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).
