GC메디아이: what insiders have been doing

GC메디아이 belongs to the Technology sector. Filings by its managers are published through DART (FSS). From 2 November 2025 to 2 November 2026, the disclosure feed for GC메디아이 logged 20 filings by 6 insiders.

The flow runs one way only: 6 insiders bought (17 purchases) and nobody sold on the market. The totals exclude 17 filings filed without an amount. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Among those who bought: 4 board members, 1 major shareholder and 1 chief executive.

Across the 2,655 companies tracked on its exchange, the median is 7 filings; at 20 filings, this issuer sits above that mark. Since 2021, the database holds 19 purchases and no sales by insiders of the company.

The latest purchase dates back some time: it was published 151 days ago, on 10 June 2026. The median gap between a trade and its publication by DART (FSS) is 4 days. The shorter that gap, the sooner other investors can see what insiders have done.

Other companies in the same sector with recent insider buying flagged by our signals: Basler Aktiengesellschaft and Lime Technologies AB (publ). These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
