Louis J. Grabowsky

Louis J. Grabowsky, listed as board member, has filed trades across 3 companies (mainly through SEC (Form 4)), most often in Griffon Corp, Cambrex Corp and ClubCorp Holdings, Inc. Between 30 April 2015 and 18 February 2026, the trades on record add up to 37 filings.

Market trades split into 7 purchases (€494k) and 4 sales (€2.5M). On balance, insiders were net sellers of €2.0M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 20 share grants and 5 option exercises. In 2026 alone, the filings show no purchases and 1 sale.

A typical purchase (the median) is worth €32k. On 2 out of 6 purchases, another insider of the same company was buying within the same 30 days. Purchases made close together by different insiders form what is called a cluster. After 5 purchases with a full 90-day history, the hit rate stands at 60% and the median 90-day move at +0.5%. They describe history only and say nothing certain about the share price ahead.

Most recently, on 20 February 2026, the filings show a share grant in Griffon Corp. The most recent open-market purchase was published on 21 December 2021, 1,784 days ago. Filings reach the SEC (Form 4) feed a median of 1 day after the trade. For comparison, the SEC allows two business days to file a Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
