우성머티리얼스: what insiders have been doing
우성머티리얼스, classified in the Chemicals sector, is a listed company. Its insiders report their share dealings to DART (FSS). In the past year (2 November 2025 to 2 November 2026), 12 filings came from 5 insiders.
On the market, 3 insiders bought (7 purchases totalling €4,026) while 2 insiders sold (2 sales). The amount is not disclosed for 8 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Among those who bought: 1 major shareholder and 1 chief executive. One trade stands out by size: a purchase of €4,026 from 임종찬, disclosed on 29 May 2026.
Compared with its exchange (2,655 companies, median 7 filings), a count of 12 filings is above the norm. Over the whole record (from 2021), the tally stands at 27 purchases and 3 sales.
The clock since the last published purchase (29 May 2026) now reads 165 days. The median gap between a trade and its publication by DART (FSS) is 6 days. Until a filing is published, the market cannot know about the trade.
