Ping An Asset Management Co., a unit of the insurer, bought 10.8 million shares of HSBC on Wednesday, according to a Hong Kong stock exchange filing on Friday. That brings the group’s stake to 8% from 7.95% previously. BlackRock Inc., the second-biggest holder, currently owns 7.14%.

HSBC’s shares have fallen to a 25-year low as pressures mount on several fronts including a potential threat to its China expansion.
