Alibaba (NYSE: BABA) soared by as much as 9% in Hong Kong, its biggest gain in nearly three months, after a record $2.8 billion fine on the tech giant removed a months-long regulatory overhang. While analysts were quick to point out that the penalty would have limited impact on operations, concerns remained over whether this could spell further woes for the sector. Alibaba Group Holding Ltd. said Monday that it would invest in measures to support merchants on its platform, two days after China's antitrust regulator imposed a record fine against the company.
