NanJing Research Institute of Surveying, Mapping & Geotechnical Investigation,Co.Ltd.: what insiders have been doing
NanJing Research Institute of Surveying, Mapping & Geotechnical Investigation,Co.Ltd., classified in the Construction sector, is a listed company. Its insiders report their share dealings to SSE / SZSE (CSRC). In the past year (5 November 2025 to 5 November 2026), 1 filing came from 1 insider.
There is no open-market purchase to report; the filings show 1 sale worth €18k by 1 insider. At €18k, the sale published on 11 August 2026 by 刘键 is the largest of the period.
Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.
With 1 filing in twelve months, the company is quieter than the median of 2 filings across the 519 companies we follow on the same exchange. The full history, which starts in 2021, counts 2 purchases against 5 sales.
Every figure here comes from the filings published by SSE / SZSE (CSRC) and describes the past, not future prices; it is not investment advice.
