 35%.

The tax cut would be part of four main goals the president said should be included in a tax overhaul: simplifying the tax code, making it more competitive with tax regimes in other countries, providing tax relief for middle-class families and encouraging U.S. companies to bring back trillions of dollars in profits "parked overseas."

National Economic Council Director Gary Cohn said earlier this month that the White House had developed a "skeleton" and that the Ways and Means Committee would need to flesh out the details.

"Once the ground is laid for tax reform, Congress will focus on getting any infrastructure plan through," said Marc Lowlicht, CEO of Opes Private Wealth Management. "While Congress is very divided on many issues, this is one in which I believe with some posturing on both sides -- between tax cuts on the Republican side and job creation especially for the working class on the Democrat side of the aisle -- they should find some common ground."
