Where funds and insiders agree.
Two independent smart-money datasets on one map: tracked institutions from quarterly 13F filings, and corporate insiders from Form 4 trades. Top-right = both buying; bottom-left = both selling; the off-diagonals are divergences worth a second look. Hover a point or tap through to the stock.
Point size ≈ number of tracked holders. Institutional axis = funds growing − trimming a position (latest two 13Fs); insider axis = distinct corporate insiders buying − selling (last ~90 days). Showing the 0 strongest signals.
About the cross-signal
What is the institution × insider cross-signal?
It overlays two independent datasets — quarterly 13F holdings from tracked institutions and open-market Form 4 trades from corporate insiders — to show where both groups are buying (consensus accumulation), both selling, or diverging.
How are the two axes measured?
Institutional breadth = the number of tracked funds that grew a position minus those that trimmed or exited it, diffed across each fund’s two most recent 13F filings. Insider breadth = the number of distinct corporate insiders buying minus selling on the open market over the last ~90 days.
Why is the insider side mostly selling?
Corporate insiders sell for many non-signalling reasons (option exercises, diversification, taxes), so sells are common. Open-market insider buying is rarer and generally more meaningful — which is why a stock in the top-right “both buying” quadrant stands out.
Is a divergence bearish or bullish?
It’s context. Funds accumulating while insiders sell is common and often benign; insiders buying while funds exit can flag a name the crowd has left. Treat this as a screen for further research, not a recommendation — 13F carries up to a 45-day lag.
