John P. Zimmer (finance chief) discloses dealings in Core Molding Technologies Inc to SEC (Form 4). The record holds 32 filings, for trades running from 13 May 2021 to 12 May 2025.

The open-market side counts 4 purchases for €132k alongside 13 sales for €1.5M. Sales outweigh purchases by €1.4M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The rest of the record consists of 14 share grants and 1 option exercise.

Half of the purchases are above €32k and half below. Clusters matter here: 4 out of 4 purchases overlapped with buying by a colleague within 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

The newest entry dates from 15 May 2025: a share grant of €54k, in Core Molding Technologies Inc. The last insider purchase was made public on 27 June 2023, 1,209 days ago. The median gap between a trade and its publication by SEC (Form 4) is 4 days. The legal deadline for a Form 4 is two business days after the transaction. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
