Michael J. Zimmerman

Michael J. Zimmerman is a declared insider at 6 companies (board member); the most frequent names are Stifel Financial Corp, Financial Federal Corp and Overseas Shipholding Group Inc. Over a trading history stretching from 2 January 2006 to 6 June 2025, the count stands at 57 filings.

In open-market terms, that means 10 purchases worth €482k on one side and 13 sales worth €1.3M on the other. On balance, insiders were net sellers of €773k. 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 14 share grants and 17 option exercises. So far in 2025, the count stands at no purchases and 2 sales.

In size, the median ticket on the buying side is €33k.

On 6 June 2025 came the latest disclosure, an open-market sale for €421k in Stifel Financial Corp. The most recent open-market purchase was published on 7 November 2018, 2,923 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. For comparison, the SEC allows two business days to file a 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.
