Ronald William Thiessen: trading record in brief
This profile gathers the share dealings of Ronald William Thiessen in Northern Dynasty Minerals Ltd. In total, 26 filings cover trades dated from 10 September 2002 to 19 May 2026.
Both buying and selling appear: 1 purchase worth €27k, against 7 sales worth €1.5M. The net balance comes to €1.4M on the selling side. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The rest of the record consists of 1 share grant and 6 option exercises.
The latest filing, published on 21 May 2026, reports a share grant in Northern Dynasty Minerals Ltd. The last purchase on record was published on 5 March 2020, which is 2,440 days ago. The median gap between a trade and its publication by SEDI is 3 days. This delay matters because a trade only becomes useful information once it is public. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SEDI and describes the past, not future prices; it is not investment advice.
