The S&P 500 fell 1.1 percent, after earlier climbing more than 1 percent, while the Nasdaq composite dropped 1.3 percent.
The market’s recent slump has come as investors parse signals from the Federal Reserve that interest rate increases are coming in 2022.
A closely watched measure of investor expectations, the yield on 10-year Treasury notes, climbed as high as 1.88 percent on Tuesday, its highest level since January 2020, before falling back to 1.83 percent on Thursday, which is still sharply higher than it was at the start of the year.
“We’re talking about markets that have become very accustomed to extensive support from central banks and very gentle unwinding when appropriate,” Craig Erlam, senior market analyst at OANDA, wrote in a note to clients on Wednesday.
On Thursday, American Airlines reported a $931 million loss in the final three months of last year, when the Omicron variant of the coronavirus forced airline workers to call in sick at record rates and problems caused by winter storms contributed to cancellations during the holiday season.
Banks have also come under pressure in recent days, as major lenders including Citigroup, Goldman Sachs and JPMorgan Chase reported lower profits for the fourth quarter.
Consumer-facing companies like Procter & Gamble and Bed Bath & Beyond have also said they are facing supply chain disruptions and higher labor and freight costs.
But, broadly speaking, technology stocks have served as a key measure of changing investor attitudes toward stocks this month.
The drop follows a big rally for tech stocks: In 2021, the Nasdaq composite rose 21.4 percent, its third-consecutive year of double-digit gains.
The number was slightly off the 8.5 million that Netflix had forecast, but the 1.2 million subscribers added from the United States and Canada region reflected its strongest quarter there since the beginning of the pandemic.
Two of Netflix’s most highly anticipated projects — the second season of “Bridgerton” and “The Adam Project,” a film starring Ryan Reynolds — will debut at the end of the quarter in March.
“I do think that they have permission to take this price increase,” said Berna Barshay, an analyst with Empire Financial Research.
Films like “Red Notice” and “Don’t Look Up” became the most-watched movies in the company’s history, according to Netflix, and returning shows like “Cobra Kai” and “The Witcher” attracted viewers as well.
The departure of Mr. Suleyman, who was Google’s vice president of product management and policy for artificial intelligence, closes a tumultuous tenure at the company.
The deal demonstrated the value of companies that specialized in “deep learning,” a form of artificial intelligence that became more important in the early part of the last decade.
He also became a key voice in DeepMind’s efforts to ensure that its technologies would not be used for military applications, which led to a clash with Google when the company joined a flagship A.I.
While at Google, Mr. Suleyman was stripped of some management responsibilities at DeepMind after the company received complaints that he bullied subordinates.
The company said on Thursday that it planned to open a clothing store called Amazon Style this year in Glendale, Calif., at a shopping center called The Americana at Brand.
Items will range in price from $10 to $400, the company said in an email, and the store will be about 30,000 square feet, which is several times larger than a typical specialty mall store.
Amazon said it planned to provide real-time recommendations to customers as they shopped, incorporating their physical browsing behavior and preferences on the Amazon Shopping app.
Amazon also said it would have new technology in fitting rooms. Customers will find additional recommendations in fitting rooms once they are ready to try on garments — something that sales associates usually do in most clothing stores.
About 17 percent said they had started their search in multi-line stores like department store chains or warehouse clubs, while 15 percent started on Google.
The pandemic upended the apparel industry and shopping centers, making Amazon’s move particularly timely.
“We look forward to engaging with the public, elected representatives and a broad range of stakeholders as we examine the positives and negatives of a central bank digital currency in the United States,” Jerome H.
Central banks from the Bahamas to Sweden and China are experimenting with digital currency offerings, fueling concerns on Capitol Hill that the Fed might fall behind the competition.
While consumers already use digital money when swiping a credit card or making online purchases, that money is actually backed by the banking sector.
Commercial banks, for their part, have been worried that the creation of a central bank digital currency and Fed accounts could take away their deposit base and upend their business model.

Omicron forced airline workers to call in sick at record rates over the holidays, compounding problems caused by winter storms and contributing to tens of thousands of cancellations during one of the year’s busiest travel periods.
