By Josh Horwitz, Chavi Mehta 3 Min Read (Adds CEO and analyst comments, background; updates share movement) May 13 (Reuters) - China’s top e-commerce platform Alibaba Group Holding Ltd on Thursday posted its first quarterly operating loss since going public in 2014 due to a record anti-monopoly fine by the country’s market regulator. Its U.S.-listed shares fell nearly 3% in choppy trading, even as the company forecast strong 2022 revenue, betting that the pandemic-driven shift to online shopping will remain resilient. The outlook, however, was overshadowed by a regulatory crackdown in China that led to the suspension of a $37 billion IPO of its affiliate Ant Group and a $2.8 billion fine in April for anti-competitive business practices.
