Advanced Nano Products Co., Ltd.: what insiders have been doing
Advanced Nano Products Co., Ltd., classified in the Chemicals sector, is a listed company. Its insiders report their share dealings to DART (FSS). In the past year (22 October 2025 to 22 October 2026), 16 filings came from 8 insiders.
Both sides are active: 10 purchases worth €28.7M and 4 sales worth €20.1M, from 6 insiders and 4 insiders respectively. The totals exclude 8 filings filed without an amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The largest single trade was a purchase of €28.5M by 박장우, published on 27 March 2026, equal to 8.0% of the market capitalisation. The buyers include 4 board members and 1 chief executive.
With 16 filings in twelve months, the company is more active than the median of 7 filings across the 2,650 companies we follow on the same exchange. Over the whole record (from 2021), the tally stands at 18 purchases and 30 sales.
The data flag 1 purchase as part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. The last purchase on record was published on 29 September 2026, which is 41 days ago. The median gap between a trade and its publication by DART (FSS) is 7 days. That lag is the time during which only the insider knows about the trade.
