Protia Inc.: what insiders have been doing
This page follows insider dealings at Protia Inc. as filed with DART (FSS), a company from the Health Care sector. The last twelve months, up to 9 November 2026, brought 6 filings signed by 4 insiders.
Purchases and sales both appear in the filings: 4 purchases (4 insiders, €16k) and 2 sales (1 insider, €79k). The totals do not cover 2 filings with an undisclosed amount. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Biggest ticket of the year: €41k, sold by 최동섭 and made public on 8 April 2026 (0.10% of market cap). Among those who bought: 4 board members.
Across the 2,657 companies tracked on its exchange, the median is 7 filings; at 6 filings, this issuer sits below that mark. Since 2021, the database holds 19 purchases and 4 sales by insiders of the company.
Within a 30-day window, 2 purchases overlapped with buying by a second insider. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. The latest purchase dates back some time: it was published 213 days ago, on 10 April 2026. The median gap between a trade and its publication by DART (FSS) is 3 days. This delay matters because a trade only becomes useful information once it is public.
