Top Shareholder Changes provides a daily, official overview of the largest changes in shareholder positions for equities listed on the Norwegian markets with shares registered in Euronext Securities Oslo – regardless of regulatory disclosure requirements.
The service identifies the top 50 largest end‑of‑day (EoD) ownership changes per security, highlighting significant movements in investor positions that may otherwise remain undisclosed to the market.
By leveraging the daily‑updated shareholder register, the product delivers a unique level of transparency into shifts in the shareholder base, strengthening market insight and supporting the role of public investor registers as a source of market intelligence.
Top Shareholder Changes is designed for professional users such as financial institutions, data vendors, media organizations, public authorities, and market surveillance teams seeking early visibility into material ownership movements.
