When two or more officers or directors of the same company buy their own stock on the open market within a week, that is a chorus. The SEC publishes every one of those purchases within two business days. Almost no brokerage shows you when they cluster.
Chorus reads every Form 4 as it lands, groups them by company, and tells you what makes each one unusual: whether it is a buyer's first purchase in a year, how it compares to their own typical size, how much it changed their stake, and where that company's insider buying has been before.
Every cluster, with no delay, free. The filings are public the moment the SEC posts them, so withholding them would buy nothing.
No scores, no buy signals, no predictions. Each number is computed from the filing and links back to it on sec.gov, so you can check any claim yourself.
Reading three Form 4s, finding what those people did last year, and working out how much their holdings changed takes twenty minutes. Chorus does it as the filings arrive.
