China Kingstone Mining Holdings Ltd.: what insiders have been doing
Every trade that managers of China Kingstone Mining Holdings Ltd. disclose to HKEX is tracked on this page. The company sits in the Chemicals sector. From 20 October 2025 to 20 October 2026, the disclosure feed for China Kingstone Mining Holdings Ltd. logged 6 filings by 4 insiders.
Open-market activity splits into 1 purchase and 2 sales totalling €216k; 1 insider sit on the buying side and 2 insiders on the selling side. The amount is not disclosed for 1 filing. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. At €120k, the sale published on 15 April 2026 by Zhang Cuiwei is the largest of the period (0.42% of market cap). Among those who bought: 1 senior executive.
The last insider purchase was made public on 24 October 2025, 367 days ago. Between a trade and the moment it shows up on HKEX, the median delay is 1 day. The shorter that gap, the sooner other investors can see what insiders have done. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
Across the 1,319 companies tracked on its exchange, the median is 4 filings; at 6 filings, this issuer sits above that mark. The full history, which starts in 2019, counts 13 purchases against 2 sales.
In the same sector, recent insider purchases at Fuller H B Co and Culp Inc also feature in our signals. Source: insider filings from HKEX. Past trades are no guide to future returns.
