James Russell Starr: trading record in brief
James Russell Starr has filed trades across 2 companies (mainly through SEDI), most often in Greenridge Exploration Inc. and Vector Science and Therapeutics Corp. (formerly OpenSesame Acquisition Corp.). Over a trading history stretching from 12 March 2024 to 11 October 2026, the count stands at 28 filings.
No open-market sale appears; the market trades are 25 purchases worth €1.2M. 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 option exercise. Since January 2026: 6 purchases and no sales on the market.
Half of the purchases are above €28k and half below. None of the 22 purchases we analysed coincided with buying by another insider of the same company within 30 days.
The latest filing, published on 16 October 2026, reports an option exercise in Vector Science and Therapeutics Corp. (formerly OpenSesame Acquisition Corp.). The most recent open-market purchase was published on 27 August 2026, 57 days ago. Most trades are made public on the day they happen. This delay matters because a trade only becomes useful information once it is public. This summary is built from SEDI disclosures alone and does not predict where the share price will go.
