John M. Gellert

John M. Gellert (chief executive) discloses dealings in 2 companies, chiefly Seacor Holdings Inc /NEW/ and SEACOR Marine Holdings Inc. We count 106 filings; the first trade dates from 1 March 2006 and the latest from 7 March 2026.

Market trades split into 9 purchases (€1.6M) and 25 sales (€5.4M). Sales outweigh purchases by €3.8M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 35 share grants and 22 option exercises.

A typical purchase (the median) is worth €90k. 1 out of 8 purchases came within 30 days of a purchase by at least one other insider of the same company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. Ninety days after publication, 8 purchases show a median change of -23.1%, with the price up in 38% of them. These figures describe past trades and do not predict future prices.

On 10 March 2026 came the latest disclosure, a share grant for €26k in SEACOR Marine Holdings Inc. The last insider purchase was made public on 12 August 2020, 2,279 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. The legal deadline for a Form 4 is two business days after the transaction. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
