The major averages rose for a third day on Thursday as investors looked past earlier jitters about the spread of the omicron Covid variant. The Dow Jones Industrial Average added 196 points, or 0.55%. The S&P 500 29 points or 0.62% and sits less than 0.2% from its record high. The Nasdaq Composite gained 131 points or 0.85%.

Thursday's gains were broad across the board, although on light volume. Bank shares were higher, along with Big Tech stocks Microsoft and Nvidia.

Helping boost sentiment were new studies suggesting that omicron has a lower risk of hospitalization than other Covid variants.

The Food and Drug Administration granted emergency use authorization for Pfizer's Covid pill, the first oral antiviral drug against the virus. The FDA also authorized Merck's antiviral pill for Covid-19 on Thursday.

All three averages are on track to end the week higher. Since Monday, the Dow has risen 1.7% and the S&P 500 has popped 2.2%. The Nasdaq Composite has rallied 2.8% this week. U.S. markets are closed Friday for the Christmas holiday.

Reopening plays like airlines and cruise lines were some of the biggest winners this week during the comeback. Carnival Corp. is up 15% since Monday. Hilton Worldwide rallied 8.6% this week.

The market rebound, which began Tuesday, follows a three-day losing streak for the major averages spurred by fears about the speed of the spread of the latest Covid-19 variant. It was the worst decline for the S&P over a three-day period since September. For the Nasdaq, it was the worst three-day stretch since May.

Economic data out Thursday morning showed a strong economy with improving labor and spending trends, but inflation at uncomfortable levels.

Jobless claims for the week ended December 18 came in about as expected at 205,000. Durable goods for November rose 2.5%, compared to the 1.5% Dow Jones estimate. Personal income and spending showed increases for November.

But on the inflation side, the Federal Reserve's closely watched core personal consumption expenditures index rose 0.6% in November from the month prior. Core PCE rose 4.7% year-over-year in November, higher than the 4.5% rate expected.
