Luoyang Jianlong Micro-nano New Material Co., Ltd: what insiders have been doing
Luoyang Jianlong Micro-nano New Material 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 26 October 2026, brought 3 filings signed by 2 insiders.
The flow runs one way only: 3 sales worth €19k, from 2 insiders, and no purchase. 郭艳霞 filed the largest sale, €8,858, on 19 January 2026.
Most trades are made public on the day they happen. That lag is the time during which only the insider knows about the trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.
Across the 515 companies tracked on its exchange, the median is 2 filings; at 3 filings, this issuer sits above that mark. Over the whole record (from 2022), the tally stands at 1 purchase and 18 sales.
Elsewhere in the same sector, our signals recently picked up insider purchases at Culp Inc. This summary is built from SSE / SZSE (CSRC) disclosures alone and does not predict where the share price will go.
