Stocks fell on Friday after Chinese ride-hailing giant Didi said it would delist in New York, renewing concern about U.S.-China tensions and tech regulation, while oil headed for a sixth consecutive weekly drop on Omicron and rate hike worries. Hong Kong’s Hang Seng dropped 1.3%, dragged by big tech names. Didi ran afoul of Chinese regulators by pushing ahead with its $4.4 billion U.S. IPO in July and said on Weibo it was looking to move its listing to Hong Kong.
