ACM Research (Shanghai), Inc.: what insiders have been doing
This page follows insider dealings at ACM Research (Shanghai), Inc. as filed with SSE / SZSE (CSRC), a company from the Technology sector. In the past year (5 November 2025 to 5 November 2026), 6 filings came from 3 insiders.
Only sales appear on the open market, 6 sales in all totalling €3.5M, filed by 3 insiders. At €1.5M, the sale published on 8 July 2026 by 陈福平 is the largest of the period.
For context, the typical company on the same exchange (median of 514 companies) published 2 filings over the same period, against 6 filings here. Since 2024, the database holds 2 purchases and 7 sales by insiders of the company.
Publication is fast: at least half of the trades appear on SSE / SZSE (CSRC) on the same day. Until a filing is published, the market cannot know about the trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.
For comparison within the same sector, see the insider buying recorded at Basler Aktiengesellschaft and Lime Technologies AB (publ). Source: insider filings from SSE / SZSE (CSRC). Past trades are no guide to future returns.
