William Williams

William Williams is a declared insider at 2 companies; the most frequent names are BriaCell Therapeutics Corp. and Briapro Therapeutics Corp. We count 44 filings; the first trade dates from 1 November 2016 and the latest from 7 July 2026.

Every open-market trade on record is a purchase: 21 purchases worth €171k, and no sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 5 share grants and 3 option exercises.

A typical purchase (the median) is worth €4,273. None of the 21 purchases we analysed coincided with buying by another insider of the same company within 30 days.

Most recently, on 28 September 2026, the filings show a share grant in BriaCell Therapeutics Corp. The clock since the last published purchase (26 April 2021) now reads 2,004 days. Typically, a trade is published a median of 3 days after it takes place. Section 16 rules allow two business days to file each Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
