Archie C. Black: trading record in brief
This profile gathers the share dealings of Archie C. Black across 3 companies, led by SPS Commerce Inc, Proto Labs Inc and Graco Inc. The record holds 280 filings, for trades running from 11 January 2016 to 19 May 2026.
Every open-market trade on record is a sale: 196 sales worth €93.9M. The rest of the record consists of 30 share grants and 48 option exercises.
The record was last updated on 21 May 2026 with a share grant in Proto Labs Inc. The median gap between a trade and its publication by SEC (Form 4) is 2 days. US insiders must file a Form 4 within two business days of a trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
