PlumbFast Co., Ltd.: what insiders have been doing
This page follows insider dealings at PlumbFast Co., Ltd. as filed with DART (FSS), a company from the Chemicals sector. In the past year (10 November 2025 to 10 November 2026), 4 filings came from 2 insiders.
Purchases and sales both appear in the filings: 2 purchases (1 insider, €35k) and 1 sale (1 insider). No amount is published for 2 filings, which the totals therefore leave out. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The largest single trade was a purchase of €35k by 원연경, published on 29 May 2026. The buyers include 1 board member.
For context, the typical company on the same exchange (median of 2,630 companies) published 7 filings over the same period, against 4 filings here. Over the whole record (from 2021), the tally stands at 4 purchases and 3 sales.
The last purchase on record was published on 6 October 2026, which is 35 days ago.
Other companies in the same sector with recent insider buying flagged by our signals: Culp Inc. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
