GST Stock: price and insider trades · South Korea

Every trade that managers of GST disclose to DART (FSS) is tracked on this page. The company sits in the Industrials sector. Between 18 October 2025 and 18 October 2026, 10 insiders published 25 filings.

On the market, 9 insiders bought (20 purchases totalling €54.6M) while 2 insiders sold (2 sales). The totals do not cover 16 filings with an undisclosed amount. Unlike grants, an open-market purchase is paid for by the insider, at the market price. At €27.6M, the purchase published on 29 April 2026 by Fillimited is the largest of the period (5.3% of market cap). Among those who bought: 2 chief executives, 1 major shareholder and 1 board member.

In the case of 8 purchases, another manager of the company was buying within the same 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. The last insider purchase was made public on 12 October 2026, 6 days ago. The median gap between a trade and its publication by DART (FSS) is 7 days. That lag is the time during which only the insider knows about the trade.

Across the 2,629 companies tracked on its exchange, the median is 7 filings; at 25 filings, this issuer sits above that mark. Looking back to 2021, when coverage begins, insiders filed 40 purchases and 15 sales.

Other companies in the same sector with recent insider buying flagged by our signals: Tennant Co and Butler National Corp. Every figure here comes from the filings published by DART (FSS) and describes the past, not future prices; it is not investment advice.
