Dongguan Changlian New Materials Technology Co.,Ltd.: what insiders have been doing
Dongguan Changlian New Materials Technology Co.,Ltd., classified in the Chemicals sector, is a listed company. Its insiders report their share dealings to SSE / SZSE (CSRC). The last twelve months, up to 18 October 2026, brought 5 filings signed by 2 insiders.
All open-market trades in the period are sales: 5 sales worth €4.5M, by 2 insiders, with no purchase on record. Biggest ticket of the year: €1.7M, sold by 麦友攀 and made public on 26 December 2025.
Most trades are made public on the day they happen. Until a filing is published, the market cannot know about the trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
With 5 filings in twelve months, the company is more active than the median of 2 filings across the 533 companies we follow on the same exchange. Over the whole record (from 2025), the tally stands at no purchases and 5 sales.
Elsewhere in the same sector, our signals recently picked up insider purchases at Culp Inc. These figures are compiled from regulatory filings published by SSE / SZSE (CSRC). They describe what insiders did and are not a recommendation.
