Jiangsu HHCK Advanced Materials Co., Ltd.: what insiders have been doing
This page follows insider dealings at Jiangsu HHCK Advanced Materials Co., Ltd. as filed with SSE / SZSE (CSRC), a company from the Technology sector. In the past year (4 November 2025 to 4 November 2026), 7 filings came from 2 insiders.
Open-market activity splits into 1 purchase totalling €7,789 and 6 sales totalling €130k; 1 insider sit on the buying side and 2 insiders on the selling side. On balance, insiders were net sellers of €122k. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. At €44k, the sale published on 24 December 2025 by 侍二增 is the largest of the period.
Compared with its exchange (517 companies, median 2 filings), a count of 7 filings is above the norm. Since 2025, the database holds 1 purchase and 6 sales by insiders of the company.
The latest purchase dates back some time: it was published 226 days ago, on 27 March 2026. Half of the filings or more reach the SSE / SZSE (CSRC) feed on the day of the trade. That lag is the time during which only the insider knows about the trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
For comparison within the same sector, see the insider buying recorded at Basler Aktiengesellschaft and Lime Technologies AB (publ). These figures are compiled from regulatory filings published by SSE / SZSE (CSRC). They describe what insiders did and are not a recommendation.
