Ownership

Coming soon

Who actually holds the stock (institutions, funds, insiders) and how that ownership has shifted. None of this is in the marts yet, so the tab is parked until the source data lands.

What this page will show

Top 10 institutional holders from 13F filings with QoQ change
Recent insider transactions (Form 4): buys, sells, option exercises
Float concentration: what share of the float sits in the top holders
Fund flows in and out of major ETFs holding this name

We'll wire this up once the underlying data is in the marts. In the meantime, the Overview page covers the daily snapshot.
