John S. Montalbano: trading record in brief
This profile gathers the share dealings of John S. Montalbano in AbCellera Biologics Inc., where the filings describe the role as board member. Over a trading history stretching from 15 December 2020 to 18 August 2026, the count stands at 11 filings.
The open-market record is one-sided, with 11 purchases worth €1.3M and not one sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. 2026 to date brings 1 purchase and no sales.
The median purchase comes to €88k. On 5 out of 11 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 18 August 2026: an open-market purchase of €95k, in AbCellera Biologics Inc. The median gap between a trade and its publication by SEC (Form 4) is 2 days. 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.
