HS Hyosung Advanced Materials Corporation Stock: price and insider trades · South Korea

HS Hyosung Advanced Materials Corporation, classified in the Retail sector, is a listed company. Its insiders report their share dealings to DART (FSS). In the past year (18 October 2025 to 18 October 2026), 18 filings came from 4 insiders.

On the market, 1 insider bought (13 purchases totalling €6.0M) while 1 insider sold (1 sale). The totals exclude 11 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. One trade stands out by size: a purchase of €2.9M from Hs효성, disclosed on 20 March 2026, or 0.65% of market capitalisation.

The last purchase on record was published on 5 June 2026, which is 135 days ago. The median gap between a trade and its publication by DART (FSS) is 7 days. The shorter that gap, the sooner other investors can see what insiders have done.

With 18 filings in twelve months, the company is more active than the median of 7 filings across the 2,648 companies we follow on the same exchange. Since 2021, the database holds 29 purchases and 7 sales by insiders of the company.
