Insider cluster buys
US-listed stocks with cluster-buy patterns: three or more distinct corporate insiders (officers, directors, 10%+ owners) purchasing shares in the same 30-day window. Cluster buying is among the strongest insider-trading signals in academic finance literature — significantly stronger than single-officer purchases. Most-recent clusters: TSM (30 insiders, $276K); BBD (21 insiders, $27.0M); SBLK (8 insiders, $6.9M). Data parsed from SEC Form 4 filings via EDGAR. Public view delayed 4 hours.
