UPDATE: 11:20 a.m.

Stocks rallied to record highs on Wall Street as traders hoped that new leadership in Washington will mean more support for the economy, which is still reeling from joblessness and business closures because of the pandemic.

The S&P 500 rose 1.4% today. Joe Biden took the oath of office to become the 46th U.S. president, and has already pitched a $1.9 trillion plan to help American families and businesses.

NEW YORK >> U.S. stocks are rallying to records today on encouraging earnings reports and continued optimism that new leadership in Washington will mean more support for the struggling economy.

The S&P 500 was 1.4% higher at 3,851 in afternoon trading, topping its record closing level of 3,824.68 set earlier this month. The Dow Jones Industrial Average was up 220 points, or 0.7%, at 31,151 as of 3:13 p.m. Eastern time, and the Nasdaq composite was 2.1% higher.

Joe Biden took the oath of office to become U.S. president, and he has a flurry of executive actions at the ready. He has also pitched a plan to pump $1.9 trillion more into the struggling economy, hoping to act quickly as his Democratic party takes control of the White House and both houses of Congress.

The hope on Wall Street is that such stimulus will help carry the economy until later this year, when more widespread COVID-19 vaccinations get daily life closer to normal. Such hopes have helped stocks and Treasury yields rise, even as the worsening pandemic digs a deeper hole for the economy. Spiraling coronavirus counts and deaths have more workers applying for unemployment benefits and shoppers feeling less confident.

“Most of Wall Street is assuming that the second half (of 2021) is when we will see pent-up demand start to show up in the economy, and that will push economic indicators higher and will likely cause a ramp up in earnings projections,” said Sam Stovall, chief investment strategist at CFRA.

The incoming Biden administration is taking control of the White House from Donald Trump, who pointed again today to the stock market’s level as validation of his work.

Trump’s preferred measure is often the Dow Jones Industrial Average, even though the S&P 500 is much more important to most workers’ 401(k) accounts. Under Trump, the Dow had an a annualized return of 11.8% from his inauguration until his last day in office, according to Ryan Detrick, chief market strategist for LPL Financial. That’s better than any Republican president since Calvin Coolidge during the roaring 1920s, but it’s not as good as the returns for Bill Clinton or Barack Obama.

Trump has said in the past that he should get credit for the stock market’s gains following his election but before his inauguration. The market got a “Trump bump” then on anticipation of lower tax rates, less regulation on companies and faster economic growth. Much of that did come to fruition, but the COVID-19 pandemic and the government’s response to it upended everything in 2020.

Gains for stocks have also been accelerating since Biden’s election, before his inauguration, on enthusiasm about COVID-19 vaccines and hopes that he and Congress can deliver more stimulus for the economy. The bump for stocks between the most recent Election Day and Biden’s inauguration is bigger than Trump’s bump before his inauguration.

“The market is up more than 13% since Election Day,” Stovall said, noting that since World War II, the S&P 500 has risen an average of 3.5% in the first 100 days of a Democratic president’s administration, versus an average gain of 0.5% when a Republican was in the White House.

Janet Yellen, Biden’s nominee to be Treasury secretary, told the Senate Finance Committee during her confirmation hearing on Tuesday that the incoming administration would focus on winning quick passage of its $1.9 trillion plan.

“More must be done,” Yellen said. “Without further action, we risk a longer, more painful recession now — and long-term scarring of the economy later.”

A better-than-expected start to earnings reporting season is also helping to lift the market today. Analysts came in with low expectations, forecasting the big companies in the S&P 500 will report a fourth straight drop in earnings per share because of the damage from the pandemic. But the vast majority of the earliest reports have managed to top forecasts.

Analysts have been expressing concerns about pricey stock values heading into the latest round of corporate earnings, but they look more reasonable amid the backdrop of historically low interest rates, said Solita Marcelli, chief investment officer, Americas, at UBS Global Wealth Management. The low rates, along with new stimulus and the continued rollout of vaccines, will likely help bolster markets and the recovery.

“We think that global growth is going to continue to pick up,” she said.

Netflix jumped 17.9% for the S&P 500’s biggest gain after it said it ended last year with more than 200 million subscribers. It also said it made more in revenue during the end of 2020 than analysts expected, though its earnings fell short of forecasts. Business is good enough for the company that it says it likely doesn’t need to borrow anymore to cover its day-to-day operations.

Companies will need to meet the market’s expectations — including for a huge rebound in profit growth through 2021 — to validate the big runs for their stock prices during 2020, even as their profits plummeted. Stocks of several companies slipped today, even though they reported stronger profits than expected. Procter & Gamble fell 1%, for example.

The yield on the 10-year Treasury rose to 1.09% from 1.07% late Tuesday.
