John Tuerk appears in our data through filings on Clear Blue Technologies International Inc. shares, published by SEDI. Over a trading history stretching from 13 July 2018 to 4 August 2026, the count stands at 22 filings.

Market trades split into 5 purchases (€48k) and 4 sales (€6,546). No amount is published for 1 filing, which the totals therefore leave out. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 6 option exercises.

Half of the purchases are above €12k and half below. None of the 4 purchases we analysed coincided with buying by another insider of the same company within 30 days.

On 27 August 2026 came the latest disclosure, an option exercise in Clear Blue Technologies International Inc. The most recent open-market purchase was published on 28 July 2025, 453 days ago. Filings reach the SEDI feed a median of 6 days after the trade. The shorter that gap, the sooner other investors can see what insiders have done. Every figure here comes from the filings published by SEDI and describes the past, not future prices; it is not investment advice.
