About Webb-site Legacy

What Webb-site Legacy is

Webb-site Legacy is a search and analysis tool for Hong Kong SFC licensed institutions, their responsible officers and representatives, CCASS shareholding, significant changes, and ownership concentration. It continues the Webb-site tradition originally maintained by David Webb by making public Hong Kong financial-market information easier to find, compare, and examine. The product is operated by QizAI at webbsite.hk.

The site is intended for users who need to investigate public records across several related areas. These include intermediary licensing, officer movements, listed-company ownership, participant positions, changes over time, and indicators of concentrated holdings. Results should be understood as dated public-data records rather than as a substitute for an official register or a user's own due diligence.

What you can do on the site

• Search licensed institutions by name or licence number.
• Look up an officer's licensing history and movement, including an officer licensing history view where records are available.
• View a company's CCASS top-25 holdings and recent changes.
• Set concentration and drift alerts for selected records or companies.
• Compare records across dates to identify changes in institutions, officers, holdings, or ownership concentration.
• Follow links to the relevant source or legal notice when additional verification is required.

Where the data comes from

We aggregate public information from Hong Kong's principal financial regulators and statutory bodies. All sources are refreshed daily.

Methodology

Alerts are generated by comparing newly ingested records with earlier observations and flagging material changes according to the selected company, participant, officer, concentration, or drift criteria. Where source dates are available, the result identifies the observation date so users can distinguish a new change from a delayed or corrected record.

Concentration is summarised using the holdings available for the selected company and period. HHI is computed by adding the squared ownership shares of the included holders, which gives greater weight to large positions; the covered-holder set and any exclusions are stated with the result. Officer-role mapping connects names to the SFC role and licence records available for the relevant period, while preserving uncertainty where the records do not establish a definitive identity or movement.

The displayed result may depend on the completeness, timing, naming conventions, and correction history of the underlying public sources. A missing record does not necessarily establish that an event did not occur, and a change shown on the site should be checked against the relevant official source before use.
