Insider Trading Sector Heatmap
The Lynx MI Heatmap provides a visual representation of insider trading activity across every market sector. Sized by transaction volume and colored by net sentiment (buying vs. selling), it gives you an instant snapshot of where corporate executives are putting their own money.
Reading the Heatmap
Each tile on the heatmap represents a sector or individual ticker. The size of each tile corresponds to the total dollar volume of insider transactions in the selected time period — larger tiles mean more insider activity. Color indicates the direction: green hues represent net insider buying (more purchase dollars than sale dollars), while red hues represent net insider selling. The deeper the color, the more one-sided the activity. Sectors that appear as large, deep green tiles represent areas where insiders are collectively putting significant capital to work.
You can toggle between sector-level and ticker-level views, adjust the time range from 7 days to 90 days, and filter by insider role (CEO, CFO, Director, 10% Owner). Clicking any tile drills into the individual trades that contribute to that sector's activity, linking directly to our detailed company pages with full trade breakdowns.
Why Sector Heatmaps Matter
Insiders don't trade in a vacuum. When multiple insiders across an entire sector begin purchasing shares simultaneously, it can signal sector-wide tailwinds that public market participants haven't yet priced in. Conversely, broad insider selling in a sector that appears fundamentally strong may reveal hidden risks. The heatmap makes these patterns visually obvious, turning thousands of data points into an actionable at-a-glance summary.
