Rebounding Dow up more than 600 pts.

The Dow Jones Industrial Average soared on Thursday as investors shrugged off news of the second US case of the Omicron variant and sought to mount a comeback from the sell-off earlier this week.

The Dow surged more than 600 points, or 1.8 percent, wiping out Wednesday’s losses of 462 points and even recouping some of Tuesday’s plummet.

The S&P 500 and the Nasdaq similarly rose 1.4 percent and 0.8 percent, respectively.

The surge was broad-based and led by so-called reopening stocks like airlines, casinos, hotels and other travel sectors.

Apple was one of the few stocks in the red on Thursday after Bloomberg reported that the tech giant had told suppliers that demand for its new iPhone 13 lineup had fallen ahead of the holiday season, prompting the company to slash its production goal for the crucial year end.

The broad-based market gains came even as health officials in Minnesota announced that a resident tested positive for the Omicron variant of the coronavirus.

The man had recently attended a conference at Midtown’s Javits Center, spurring Mayor de Blasio to warn that community transmission ought to be expected in the city.
