Jeffrey Herbert Knapp

Jeffrey Herbert Knapp (senior executive) discloses dealings in Clean Harbors Inc to SEC (Form 4). In total, 25 filings cover trades dated from 1 March 2018 to 1 December 2021.

In open-market terms, that means 1 purchase worth €15k on one side and 4 sales worth €278k on the other. On balance, insiders were net sellers of €263k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 19 share grants. In 2021 alone, the filings show no purchases and 4 sales.

Most recently, on 6 December 2021, the filings show an open-market sale worth €45k in Clean Harbors Inc. The last purchase on record was published on 7 July 2020, which is 2,316 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. 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.
