S&P 500

Insider Cluster-Buying

Open-market insider BUYS (SEC Form 4, code P) over the last 90 days — corporate insiders putting their own cash in, especially on weakness, is a high-conviction accumulation tell. Cluster buys (several insiders, or large $) rank highest. Open-market buying is RARE in mega-caps, so this is far richer on broad / small-cap universes. Decision-support, not advice.
