S&K Polytec Co., Ltd.: what insiders have been doing
Every trade that managers of S&K Polytec Co., Ltd. disclose to DART (FSS) is tracked on this page. The company sits in the Industrials sector. Over the twelve months to 18 October 2026, 5 filings were filed, from 3 insiders.
The record shows 2 purchases on the open market worth €7.0M, made by 1 insider, against 3 sales worth €7.0M by 2 insiders. The amount is not disclosed for 3 filings. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. 강원형 filed the largest sale, €7.0M, on 30 March 2026, which represents 50.0% of the company's market value.
The clock since the last published purchase (30 March 2026) now reads 202 days. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.
For context, the typical company on the same exchange (median of 2,646 companies) published 7 filings over the same period, against 5 filings here. Looking back to 2021, when coverage begins, insiders filed 2 purchases and 3 sales.
Other companies in the same sector with recent insider buying flagged by our signals: Tennant Co and Butler National Corp. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
