U.S. stocks are closing slightly higher Thursday, as volatility continues to be the dominant force in Wall Street’s tumultuous September. The S&P 500 was 0.3% higher after having been close to a correction earlier. The day’s headline report showed that 870,000 workers filed for unemployment claims last week, a worse number than economists expected. Investors also weighed a report on home sales that was much stronger than economists expected. Technology stocks ended up as the biggest gainers, and only health care sector stocks fell. The market’s momentum has shifted with lightning speed recently, often changing direction by the hour.

THIS IS A BREAKING NEWS UPDATE. AP’s earlier story appears below.

U.S. stocks are down in late-afternoon trading Thursday after shedding early gains as volatility continues to be the dominant force in Wall Street’s tumultuous September.

The S&P 500 was down 0.1% after swinging between a loss of 0.9% and a gain of 1.3%. The Dow Jones Industrial Average fell 31 points, or 0.1%, to 26,734, as of 3:29 p.m. Eastern time. The Nasdaq composite was 0.1% lower. Both the Dow and Nasdaq also shed gains from earlier in the day, with the Nasdaq at one point climbing 1.6%.

The market’s momentum has shifted with lightning speed recently, often changing direction by the hour. On Wednesday, the S&P 500 rose to a modest gain when trading began, only to end the day with a 2.4% slump. It’s down about 9% from its record set on Sept. 2.

Thursday’s headline report showed that 870,000 workers filed for unemployment claims last week, a worse number than economists expected. The numbers come as investors are increasingly resigned to Congress not delivering more support for the economy, as many had been expecting, after extra unemployment benefits and other stimulus expired recently.

“Inaction speaks louder than words,” Morgan Stanley strategists wrote in a report. They no longer expect Congress to approve a meaningful stimulus package before the end of the year as part of its base case.

Stocks briefly got a boost from a report showing that sales of new homes accelerated last month, contrary to economists’ expectations for a slight slowdown. Homebuilder shares were broadly higher. Losses in health care and other sectors outweighed gains in technology stocks and companies that rely on consumer spending.

Trading has been erratic on Wall Street this month, resulting in a sharp pullback for stocks. Several reasons are behind the abrupt tumble, highlighted by worries that stocks simply grew too expensive following their record-setting run through the spring and summer.

Among other concerns weighing on markets are the upcoming U.S. elections, particularly after President Donald Trump’s refusal Wednesday to commit to a peaceful transition of power if he lost, and rising tensions between the United States and China.

Layered on top of it all is the still-raging coronavirus pandemic and the threat that worsening counts around the world could lead to more business restrictions.

It’s a stark shift from late March into early this month, when the S&P 500 soared 60% and more than recovered all its earlier losses on worries about the pandemic-caused recession. Still in investors’ favor is unprecedented support from the Federal Reserve, which is holding short-term interest rates at nearly zero and buying all kinds of bonds to support markets.

But Fed Chair Jerome Powell has said several times in testimony on Capitol Hill this week that the central bank can’t prop up the economy by itself and that the recovery likely needs more help from Congress. He’s due to testify again on Thursday.

Paralyzing partisanship has prevented a Congressional renewal of aid, and the recent vacancy on the Supreme Court caused by the death of Justice Ruth Bader Ginsburg has deepened the divide.

“The market was hoping for and anticipating some form of fiscal stimulus,” said Megan Horneman, director of portfolio strategy at Verdence Capital Advisors. “But that’s taking a backseat.”

Much of the market’s weakness this month has centered on Big Tech, where critics said prices exploded too high even after accounting for the companies’ strong growth.

Amazon, Apple and others have seen their revenue continue to rise through the pandemic, as work-from-home and other trends that benefit them take deeper hold. But Amazon shares were up more than 90% for the year just a few weeks ago, for example, and they tumbled in recent weeks.

“It’s a healthy correction after a record run out of bear market territory,” Horneman said.

On Thursday, Amazon was down 0.1% after drifting between gains and losses. Other Big Tech stocks held their gains. Apple was up 0.5%, Microsoft was up 0.8% and Google’s parent company was up 0.3%.

Moves for such stocks have an outsized effect on broad indexes like the S&P 500 because they’re the largest companies in the market by value.

The yield on the 10-year Treasury fell to 0.66% from 0.67% late Wednesday.

In Europe, Germany’s DAX fell 0.3% and France’s CAC 40 fell 0.8%. The FTSE 100 in London slid 1.3%.

In Asia, Japan’s Nikkei 225 fell 1.1%, South Korea’s Kospi tumbled 2.6% and Hong Kong’s Hang Seng dropped 1.8%. Stocks in Shanghai lost 1.7%.
