杨友强

All filings by 杨友强 on record concern 朗坤科技, in the capacity of chief executive. We count 3 filings; the first trade dates from 8 April 2026 and the latest from 13 May 2026.

Sales make up the whole of the open-market record (3 sales, €1.3M).

Most recently, on 13 May 2026, the filings show an open-market sale worth €332k in 朗坤科技. The median gap between trade and publication is zero days: most filings appear 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. Every figure here comes from the filings published by SSE / SZSE (CSRC) and describes the past, not future prices; it is not investment advice.
