Hang Seng Indexes Company, the compiler of the Hang Seng Index, has left the composition of its benchmark gauge unchanged in its latest quarterly review, while adjusting the technology and enterprises indices that track mainland Chinese tech and industrial companies.
The number of stocks on the Hang Seng Index remained at 83, according to a statement from the index compiler on Friday.
The compiler said it was adding music streaming provider Tencent Music Entertainment Group and smart driving solutions provider Horizon Robotics to the 30-member Hang Seng Tech Index, replacing investment holding company East Buy Holdings and insurer ZhongAn Online P&C Insurance.
