The latest filing, published on 16 June 2026, reports an open-market sale in Formfactor Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. US insiders must file a Form 4 within two business days of a trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
