Hang Seng Indexes Company plans to expand the Hang Seng Tech Index (HSTECH) to 50 constituents and introduce “sales growth” as a criterion for selection to strengthen market representation, according to a consultation paper released on Monday. Hong Kong’s major stock index compiler proposed increasing the number of HSTECH constituents from 30 to 50, using a dual-selection framework. The top 40 stocks will be selected by market capitalisation, while the remaining 10 will be picked based on revenue growth. To maintain index investability, the selection pool will narrow from all main board-listed securities to constituents of the Hang Seng Composite LargeCap & MidCap Index. Launched in 2020, HSTECH currently tracks the 30 largest Hong Kong-listed tech companies by market capitalisation, with assets under management by investment products passively tracking the index reaching US$40.4 billion by June.
