GC Corp.: what insiders have been doing

GC Corp., classified in the Health Care sector, is a listed company. Its insiders report their share dealings to DART (FSS). The last twelve months, up to 9 November 2026, brought 16 filings signed by 12 insiders.

Both sides are active: 14 purchases worth €385k and 1 sale, from 10 insiders and 1 insider respectively. The amount is not disclosed for 13 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The largest single trade was a purchase of €347k by 허진성, published on 23 April 2026, equal to 0.12% of the market capitalisation. On the buying side, the filings list 8 senior executives, 1 major shareholder and 1 chief executive among the declarants.

Compared with its exchange (2,657 companies, median 7 filings), a count of 16 filings is above the norm. Over the whole record (from 2021), the tally stands at 28 purchases and 13 sales.

The most recent open-market purchase was published on 15 June 2026, 148 days ago. Filings reach the DART (FSS) feed a median of 42 days after the trade. The shorter that gap, the sooner other investors can see what insiders have done.

Elsewhere in the same sector, our signals recently picked up insider purchases at Dynavox Group AB and Vetoquinol SA. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
