Stocks rose slightly on Wednesday amid renewed vaccine optimism while traders looked for clues on additional fiscal stimulus.
The Dow Jones Industrial Average gained 73.89 points, or 0.2%, to 30,409.56. The 30-stock average eked out a record closing high. The S&P 500 climbed 0.1% to 3,732.04, and the Nasdaq Composite advanced 0.2% to close at 12,870. Wednesday marked the fourth positive session in five for both the Dow and S&P 500.
Disney rose more than 2% to lead the Dow higher. Energy and materials were the best-performing sectors in the S&P 500, jumping more than 1% each.
Wednesday's move higher came after a British regulator approved a coronavirus vaccine developed by the University of Oxford and AstraZeneca for emergency use. The approval followed the discovery of a new Covid strain in the U.K., which has also been confirmed in the U.S. AstraZeneca shares climbed 0.6%.
Wall Street also weighed the prospects of greater coronavirus relief as lawmakers continued to disagree over direct payments to Americans.
The Senate currently has no plans to vote on a bill that would increase checks to $2,000 from $600. That measure was passed by the House late Monday. However, Senate Majority Leader Mitch McConnell introduced another bill that ties the increased payments to demands from President Donald Trump on tech and the election.
Stimulus payments started to go out Tuesday evening, Treasury Secretary Steven Mnuchin said.
"While we're happy with the stimulus that we have thus far, it's likely that we're going to need additional stimulus because the rising Covid cases will likely lead to more regional lockdowns after the holidays," said Megan Horneman, director of portfolio strategy at Verdence Capital Advisors. "If that's the case, and the economic data starts to disappoint, we could see" stay-at-home names outperform again in 2021.
The number of Covid cases continues to tick higher. The U.S. is now recording at least 188,167 new cases and more than 2,250 virus-related deaths each day, based on a seven-day average calculated by CNBC using Johns Hopkins University data.
With just one trading day left in the year, the major averages were on track to end 2020 higher. The Dow is up 6.6% for the year, while the S&P 500 has gained 15.5%. But the clear year-to-date winner remains the Nasdaq Composite, which has gained 43.4%.
"We expect strong economic growth to reemerge in 2021 in the wake of headwinds from the pandemic in 2020 and the U.S.-China trade war in 2019," said Doug Rao, portfolio manager at Janus Henderson Investors.
"While leadership has thus far been narrow – limited mostly to the digital economy – we foresee a broadening recovery as vaccines are widely implemented and consumers are able to reengage with the physical economy," he added.
