Suntar Environmental Technology Co., Ltd.: what insiders have been doing
Suntar Environmental Technology Co., Ltd. belongs to the Chemicals sector. Filings by its managers are published through SSE / SZSE (CSRC). In the past year (5 November 2025 to 5 November 2026), 4 filings came from 2 insiders.
The flow runs one way only: 4 sales worth €631k, from 2 insiders, and no purchase. 方富林 filed the largest sale, €232k, on 10 July 2026.
Across the 514 companies tracked on its exchange, the median is 2 filings; at 4 filings, this issuer sits above that mark. The full history, which starts in 2021, counts no purchases against 9 sales.
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.
In the same sector, recent insider purchases at Symrise AG also feature in our signals. Source: insider filings from SSE / SZSE (CSRC). Past trades are no guide to future returns.
