Seoulin Bioscience Co.,Ltd.: what insiders have been doing

Every trade that managers of Seoulin Bioscience Co.,Ltd. disclose to DART (FSS) is tracked on this page. The company sits in the Health Care sector. 5 insiders have disclosed 6 filings since 1 November 2025.

Every open-market trade in the period is a purchase: 5 purchases, from 4 insiders, and not a single sale. The totals exclude 5 filings filed without an amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Those buying include 2 chief executives and 1 board member.

The latest purchase dates back some time: it was published 220 days ago, on 2 April 2026. Typically, a trade is published a median of 7 days after it takes place. That lag is the time during which only the insider knows about the trade.

Across the 2,655 companies tracked on its exchange, the median is 7 filings; at 6 filings, this issuer sits below that mark. Over the whole record (from 2021), the tally stands at 19 purchases and 1 sale.

For comparison within the same sector, see the insider buying recorded at Dynavox Group AB and UCB. These figures are compiled from regulatory filings published by DART (FSS). They describe what insiders did and are not a recommendation.
