Cosmo Chemical Co., Ltd.: what insiders have been doing
Cosmo Chemical Co., Ltd., classified in the Chemicals sector, is a listed company. Its insiders report their share dealings to DART (FSS). The last twelve months, up to 23 October 2026, brought 11 filings signed by 2 insiders.
Both sides are active: 2 purchases and 1 sale, from 2 insiders and 1 insider respectively. The totals do not cover 3 filings with an undisclosed amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Those buying include 1 major shareholder and 1 senior executive.
The clock since the last published purchase (15 June 2026) now reads 147 days. Filings reach the DART (FSS) feed a median of 7 days after the trade. That lag is the time during which only the insider knows about the trade.
Compared with its exchange (2,650 companies, median 7 filings), a count of 11 filings is above the norm. Over the whole record (from 2021), the tally stands at 60 purchases and 2 sales.
Other companies in the same sector with recent insider buying flagged by our signals: Heidelberg Materials AG and Titan. Source: insider filings from DART (FSS). Past trades are no guide to future returns.
