Source: SEC Form 4 filings. Each row links to its original filing.

Across 2012–2021, stocks where a CEO, C-suite officer, or director had recently made an open-market common-stock purchase ran about +28 bp per month above the universe average (n=34,268 stock-weeks). A historical tendency, not a prediction.

Congressional disclosures iStock trades disclosed by members of Congress for this company, by the date they were filed.iDisclosures shown as facts. A purchase “cluster” (≥2 members of Congress filing a buy within 90 days) has historically preceded modestly higher forward returns — and it persisted out-of-sample, though it roughly halved after 2021 (see below). A descriptive historical tendency, not a signal to trade and not used in our forecast. See /methodology.

As of 2026-09-16 · point-in-time by filed date

Purchase clusters · 2015–2021 (dev)+45 bp/mo vs baseline · up-rate 59.3% vs 57.3% · n=31,607 cluster ticker-weeks
Purchase clusters · 2022–2026 (out-of-sample)+32 bp/mo vs baseline · up-rate 54.0% vs 53.3% · n=27,793

A cluster = ≥2 members of Congress filing a purchase within 90 days. The historical tilt persisted after 2021 but roughly halved (+45 → +32 bp/mo forward 1-month vs the S&P 500 weekly-grid baseline).
