Hang Seng Index
Capitalization-weighted benchmark of the largest companies listed in Hong Kong, calculated since 1969 by a subsidiary of Hang Seng Bank. It includes many mainland Chinese firms and is the main gauge of the Hong Kong equity market.
This asset is calculated on the venue linked above — a typed relationship in the dataset, not a name that happened to match. The parties named after it (Hang Seng Indexes Company) matter to how it trades but are not entities here.
No live level is shown for this asset: our open, keyless sources cover crypto, major FX crosses, the ECB policy rate, the US 10-year yield and US CPI — index levels and commodity prices are only available from licensed vendors, and we do not publish figures we cannot source openly. What we do carry.
