Insider Activity

What it is

Form 4 insider buys and sells: see when the people who know the company best are putting their own money to work.

What it shows

SEC Form 4 insider purchases — officers, directors, and 10%+ owners buying their own stock (updates roughly every 30 minutes).

• Purchases feed — individual buys, filtered to $25K+ and non-penny names in the last 30 days.
• Cluster Buys — multiple insiders at the same company buying together; the "# Insiders" count is the conviction signal.

How to use insider activity

Track Form 4 stock purchase disclosures from corporate insiders. Filter by dollar size, spot cluster buys where multiple insiders buy the same name, and use the data as corroboration alongside unusual flow. A small dollar trade by an executive with a tiny ownership change is routine. A large ownership increase, especially at a higher share price, signals real conviction.
