Notable insider buys
Updated Jun 15, 2026 · refreshed continuously from SEC EDGAR
15 pattern-breaking insider buys are flagged from the last 14 days — first-ever purchases, multi-year firsts, and personal records. Buys that break a pattern: an insider's first open-market purchase in years, their first on record, or the largest they've ever made. A routine buy says little — a behavior change says a lot. No other tracker flags these.

"On record" means within the filing history we parse for each insider (their most recent filings, typically spanning years). A "first buy since" flag requires a gap of at least two years; "largest" requires at least two prior buys to compare against. Window: trades from the last 14 days.

Frequently asked questions
Why do behavior changes matter more than routine buys?
Many insiders buy on a schedule or reinvest automatically — those purchases carry little information. But when someone who hasn't bought in four years suddenly does, or writes the biggest check of their tenure, something changed their mind. That deviation is the signal.
How do you determine "first" and "largest"?
We parse each insider's recent SEC filing history (their latest filings, typically spanning multiple years) and compare the new buy against every prior open-market purchase in it. "First on record" means no prior open-market buy appears in that history; "largest on record" means it exceeds every prior buy we found. We say "on record" rather than "ever" deliberately — very long-tenured insiders may have older filings beyond what we parse.
Should I buy when an insider does something notable?
It's context, not a directive — insiders can be wrong, early, or motivated by things you can't see. Pair these flags with the insider's track-record badge and your own research. InsiderSource is an information tool, not investment advice.
