코스나인: what insiders have been doing
코스나인, classified in the Chemicals sector, is a listed company. Its insiders report their share dealings to DART (FSS). 1 insider has disclosed 1 filing since 2 November 2025.
Not one of the filings records a straightforward purchase or sale on the market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.
For context, the typical company on the same exchange (median of 2,655 companies) published 7 filings over the same period, against 1 filing here. Looking back to 2021, when coverage begins, insiders filed 26 purchases and 4 sales.
No insider has bought 코스나인 shares on the open market in the past twelve months.
Other companies in the same sector with recent insider buying flagged by our signals: Symrise AG and Titan. This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
