Filings by Seth L. Kaplan span 2 companies, the busiest being Griffon Corp and Instrumentation Services Inc. In total, 47 filings cover trades dated from 17 May 2010 to 9 February 2026.

In open-market terms, that means 4 purchases worth €133k on one side and 13 sales worth €5.6M on the other. The totals do not cover 1 filing with an undisclosed amount. 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 26 share grants. 2026 to date brings no purchases and 4 sales.

In size, the median ticket on the buying side is €44k.

On 11 February 2026 came the latest disclosure, an open-market sale for €33k in Griffon Corp. The most recent open-market purchase was published on 6 December 2018, 2,878 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. For comparison, the SEC allows two business days to file a Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
