Wall Street steadies following last week’s omicron-related slide

Wall Street is steadying itself Monday after last week’s slide prompted by the newest coronavirus variant, as investors wait for more clues about just how much damage it could do to the economy.

The S&P 500 was 1.4% higher in midday trading to recover a little more than half its drop from Friday, which was its worst since February. Other areas of the market, including bond yields and crude oil, were also recovering chunks of Friday’s knee-jerk reaction to run toward safety and away from risky investments.

With vaccines in hand—and with the benefit of a weekend to mull whether Friday’s sharp market moves were overdone—analysts said the world may be in better position to weather this newest potential wave. Plus, Friday’s tumble for markets may have been exacerbated by many professional traders taking the day off following Thanksgiving.

But while the market was steadying itself, it wasn’t returning to the full-on rally it had been on before the discovery of the variant now known as omicron. The variant appears to spread more easily, and countries around the world have put up barriers to travel in hopes of stemming it. Still to be seen is how effective vaccines currently available are for the variant, and how long it may take to develop new omicron-specific vaccines.

“There are still more questions than answers regarding the new variant,” said Ryan Detrick, chief market strategist for LPL Financial. “At the same time, we’ve been living with COVID-19 for almost 20 months now, and we’ve seen multiple variants.”

The Dow Jones industrial average was up 244 points, or 0.7%, at 35,144, as of 12:15 p.m., after fading a bit from an earlier gain of 388 points. Continuing caution in the market meant the smaller stocks in the Russell 2000 index were drifting between a small gain and loss, most recently up 0.2%.

The most powerful lift for stocks came from those that have been able to grow strongly almost regardless of the economy’s strength or pandemic’s pall. Gains for five big tech-oriented stocks—Microsoft, Tesla, Apple, Amazon and Nvidia—alone accounted for more than 40% of the S&P 500’s rise.

Moderna jumped 10.2% for the biggest gain in the S&P 500, adding onto an even bigger gain from Friday, after it said it’s testing the effectiveness of its vaccine against omicron. Its CEO said in a televised interview on ABC that it could take two to three months for a vaccine developed specifically for the variant to begin manufacturing.

Travel-related stocks started the day higher, but they fell back as more caution filtered into the market and as travel restrictions around the world remained in force. American Airlines Group was 0.2% lower, while Norwegian Cruise Line Holdings gave up 0.4%.

Some winning stocks of the pandemic, which soared again on Friday with omicron worries, gave up some of their gains. Zoom Video Communications fell 2.8%

The yield on the 10-year Treasury climbed to 1.52% from 1.49% late Friday, recovering a slice of its steep slide from 1.64% that day. It tends to rise and fall with expectations for the economy’s strength and for inflation.

The VIX, an index that measures how worried investors are about upcoming drops for the S&P 500, also eased but not by enough to return to where it was before omicron.

Besides waiting on more clues about how much economic damage omicron will ultimately do, the market has several big mileposts this week that could swing prices. The headliner is likely Friday’s jobs report, where economists expect to see an acceleration in hiring by employers during November.

Omicron adds more risk to a global economy already contending with paralyzing uncertainty. Travel bans, including recent decisions by Japan and Israel to bar foreign visitors, threaten to disrupt global business. Global supply chains already gummed up by bottlenecks could be further ensnarled if outbreaks shut down factories, ports and freight yards.

Shipping problems would risk pushing prices higher, adding to inflation pressures. In response, the world’s central banks could raise interest rates and imperil the recovery from last year’s brief but intense coronavirus recession.

“Omicron reinforces that the economy remains tethered to the pandemic,’’ Mark Zandi, chief economist at Moody’s Analytics, said on Twitter Monday. “With each new wave of the pandemic, the economy will suffer slower growth and higher inflation.’’

The U.S. economic recovery lost significant momentum when the highly contagious delta variant hit over the summer. Economic growth slowed to an annual rate of 2.1% from July through September from 6.7% from April through June and 6.3% from January through March.

Still, more Americans are vaccinated now, and the economy has shown resiliency, regaining speed after the summer slowdown. Zandi tweeted that “the most likely scenario is the economy will manage through each wave better than the one before it.’’

Of course, the only way to know which scenario will ultimately occur is to wait to see it through. And that uncertainty in the meantime could lead to more up-and-down swings for the market.
