Institutional ownership research, one click closer.
Look up a ticker or company from the browser toolbar, pin the names you research most, reopen recent lookups, or type sn and a ticker in Chrome's address bar. Filing history, ownership context, watchlists and alerts stay on stockno.de.
Lightweight by design
The extension does not scrape the page you are viewing or read your browsing history. Pinned tickers and recent lookups stay in Chrome on your device.
Your account stays on stockno.de
Watchlists, alerts, subscriptions and research access remain in the same account you already use on the website.
Built around filing context
A Schedule 13 filing reports beneficial ownership. The extension takes you to the source-backed context instead of turning a filing into an unsupported trade claim.
Start with a ticker. Follow the evidence.
Use the extension as the short path into the same security pages, filing details and institutional ownership history available throughout stockno.de.
