World stock markets wavered Friday in subdued Christmas Eve trade as investors mulled receding Omicron coronavirus fears, with European bourses wrapping up early before the long holiday weekend.

Asian equities mostly rose in thin volumes after Wall Street finished its trading week Thursday with strong gains on solid economic data.

The London and Paris stock exchanges ran out of steam in a half-day session with traders somewhat wary over more possible restrictions to curb Omicron.

"Markets ... remain reticent today due to lower volumes as traders are away for a holiday period," AvaTrade analyst Naeem Aslam told AFP.

"We believe overall there is still plenty of optimism about Covid vaccines -- however, concerns are real that more restrictions may be placed ahead of New Year's Eve to curtail the spread of Covid."

Frankfurt's DAX index had shut Thursday, closing the week with a 1.0-percent gain at 15,756.31 points.

Studies indicating Omicron infections are less likely to result in hospitalisation have increased confidence that the pandemic will have less impact on the economy.

Sentiment has also been buoyed by US approval of drugs from Merck and Pfizer to add to a growing arsenal of weapons against Covid.

"Omicron is looking more like a short-term disruption to the economic outlook and not a destructive headwind that knocks the economy off its course," added OANDA analyst Edward Moya.

On Wall Street, the S&P 500 ended the last session before the long holiday weekend at a fresh record following a raft of mostly decent US economic data.

Commerce Department data showed consumer spending climbed in November, though at a slower rate, and new home sales rose.

Jobless benefit claims held steady from the prior week and orders for big-ticket manufactured goods climbed, though mostly due to aircraft.

Inflation, however, posted the biggest increase in nearly four decades, illustrating the delicate balancing act the Federal Reserve faces between reining in inflationary pressures and keeping the economic recovery on track.

Omicron "will create some slowdowns in the economy, perhaps some slowdowns of production which could add to inflation pressures in the short term," Paul Christopher, head of global market strategy at Wells Fargo Investment Institute, told Bloomberg Television, adding however that the economy would work its way through the situation.
