Stock market today: Wall Street falls toward worst loss since Election Day as vaccine makers sink

NEW YORK (AP) — U.S. stocks are falling Friday toward their worst loss since Election Day as the big bump Wall Street got from last week's victory for Donald Trump and cut to interest rates by the Federal Reserve keeps fading.

The S&P 500 sank 1.1% and was heading for a losing week and its worst day since October. The Dow Jones Industrial Average was down 250 points, or 0.6%, as of 11:15 a.m. Eastern time, and the Nasdaq composite was 1.9% lower.

Makers of vaccines helped drag the market down after President-elect Donald Trump said he wants Robert F. Kennedy Jr., a prominent anti-vaccine activist, to be his Secretary of Health and Human Services. Moderna tumbled 7.4%, and Pfizer fell 3.6% amid concerns about a possible hit to profits.

Kennedy still needs confirmation from the Senate to get the job, and some analysts are skeptical about his chances because of his views on vaccines and criticism of the pharmaceutical industry.

“However, if Kennedy is confirmed, it is hard to bookend risks for investors as his views are so outside the traditional Republican health policy orthodoxy,” Raymond James analyst Chris Meekins wrote in a research note. Meekins is a former deputy assistant secretary at the department known as HHS.

“Investors may need to forget everything they thought they knew about Republicans and healthcare," he said. "Kennedy’s appointment may make it less likely traditional qualified experienced (Republican) staff will agree to join HHS, creating more uncertainty.”

The only stock in the S&P 500 to fall more than Moderna was Applied Materials, which dropped 8.5% even though it reported a stronger profit for the latest quarter than analysts expected. The provider of manufacturing equipment and services to the semiconductor industry gave a forecasted range for upcoming revenue whose midpoint was short of analysts’ expectations.

The pressure is on companies to deliver big growth, in part because their stock prices have been rising so much faster than their earnings. That’s made the broad stock market look more expensive by a range of measures, which has critics calling for at least a fade. The S&P 500 is still up more than 23% for the year and near its all-time high set a few days ago, despite this week’s weakness.

Stocks had been broadly roaring since Election Day, when Trump’s victory sent a jolt through financial markets worldwide. Investors immediately began sending up stocks of banks, smaller U.S. companies and cryptocurrencies as they laid bets on the winners coming out of Trump’s preference for higher tariffs, lower tax rates and lighter regulation.

But investors are also taking into account some of the potential downsides from Trump’s return to the White House.

Besides Friday’s hit to vaccine makers, Treasury yields have also been climbing in the bond market on both the economy’s surprising resilience and worries that Trump’s policies could spur bigger U.S. government deficits and faster inflation.

That's forced traders to recalibrate how much relief the Federal Reserve could provide for the economy next year through cuts to interest rates. The Fed earlier this month lowered its main interest rate for the second time this year, and past forecasts published by Fed officials indicated more cuts were likely to come through 2025.

Lower interest rates can act as fuel for the economy and stock market, particularly after the Fed had kept rates at a two-decade high, but they can also put upward pressure on inflation.

On Thursday, Fed Chair Jerome Powell suggested the U.S. central bank will be cautious about future decisions on interest rates. “The economy is not sending any signals that we need to be in a hurry to lower rates,” he said, though he declined to discuss how Trump’s policies could alter things.

Traders have since ratcheted back forecasts for whether the Fed will cut rates again at its meeting next month, but they still see better than a coin flip’s chance of it, according to data from CME Group.

On Friday, Treasury yields were mixed in the bond market following several reports on the economy.

One showed shoppers spent more at U.S. retailers last month than expected, another signal that the most influential force on the economy remains solid.

“Many consumers were reporting that they were putting off trips and big ticket item purchases until after the election,” according to Brian Jacobsen, chief economist at Annex Wealth Management. “Many businesses reported they were putting off capital investment due to the election. Now that the uncertainty of the outcome is behind us, we could see some decent ‘relief spending.’”

Friday’s data on retail sales, though, may not be quite as strong as it appeared. After taking away purchases of automobiles, sales at retailers were weaker last month than economists expected.

A separate report, meanwhile, showed manufacturing activity in New York state is growing strongly. That soundly beat expectations for zero growth, and it comes off October’s contraction. Some of the survey’s responses were collected after Election Day.

In the bond market, the 10-year Treasury yield rose to 4.46% from 4.44% late Thursday. The two-year yield, which more closely tracks expectations for Fed action, slipped to 4.32% from 4.36% late Thursday.

In stock markets abroad, London’s FTSE 100 fell 0.1% after data from the Office for National Statistics showed economic growth slowed to 0.1% in the July-September quarter from the 0.5% in the previous quarter. It was weaker than expected.

Tokyo’s Nikkei 225 gained 0.3% after data showed growth for Japan’s economy accelerated in the latest quarter, even as the Bank of Japan raised interest rates in July.
