Shares on Wall Street have ended higher in choppy trading as investors cheered the prospect of more fiscal stimulus to support a pandemic-damaged US economy, with more data pointing to a slowing labour market recovery.

Trading on Wall Street this week has been driven by a flurry of reports related to developments in the stimulus talks.

US House of Representatives Speaker Nancy Pelosi reported progress in talks with the Trump administration for another round of financial aid and said legislation could be hammered out “pretty soon”.

However, White House economic adviser Larry Kudlow cautioned “significant policy differences” remained, which were unlikely to be resolved before the November 3 election.

Pelosi and Treasury Secretary Steven Mnuchin have been negotiating a relief bill near the $US2 trillion ($A2.8 trillion) mark, a sum opposed by Senate Republicans who have expressed concern about the federal deficit.

Also on Thursday, data showed the number of Americans filing for state unemployment benefits last week dropped more than expected to 787,000 but remained stubbornly high as support from fiscal stimulus faded.

The Dow Jones Industrial Average on Thursday closed 152.84 points higher, or 0.54 per cent, to 28,363.66, the S&P 500 gained 17.93 points, or 0.52 per cent, to 3,453.49 and the Nasdaq Composite added 21.31 points, or 0.19 per cent, to 11,506.01.

Energy and financials rose 4.16 per cent and 1.88 per cent, respectively, posting the steepest gains among the major S&P sectors.

Investors will monitor the final presidential debate on Thursday night (1200 AEDT on Friday) between Trump and Democratic challenger Joe Biden, who is ahead in national polls.

After the bell, shares of Gilead Sciences Inc rose 3.16 per cent after the US Food and Drug Administration in the late afternoon approved its antiviral drug Veklury, or remdesivir, for the treatment of patients with COVID-19, requiring hospitalisation.

Meanwhile, about a fifth of S&P 500 companies have reported third-quarter results, of which 84.1 per cent beat earnings estimates, according to IBES Refinitiv data.

Tesla Inc climbed 0.7 per cent after the electric-car maker reported its fifth consecutive quarterly profit on record revenue of $US8.8 billion.

Chipotle Mexican Grill Inc fell 4.8 per cent as it posted a drop in quarterly profit, hurt by higher beef prices, delivery costs and coronavirus-related expenses.

Among blue-chip companies, Coca-Cola Co gained 1.4 per cent as it beat quarterly results expectations, while chemicals maker Dow Inc fell 0.6 per cent even as it surpassed quarterly profit estimates.

Advancing issues outnumbered declining ones on the NYSE by a 1.90-to-1 ratio; on Nasdaq, a 1.68-to-1 ratio favoured advancers.

The S&P 500 posted 23 new 52-week highs and 1 new lows; the Nasdaq Composite recorded 57 new highs and 32 new lows.
