SINGAPORE — Asia-Pacific stocks were mixed on Friday, following days of turbulent trading this week as investors continue to monitor the situation surrounding the omicron Covid variant.

Chinese tech stocks in Hong Kong plunged after ride-hailing giant Didi announced Friday that it will begin taking steps to delist from the New York Stock Exchange — less than six months after it made its debut stateside. The company also said in the statement that it will pursue a listing in Hong Kong.

Shares of Tencent in Hong Kong fell 2.32% while Alibaba dropped 2.61% and Meituan slipped 2.66%. The Hang Seng Tech index declined 1.53% to 5,925.52.

Hong Kong's broader Hang Seng index ended the trading day about 0.1% lower at 23,766.69.

Mainland Chinese stocks closed higher, with the Shanghai composite rising 0.94% to 3,607.43 while the Shenzhen component climbed 0.857% to 14,892.05.

In Japan, the Nikkei 225 closed 1% higher at 28,029.57 while the Topix index gained 1.63% to finish the trading day at 1,957.86. Shares of conglomerate SoftBank Group, which holds a sizable stake in Didi, shed 0.71%.

Stocks around the world have been swinging wildly between gains and losses for much of this week as uncertainty remains around the economic impact of the recently discovered omicron variant. As more cases of omicron are being detected globally, experts say the new strain had likely already been circulating for some time.
