태성: what insiders have been doing
This page follows insider dealings at 태성 as filed with DART (FSS), a company from the Industrials sector. 4 insiders have disclosed 8 filings since 31 October 2025.
Not one open-market sale was filed. On the buying side, 4 insiders reported 5 purchases. No amount is published for 5 filings, which the totals therefore leave out. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. On the buying side, the filings list 1 senior executive and 1 chief executive among the declarants.
For context, the typical company on the same exchange (median of 2,655 companies) published 7 filings over the same period, against 8 filings here. The full history, which starts in 2021, counts 12 purchases against 14 sales.
The clock since the last published purchase (5 March 2026) now reads 250 days. Filings reach the DART (FSS) feed a median of 4 days after the trade. This delay matters because a trade only becomes useful information once it is public.
In the same sector, recent insider purchases at Bolloré SE and Auroora Yhtiöt Oyj also feature in our signals. Source: insider filings from DART (FSS). Past trades are no guide to future returns.
