Jeff LeBlanc: trading record in brief

Jeff LeBlanc has filed trades across 3 companies (mainly through SEC (Form 4)), most often in Greenland Mines Ltd, Cactus Acquisition Corp. 1 Ltd and WinVest Acquisition Corp. The record holds 7 filings, for trades running from 22 December 2023 to 25 August 2026.

Every open-market trade on record is a purchase: 4 purchases worth €377k, and no sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Other entries cover 3 share grants. In 2026 alone, the filings show 2 purchases and no sales.

In size, the median ticket on the buying side is €81k. 1 out of 3 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster.

On 25 August 2026 came the latest disclosure, an open-market purchase for €117k in Greenland Mines Ltd. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. For comparison, the SEC allows two business days to file a Form 4. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
