Corentec Co., Ltd.: what insiders have been doing
Corentec Co., Ltd. is a Health Care company. Its directors and officers file their transactions with DART (FSS). From 9 November 2025 to 9 November 2026, the disclosure feed for Corentec Co., Ltd. logged 8 filings by 3 insiders.
The record shows 7 purchases on the open market, made by 3 insiders, against 1 sale by 1 insider. The totals exclude 8 filings filed without an 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 latest purchase dates back some time: it was published 151 days ago, on 11 June 2026. Between a trade and the moment it shows up on DART (FSS), the median delay is 7 days. This delay matters because a trade only becomes useful information once it is public.
For context, the typical company on the same exchange (median of 2,630 companies) published 7 filings over the same period, against 8 filings here. Our records for Corentec Co., Ltd. go back to 2021, with 17 purchases and 4 sales on the open market in total.
