Sector FAQ
Which sector are insiders buying the most?
Over the last 90 days, Financials had the highest share of insider buying: 20.0% of open-market insider dollar volume was purchases ($373.9M bought vs $1.50B sold). Selling dominates in every sector because insiders sell for taxes and diversification, so the buy share is the fairer comparison.
How are companies assigned to sectors?
Each company is mapped to one of the GICS-style sectors from its SEC SIC code and industry description. Sector pages list every SEC-reporting company in that sector, grouped by industry, with links to its filings, insider trades and 13F holders.
What counts as a cluster buy?
A cluster buy is when three or more officers or directors of the same company buy shares on the open market (Form 4 code P) with $250,000 or more in total within the window. Coordinated buying by several insiders historically carries more signal than a single purchase.
