Corporate earnings season has generally surpassed Wall Street expectations, but the ongoing pandemic was a topic of discussion for nearly every major company. According to FactSet, 444 companies in the S&P 500 mentioned "Covid" in earnings calls from Sept. 15 through Nov. 17.

That number could continue to rise in the weeks ahead as not every component of the S&P 500 has reported earnings during that window. Deere, for example, is set to report next week.

BMO Capital Markets said it's expecting another year of double-digit gains in stocks in 2021. The Wall Street firm expects the S&P 500 to reach the 4,200 level by the end of 2021, which implies a 15% annual gain from BMO's 2020 price target of 3,650 and a 17% rally from where stocks sit currently.

The firm sees equities gaining amid low interest rates, unprecedented stimulus and rebounding corporate earnings. BMO has a $175 per share earnings forecast for the S&P 500, a nearly 35% jump from the pandemic depressed 2020 level.

The firm expects "interest rates to remain historically low for the foreseeable future. In addition, massive fiscal and monetary responses add another layer of strong support for continued stock market gains," BMO Capital Markets chief investment strategist Brian Belski told clients.

Treasury yields are barely lower as the markets digest the Treasury's decision to allow Fed emergency programs to expire, and there's no early action in some ETFs tied to the corporate or muni bond markets.

The Fed objected to the move and has said its programs are critical. It is highly unusual for the two guardians of the economy to be at odds with each other, particularly in a time of crisis. The five programs that were eliminated include the corporate bond facility, a municipal bond backstop, and the Main Street lending program.

ETFs representing the corporate and muni markets were barely moving ahead of the Wall Street open. The iShares iBoxx $ investment Grade Corporate Bond ETF LQD was down 0.3% on thin volume, and the iShares iBoxx $ High Yield Corporate Bond ETF HYG was down 0.1%. iShares National Muni Bond ETF MUB was not moving. The 10-year Treasury was at 0.84%.

"Although we may experience a short-term gap in some of these programs, there will be some form of continuity when we likely see a change at the Department of Treasury next year," writes Greg Faranello of AmeriVet.

Faranello describes the market action as "Very muted in general — hard to say it won't be bumpy with year end and Covid rising, but markets are in a much different place than March."

BMO's Ian Lyngen says the divide between Fed Chairman Jerome Powell and Treasury Secretary Steven Mnuchin appears to fall into the political domain. "Powell advocates extending everything over year-end to ensure against dislocations whereas Mnuchin sees functioning in the credit and muni markets as sufficient and the monies would be better used as grants/bailouts," he noted.

Pfizer and BioNTech said Friday they will seek emergency authorization from the Food and Drug Administration for their coronavirus vaccine candidate.

If the application is approved, the vaccine will likely be rolled out in phases, giving priority to health-care workers, the elderly and people with underlying health conditions.

"Filing in the U.S. represents a critical milestone in our journey to deliver a COVID-19 vaccine to the world and we now have a more complete picture of both the efficacy and safety profile of our vaccine, giving us confidence in its potential," Pfizer CEO Dr. Albert Bourla said in a statement.

Pfizer shares advanced 1.7% in the premarket and BioNTech gained 0.7%.

After counting Georgia ballots by hand, the southern state confirmed Democrat Joe Biden's win over President Donald Trump. The recount was not due to any accusations of election fraud, but rather from an audit required by new state law.

"Georgia's historic first statewide audit reaffirmed that the state's new secure paper ballot voting system accurately counted and reported results," Georgia Secretary of State Brad Raffensperger said. "This is a credit to the hard work of our county and local elections officials who moved quickly to undertake and complete such a momentous task in a short period of time."

Georgia has until Friday to certify the results.

The Treasury Department said Thursday it won't extend funding for several key Federal Reserve programs instituted in the early days of the coronavirus crisis that are set to expire at the end of the year. In a letter to Fed Chairman Jerome Powell, Treasury Secretary Steven Mnuchin asked for a 90-day extension on a handful of facilities used to keep financial markets functioning. However, Mnuchin said funding won't be extended for the Main Street Lending Program as well as two facilities used to buy corporate bonds. Fed officials responded by saying they disagreed with the move, in a rare bit of disagreement between two agencies that had worked together closely during the pandemic. The department can always reinstitute the programs later if needed, but for now the Fed will have to return the remaining $455 billion in Treasury collateral that backstopped the facilities. – Jeff Cox

The major averages posted modest gains during Thursday's session, marking the first positive day in three for the Dow, S&P 500 and Nasdaq.
