Stocks are staggering Friday after weak economic data from China has investors worrying about the global economy again, and more in Friday’s Stock Market Update. Mounting tensions in Europe over Britain’s impeding departure from the European Union also darkened traders’ moods.

The Dow Jones Industrial Average dropped as much as 549 points. The benchmark S&P 500 index is falling to an eight-month low, with health care companies taking the worst losses.

Johnson & Johnson plunged after Reuters reported that the company has known since the 1970s that its talc baby powder sometimes contained carcinogenic asbestos, a claim the company denied.


KEEPING SCORE: The S&P 500 index lost 50 points, or 1.9 percent, to 2,600 at closing time. The Dow retreated 495 points, or 2.0 percent, to 24,102.

The Nasdaq composite slid 159 points, or 2.3 percent, to 6,910. The Russell 2000 index of smaller-company stocks fell 24 points, or 1.7 percent, to 1,408.

December is typically the best month of the year for stocks and Wall Street usually looks forward to a “Santa Claus rally” that adds to the year’s gains. This month, however, the S&P 500 is down 5.8 percent. That followed a small gain in November and a steep 6.9 percent drop in October.

J&J PLUNGES: Johnson & Johnson dropped 10.1 percent to $132.90 in very heavy trading, which put the stalwart company on pace for its biggest loss in 16 years. Its market value fell by $37 billion. Other health care companies also fell. Pfizer lost 2.2 percent to $43.60 while biotech drugmaker Amgen gave up 2.8 percent to $166.11.

Reuters reported that court documents and test results show Johnson & Johnson has known for decades that its raw talc and finished Baby Powder sometimes contained asbestos, but that the company didn’t inform regulators or the public. The company called the story “false and inflammatory.”

In July the company lost a lawsuit from plaintiffs who argued that its products were linked to cases of ovarian cancer and mesothelioma. A St. Louis jury awarded plaintiffs $4.7 billion. Johnson & Johnson faces thousands of other lawsuits.

SLOWING GROWTH: China’s government said industrial output and retail sales both slowed in November. That could be another sign that China’s trade dispute with the U.S. and tighter lending conditions are chilling its economy. For more than 20 years, China has been one of the biggest contributors to growth in the global economy, and when investors see signs the Chinese economy is weakening, they expect it will affect other countries like the U.S. that sell things to China.

China also announced a 90-day suspension of tariff increases on U.S. cars, trucks and auto imports. It’s part of a cease-fire that the Chinese and U.S. governments announced earlier this month to give them time to work on other aspects of the trade dispute.

Among technology companies, Apple dipped 2.8 percent to $166.15 and Cisco Systems fell 3.7 percent to $45.71. Adobe skidded 6.7 percent to $231.42 after its fourth-quarter profit disappointed investors and it also forecast lower-than-expected earnings in the current fiscal year. Industrial companies sank as well. Boeing lost 2.5 percent to $317.19.

BREXIT TROUBLES: European Union leaders rejected British Prime Minister Theresa May’s request to make changes to their deal covering Britain’s departure from the EU on March 29. British legislators aren’t satisfied with the terms May negotiated, and she canceled a scheduled vote earlier this week because it was clear Parliament wouldn’t approve it. Britain’s economy and financial markets across Europe face severe disruption without an agreement.

European bond prices rose and yields fell. Both the British pound and the euro weakened. The pound slipped to $1.2581 from $1.2660 and the euro fell to $1.1305 from $1.1367.

ENERGY: Oil prices again turned lower, as a slower global economy would weaken demand for oil and other fuels. Benchmark U.S. crude fell 2.6 percent to $51.20 a barrel in New York. Brent crude, used to price international oils, dropped 1.9 percent to settle at $60.28 a barrel in London.

Wholesale gasoline lost 3 percent to $1.43 a gallon. Heating oil fell 1.7 percent to $1.85 a gallon and natural gas dropped 7.2 percent to $3.83 per 1,000 cubic feet.

Energy companies also sagged. Exxon Mobil fell 2.3 percent to $75.18 and Schlumberger fell 5.3 percent to $38.86.

OVERSEAS STOCK MARKET UPDATE: Germany’s DAX declined 0.5 percent and the CAC 40 in France declined 0.8 percent. Britain’s FTSE 100 fell 0.5 percent.

Japan’s Nikkei 225 index slid 2 percent and the Kospi in South Korea lost 1.3 percent. Hong Kong’s Hang Seng was down 1.6 percent.

PAYING THE COST: Wholesale club company Costco also dropped following its quarter report, as the stock lost 8.6 percent to $207.12. Analysts said Costco’s profit margins weren’t as strong as they expected, and other companies that sell household goods, like Walgreens and Pepsi, also stumbled.

BONDS: Bond prices edged higher. The yield on the 10-year Treasury note fell to 2.89 percent 2.90 percent.

METALS: Gold fell 0.5 percent to $1,241.40 an ounce. Silver dipped 1.5 percent to $14.64 an ounce. Copper was little changed at $2.77 a pound.

DOLLAR DOWN: The dollar fell to 113.23 yen from 113.60 yen.
