U.S. markets extend week’s steep losses

Stock indexes lost early gains and closed lower Wednesday, extending the market’s losses for the week.

Major U.S. stock indexes gave up early gains and closed mostly lower Wednesday, extending the market’s heavy losses for the week.

The benchmark S&P 500 fell for the fifth straight day after swinging between a 0.6% loss and 1.7% gain. Smaller company stocks bore the brunt of the selling. The bond market continued to flash warning signs as long-term Treasury yields fell further below short-term yields.

The virus continues to spread and threatens to hurt industrial production, consumer spending, and travel. Morecasesarebeingreported in Europe and the Middle East. Health officials in the U.S.havebeenwarningAmericans to prepare for the virus.

“The market is still digesting the full impact of what the coronavirus could mean for global GDP growth and, more importantly, on earnings growth for a lot of companies,” said Nadia Lovell, U.S. equity strategist at J.P. Morgan Private Bank.

The S&P 500 index fell 0.4%. It’s on track for its biggest monthly decline since

May. The Dow Jones Industrial Average dropped 123.77 points, for a three-day loss of 2,034 points.

A modest rally in technology stocks helped nudge the Nasdaq composite to a 0.2% gain.

Smaller company stocks fell the most. The Russell 2000 index lost 1.2%.

European markets were mostly higher and Asian markets fell.

A burst of morning buying had stocks on track for modest gains, but the rally mostly faded by the end of the day, reflecting ongoing concerns among investors about the new coronavirus.

The outbreak has now infected more than 81,000 people globally and continues spreading. Brazil has confirmed the first case in Latin America. Germany, France and Spain were among the European nations with growing caseloads. New cases are also being reported in several Middle Eastern nations.

U.S. cases currently total 57, and the White House has requested $2.5 billion for vaccine development, treatment and protective equipment. On Tuesday, U.S. health officials called on Americans to be prepared for the disease to spread in the United States.

Bond yields headed lower for much of the day, but then recoveredmostly.Theyieldon the 10-year Treasury inched up to 1.34% from 1.33% late Tuesday. The yield on the 3-month Treasury bill edged up to 1.51%. The inversion in the yield between the 10-year and the 3-month Treasurys is a red flag for investors because it has preceded the last seven recessions.

“The bond market is sending us some warning signals that we should pay attention to and that’s what you see playing out in the market today,” Lovell said.

Investors have been moving more money into bonds in the wake of the outbreak. Traders are concerned the global economy could slow down as the world’s secondlargest economy struggles to contain the outbreak.

“A slowdown definitely is on the horizon, but it’s transitory,” Lovell said. “I would expect economic growth to reaccelerate in the back half of the year as China starts to come online.”

Energy companies led the selling Wednesday as the price of U.S. crude oil fell 2.3%.

Cruise operators continued falling amid persistent virus fears. Norwegian Cruise Line Holdings fell 7.9%, Royal Caribbean Cruises dropped 8.1% and Carnival slid 7.5%.

Technology stocks eked out a modest gain. The tech sector was among the worst hit by sell-offs this week.
