Shannon Hall: trading record in brief
Shannon Hall is a declared insider at 2 companies (board member); the most frequent names are Bio-Rad Laboratories, Inc. and Mesa Laboratories Inc /CO/. We count 28 filings; the first trade dates from 13 June 2016 and the latest from 15 August 2026.
No open-market purchase appears, only 8 sales worth €733k. The rest of the record consists of 4 share grants and 16 option exercises.
Most recently, on 17 August 2026, the filings show an option exercise in Mesa Laboratories Inc /CO/. The median gap between a trade and its publication by SEC (Form 4) is 1 day. Section 16 rules allow two business days to file each Form 4. 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.
