Tplex Co., Ltd.: what insiders have been doing
Tplex Co., Ltd., classified in the Chemicals sector, is a listed company. Its insiders report their share dealings to DART (FSS). 5 insiders have disclosed 8 filings since 6 November 2025.
On the market, 4 insiders bought (7 purchases totalling €561k) while 1 insider sold (1 sale). The totals exclude 6 filings filed without an amount. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Biggest ticket of the year: €447k, bought by 김영국 and made public on 8 May 2026 (1.2% of market cap). Among those who bought: 2 chief executives, 1 major shareholder and 1 board member.
The data flag 2 purchases as part of a group of insiders buying within 30 days of each other. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. The last purchase on record was published on 6 July 2026, which is 127 days ago. The median gap between a trade and its publication by DART (FSS) is 7 days. This delay matters because a trade only becomes useful information once it is public.
Across the 2,658 companies tracked on its exchange, the median is 7 filings; at 8 filings, this issuer sits above that mark. The full history, which starts in 2021, counts 23 purchases against 3 sales.
