Mark Culhane

This profile gathers the share dealings of Mark Culhane across 4 companies, led by DemandTec, Inc., Teradata Corp /DE/ and Callidus Software Inc. Between 14 August 2007 and 1 October 2025, the trades on record add up to 120 filings.

Both buying and selling appear: 15 purchases worth €1.4M, against 43 sales worth €6.3M. Netting one side against the other leaves €4.9M of net selling. 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 30 share grants and 19 option exercises.

The median purchase comes to €89k. On 2 out of 15 purchases, another insider of the same company was buying within the same 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

Most recently, on 3 October 2025, the filings show a share grant in Genasys Inc. The clock since the last published purchase (19 August 2024) now reads 795 days. Filings reach the SEC (Form 4) feed a median of 1 day after the trade. US insiders must file a Form 4 within two business days of a trade. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
