What it is
Directors and officers of US listed companies must report every purchase or sale of their own company's shares to the SEC. This page counts, across the market, what share of those who traded in the last 4 weeks bought.
How to read it
Insiders buy en masse after markets fall (74% in late 2008, 70% in March 2020) and mostly sell in euphoric phases (22% in 2021). It is context: it carries no colour and does not count in the traffic light.
