How to read this
Buy pressure is the share of open-market dollar activity that is buying (buys ÷ buys + sells). Because insiders sell far more than they buy overall, each bar is shown relative to the market-wide average so the chart reads as rotation — which sectors insiders are leaning into versus pulling out of — rather than a wall of selling. Only genuine common-stock open-market trades (SEC codes P and S) are counted; debt, preferred and derivatives are excluded, and the same block reported by several owners in a chain is counted once. A single trade above $1B with no reported holding is treated as share-count garbage and excluded. Companies are grouped into 13 sectors by their SEC SIC code, plus an "Other / Unclassified" bucket (shown but never ranked).
