The Hang Seng Index tracks major companies listed in Hong Kong. Free-float-adjusted market-cap weighting, with limits on individual weights, makes it a benchmark for the Hong Kong market.
History and development
The Hang Seng Index launched on November 24, 1969, with 33 constituents and a base date of July 31, 1964. It began as a benchmark of leading Hong Kong-listed businesses. Membership has since evolved with market expansion and changes in listed companies rather than preserving the original roster.

Comparing charts on this board
Pair the Hang Seng with Shanghai and China A50 CFD to follow how China-related news is priced in Hong Kong and the mainland. The sequence of reactions helps track where a theme is spreading.
Add the US ten-year yield. Hong Kong's dollar-linked currency framework makes US financial conditions an important backdrop. This gives separate lenses for Chinese corporate or policy news and US rate developments.
