U.S. stocks finished higher on Thursday after some companies said they would spend the savings stemming from lower corporate taxes on higher wages and new construction.
The Dow Jones industrial average rose 55.64 points to close at 24,782.29. At its session highs, it traded more than 100 points higher.
The S&P 500 gained 0.2 percent to 2,684.57, with financials and energy rising 0.9 percent and 2.1 percent, respectively. Energy is also on track to post its biggest one-week gain in more than a year.
The Nasdaq composite closed just above the flatline at 6,965.36.
NBCUniversal and CNBC parent Comcast, as well as Boeing, AT&T and Wells Fargo, announced higher pay and bonuses for workers. They also announced other spending measures. Comcast, AT&T and Wells Fargo shares climbed, while Boeing's stock slipped.

House members voted on Wednesday to pass a bill that would cut the corporate tax rate to 21 percent from 35 percent. The Senate had already passed the measure on Tuesday. President Donald Trump is widely expected to sign the bill, giving him and the Republican party a major legislative victory.
Equities have risen sharply this year with investors betting on lower corporate taxes. The S&P 500 is up 19.9 percent in 2017.
Alberto Gallo, partner at Algebris Investments, said in a note that the tax cuts "will support growth in 2018, acting as a tailwind to both consumption and capital spending."
"Tax reform may also incentivize capital spending, which gradually recovered from the lows of 2015 when profits of commodity and exporting companies were squeezed by a stronger dollar and weaker prices."
The major indexes remained close to record highs on Thursday. The Dow was just 0.4 percent below a record set Monday. The S&P 500 and Nasdaq closed 0.4 percent and 0.6 percent, respectively, below their all-time highs.
"The seasonal Santa Claus rally is at hand, and we think it will help prevent a pullback before year-end. Our sentiment readings are not yet sending a collective warning, and breakouts continue to outnumber breakdowns," said Katie Stockton, chief technical strategist at BTIG.