25, American canceled just under 1,500 flights, compared with more than 4,300 at Southwest Airlines, more than 2,500 for United Airlines and more than 2,000 for Delta Air Lines.
The airline expects capacity, as measured by seats sold and distance flown, to be about 8 to 10 percent less in the first three months of this year than in the same period in 2019.
The company said domestic and short-distance international travel had nearly recovered to prepandemic levels, while corporate travel within the United States was about 70 percent restored.
American said on Thursday that capacity was down about 13 percent in the final three months of last year from the same period in 2019, with revenue down about 17 percent.
The airline had spent the pandemic simplifying its fleet, replacing older, expensive planes with newer, more efficient ones.
After recovering from the holiday mess last week, the industry faced another potentially major disruption this week: an expansion of 5G cellular service that airlines warned could interfere with flight safety devices.
Radio altimeters, which were developed in the 1920s and help pilots determine a jet’s altitude and its distance from other objects, use frequencies closer to the ones used by American cellular carriers’ 5G services than earlier generations.
AT&T and Verizon agreed on Tuesday to temporarily restrict 5G in a two-mile buffer zone around a number of large airports, which degrades speeds for users in those areas.
For airlines, the biggest issue is how altimeters interact with automated systems. Boeing 787s, for instance, use altimeters to control when reverse thrusters fire on landing.
“The problem here is because the F.A.A.
Elon Musk, Tesla’s chief executive, had hoped the facility, the company’s first assembly plant in Europe, would have been completed by the end of last year.
Birgit Dietze, the regional leader for the IG Metall union, which represents autoworkers in Germany, said on Thursday that a vote for 19 representatives to serve on the works council had been scheduled for Feb.
Works councils, committees that represent employees in helping to set factory policies, are standard in German companies.
Members of the state government in Brandenburg, which has not yet granted final approval for the $7 billion plant, said earlier this month that all of the necessary paperwork had been received in late December and the process was in its final stages.
“We are on what we hope are the last steps as far as the whole issue of permits for the factory,” Jörg Steinbach, Brandenburg’s minister for the economy, said last week.
IG Metall said it was concerned that the works council vote had been scheduled even though roughly only one in six of the estimated 12,000 people who are expected to work at the plant have been hired so far.
Although Tesla has opposed unions at its plants in the United States, Germany has a strong tradition of unionization, and IG Metall recently opened an office near the plant and has been answering questions from workers and those applying for jobs.
The plant, where Tesla expects to eventually produce 500,000 Model Y sport utility vehicles a year, has begun turning out cars, but they are prototypes that cannot be sold.
The news, first reported by USA Today and confirmed by NBC on Thursday, was not exactly a surprise, since the vast majority of NBC’s announcing teams for sports other than the marquee ones of figure skating and Alpine skiing were already planning to work remotely.
13 Super Bowl outside Los Angeles, and it is unclear whether he will return to Beijing for the closing ceremony on Feb.
About 250 NBC personnel are already in Beijing to work the games.
Even in the run-up to the games, the prospect of being in Beijing had worried some prominent athletes.
“It’s even being worried about getting there, as you mentioned, because I have holed myself up in this house,” Lipinski said.
In the pandemic, the apps can also help the office feel safer by communicating building-wide health information and reducing physical interactions.
Companies should be transparent about what information they are tracking, how they are using it, who will have access to it and why, Dr.
Millions of Americans are voluntarily leaving their jobs.
A booming ecosystem of highly valued, cash-rich start-ups in Silicon Valley and beyond are expanding at breakneck speed and trying to unseat stalwart companies in all kinds of fields.
The funding frenzy follows nearly two years of a pandemic when people and businesses increasingly relied on tech, creating bottomless opportunities for start-ups to exploit.
The activity has crossed into even frothier territory in recent months, as tech start-ups offering food delivery, remote-work software and telehealth services realized that they not only would survive the pandemic but were in higher demand than ever.
The big-money headlines have carried into this year.
Police officers met Flight AAL38 at Miami International Airport when it returned, and escorted a woman in her 40s off the plane, said Lea Gonzalez, a public information officer for the Miami-Dade Police Department.
As of Tuesday, the agency said, it had received 151 reports of unruly passengers, 92 related to face masks, since Jan.
