John Bernard Payne

John Bernard Payne has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Nexvet Biopharma plc and Zivo Bioscience, Inc. The record holds 14 filings, for trades running from 18 May 2015 to 26 January 2026.

The open-market record is one-sided, with 5 purchases worth €197k and not one sale. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 1 share grant and 6 option exercises. 2026 to date brings 1 purchase and no sales.

In size, the median ticket on the buying side is €20k. On 4 out of 5 purchases, another insider of the same company was buying within the same 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. For 5 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 60% of cases, with a median move of +12.5%. This is a record of the past, not a forecast.

The newest entry dates from 28 January 2026: an open-market purchase of €84k, in Zivo Bioscience, Inc. Typically, a trade is published a median of 2 days after it takes place. US insiders must file a Form 4 within two business days of a trade. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
