David Ross Parkinson

David Ross Parkinson has filed trades across 3 companies (mainly through SEC (Form 4)), most often in ESSA Pharma Inc., Facet Biotech Corp and Cerulean Pharma Inc. Over a trading history stretching from 23 January 2009 to 9 October 2025, the count stands at 11 filings.

No open-market sale appears; the market trades are 4 purchases worth €89k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Outside the open market, there are 4 share grants.

Half of the purchases are above €17k and half below. On 3 out of 4 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.

The newest entry dates from 15 October 2025: a transaction, in ESSA Pharma Inc. The latest purchase dates back some time: it was published 1,041 days ago, on 18 December 2023. Filings reach the SEC (Form 4) feed a median of 4 days after the trade. Section 16 rules allow two business days to file each Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
