Live Stock Market Updates During the Coronavirus Pandemic

Stocks slide as infections rise and some states backtrack on reopening.

Stocks tumbled on Wednesday, erasing back to back gains from earlier in the week, as investors were confronted by new signs of the coronavirus pandemic’s persistence.

The S&P 500 fell more than 2 percent, with shares of retailers, airlines and cruise companies — which are proxies for sentiment about the return to normal — faring poorly.

Nervousness about the economic outlook was evident in other financial markets: Oil prices fell more than 6 percent, and U.S. Treasury bonds and gold futures were higher.

German officials this week reimposed local lockdowns after an outbreak at a slaughterhouse infected more than 1,500 people. In the United States, a surge in new cases in states including Florida, Texas and Arizona have prompted new warnings about the dangers of the pandemic.

Wednesday’s decline followed back-to-back gains on Wall Street that had lifted the Nasdaq composite to a record high. Led by large technology stocks like Apple and Amazon, the Nasdaq has outpaced the broader market in recent days, but it was also sharply lower on Wednesday.

A broad-based rise in prices never materialized, however, and gold prices spent much of the last decade tumbling.

Before new surge in virus cases, gasoline demand was recovering.

Demand for gasoline is a proxy for economic activity, and the recent surge in coronavirus cases in states like Arizona, Florida and Texas could stem a rise in gas prices.

In Texas, the second-most populous state, prices could fall sharply after Gov. Greg Abbott on Tuesday urged people to stay at home to reduce the spread of the virus.

Demand for gasoline has recovered more than half of the drop it suffered when the coronavirus spread widely in April and many states and cities ordered people to stay at home and businesses to shut down, IHS Markit, a consulting and research firm said on Wednesday.

A survey of 15,000 gasoline stations by IHS taken before the new spike in cases found that use of gasoline was down about 22 percent in the second week of June compared to the same week a year ago. That’s a stark improvement over the second week of April, when gas purchases were down nearly 50 percent.

So far this year, gasoline sales have fallen the most in the Northeast, where the pandemic spread widely in March and April, causing tens of thousands of deaths. Demand is down by about a third in Massachusetts. By comparison, sales are down about 26 percent in California.

The average price for regular gasoline nationwide on Wednesday was $2.16 a gallon, down from $2.66 a year earlier, according to AAA. Prices at the pump have been rising in recent weeks. Oil prices remain roughly a third below at the start of the year.

“We can see a new preference for driving your car instead of public transportation or a short-range flight, and people do want to get out,” said Tom Kloza, global head of energy analysis at IHS’s Oil Price Information Service. “But that will be offset by less commuting and more working from home, the cancellation of sporting events, still-high unemployment levels and possibly a second wave of the virus in the autumn.”

I.M.F. predicts deeper global downturn even as economies reopen.

As the coronavirus continues to dismantle livelihoods across the country, advisers can expect family financial dramas to keep surfacing, according to a new survey from Commonwealth, a nonprofit group that researches financial opportunities and security for the financially vulnerable.

Over the past several years, hospitals began to play innkeeper to open the door to more elective surgery, which is the lifeblood of their revenue.
