프로티나 Stock: price and insider trades · South Korea

Every trade that managers of 프로티나 disclose to DART (FSS) is tracked on this page. The company sits in the Health Care sector. Over the twelve months to 2 November 2026, 20 filings were filed, from 11 insiders.

Both sides are active: 17 purchases worth €619k and 1 sale, from 10 insiders and 1 insider respectively. No amount is published for 9 filings, which the totals therefore leave out. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. One trade stands out by size: a purchase of €391k from 윤태영, disclosed on 30 April 2026, or 0.17% of market capitalisation. Among those who bought: 7 board members and 2 senior executives.

For context, the typical company on the same exchange (median of 2,655 companies) published 7 filings over the same period, against 20 filings here. Looking back to 2025, when coverage begins, insiders filed 27 purchases and 4 sales.

Within a 30-day window, 9 purchases overlapped with buying by a second insider. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. The last insider purchase was made public on 30 April 2026, 193 days ago. Between a trade and the moment it shows up on DART (FSS), the median delay is 3 days. That lag is the time during which only the insider knows about the trade.

Elsewhere in the same sector, our signals recently picked up insider purchases at Dynavox Group AB and UCB. Every figure here comes from the filings published by DART (FSS) and describes the past, not future prices; it is not investment advice.
