Leslie A. Moriyama is a declared insider of Dorchester Minerals, L.P. (finance chief), with filings sourced from SEC (Form 4). We count 47 filings; the first trade dates from 16 December 2015 and the latest from 19 August 2026.

No open-market sale appears; the market trades are 18 purchases worth €1.3M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Besides market trades, the filings include 26 share grants and 3 option exercises. 2026 to date brings 1 purchase and no sales.

A typical purchase (the median) is worth €37k. On 11 out of 18 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.

On 19 August 2026 came the latest disclosure, an open-market purchase for €127k in Dorchester Minerals, L.P. The median gap between a trade and its publication by SEC (Form 4) is 2 days. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
