About the Hang Seng
Hang Seng Indexes Company maintains the Hang Seng Index, a Hong Kong equity benchmark selected from an eligible universe using rules for listing history, market value, turnover and representation. The index combines Hong Kong companies with mainland China businesses listed in Hong Kong. Free-float and weighting limits affect how much a member contributes; selection is not a simple ranking of the largest share prices.
Constituents are reviewed quarterly. Results are generally announced in February, May, August and November, with changes taking effect in the following month, normally on the Monday after its first Friday. Announced names and effective dates can differ from a typical schedule when corporate events intervene. A record with no separately sourced announcement date should not be read as proof of a same-day decision.
The Tracker Fund of Hong Kong (2800.HK) follows this index; EWH is a broader Hong Kong equity fund, not a direct Hang Seng Index tracker. For mainland-linked shares, Stock Connect eligibility may matter to which investors can trade a name, but joining the Hang Seng Index does not itself guarantee Stock Connect inclusion. That distinction is important when interpreting trading around review dates: accessibility and index membership are separate events.

How Hang Seng additions work
Hang Seng Indexes reviews quarterly, announcing results in February, May, August and November. Changes take effect on the Monday following the first Friday of March, June, September and December. A change is announced first and only takes effect after the close on the effective date. Between those two dates, every fund tracking the index (2800.HK, EWH) has to buy the incoming stock, which is why the window matters to traders.
What happens to a stock after it joins Hang Seng
Inclusion is often described as a guaranteed pop. The tracked history is more mixed: . Returns are measured from the effective close and can also be viewed against the index itself, so a rising market doesn't get counted as an inclusion effect.
When are Hang Seng changes announced?
Quarterly review (Feb / May / Aug / Nov). Scheduled review, announcement and effective dates for the next twelve months are listed on the index review calendar. Ad hoc changes — a takeover, a bankruptcy, a fast-track promotion — are announced outside that schedule, usually with a few days' notice.
