나우코스: what insiders have been doing
나우코스, classified in the Chemicals sector, is a listed company. Its insiders report their share dealings to DART (FSS). From 31 October 2025 to 31 October 2026, the disclosure feed for 나우코스 logged 14 filings by 2 insiders.
No insider sold shares on the market over the period. Instead, the filings list 10 purchases totalling €642k, made by 1 insider. No amount is published for 7 filings, which the totals therefore leave out. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. 아스테리온홀딩스 filed the largest purchase, €430k, on 5 March 2026.
With 14 filings in twelve months, the company is more active than the median of 7 filings across the 2,655 companies we follow on the same exchange. Over the whole record (from 2021), the tally stands at 25 purchases and 2 sales.
The latest purchase dates back some time: it was published 172 days ago, on 22 May 2026. Filings reach the DART (FSS) feed a median of 7 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 Symrise AG and Titan. This summary is built from DART (FSS) disclosures alone and does not predict where the share price will go.
