The insider–company network graph — how to read and use it
The network graph maps the relationships hidden in the filings: who trades what. It is a bipartite graph — there are two kinds of node, insiders and companies, and every edge connects an insider to a company they traded. Insiders never link directly to other insiders, and companies never link directly to other companies; they are always connected through a shared counterpart.
How to read it
- Squares are companies (showing the company logo where available); circles are insiders (a colored monogram).
- Node size reflects the total open-market value traded — bigger nodes moved more money — and heavier nodes drift toward the center.
- An edge means that insider traded that company in the window; thicker edges carry more value.
- Edge color shows direction: green for net buying, red for net selling, neutral for mixed.
- A company surrounded by many insiders is a cluster; an insider linked to many companies is a fund or serial filer connecting them.
Two views (the mode toggle)
The buttons at the top switch what the graph is built from:
- Cross-company — insiders who traded two or more different companies, plus the companies they connect. This is the view for spotting the connective tissue: funds, family offices, and people who sit across multiple boards. The "≥ N cos" buttons raise the bar for how many distinct companies an insider must touch to appear.
- Clusters — the companies where several insiders traded the same direction (the cluster signals), plus the insiders behind each one. It is the network form of the cluster-signals table. The "≥ N ins" buttons set how many insiders a company needs to qualify as a cluster.
The time window
The 30d / 90d / 180d / 1y buttons set the trailing period the graph is built over. A shorter window is more current and sparser; a longer window accumulates more relationships and a denser graph.
Getting around
- Hover a node to focus it — its neighbors stay lit and everything else dims, with a tooltip of its totals.
- Click a node to drill into that company or insider’s full detail page.
- Drag a node to reposition it; drag the background to pan; scroll to zoom.
What it leaves out (by design)
The graph counts open-market purchases and sales of common stock only — grants, option exercises, tax withholding, and derivatives are excluded so notional option values don’t distort it. It also shows the top connectors by value rather than every filer, and because most insiders only ever trade their own company, the cross-company view is intentionally small and selective.
