NPK Co.,Ltd: what insiders have been doing
This page follows insider dealings at NPK Co.,Ltd as filed with DART (FSS), a company from the Chemicals sector. The last twelve months, up to 1 November 2026, brought 19 filings signed by 4 insiders.
No insider sold shares on the market over the period. Instead, the filings list 19 purchases totalling €155k, made by 4 insiders. The totals do not cover 11 filings with an undisclosed amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The buyers include 1 major shareholder, 1 board member and 1 senior executive. The largest single trade was a purchase of €62k by 최상건, published on 9 March 2026, equal to 0.50% of the market capitalisation.
The last purchase on record was published on 27 July 2026, which is 105 days ago. Between a trade and the moment it shows up on DART (FSS), the median delay is 6 days. Until a filing is published, the market cannot know about the trade.
With 19 filings in twelve months, the company is more active than the median of 7 filings across the 2,655 companies we follow on the same exchange. Our records for NPK Co.,Ltd go back to 2021, with 19 purchases and no sales on the open market in total.
For comparison within the same sector, see the insider buying recorded at Symrise AG and Titan. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
