The latest filing, published on 25 September 2025, reports an open-market sale of €30k in 中润光学. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SSE / SZSE (CSRC) and describes the past, not future prices; it is not investment advice.
