Prosperous Printing Co. Ltd.: what insiders have been doing
This page follows insider dealings at Prosperous Printing Co. Ltd. as filed with HKEX, a company from the Industrials sector. 2 insiders have disclosed 12 filings since 8 November 2025.
Purchases and sales both appear in the filings: 1 purchase (1 insider, €10k) and 11 sales (2 insiders, €428k). Netting one side against the other leaves €418k of net selling. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Among those who bought: 1 senior executive. Lam Sam Ming filed the largest sale, €249k, on 21 September 2026, which represents 21.9% of the company's market value.
Across the 1,323 companies tracked on its exchange, the median is 4 filings; at 12 filings, this issuer sits above that mark. Since 2018, the database holds 1 purchase and 12 sales by insiders of the company.
The latest purchase dates back some time: it was published 61 days ago, on 8 September 2026. Typically, a trade is published a median of 4 days after it takes place. That lag is the time during which only the insider knows about the trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.
Other companies in the same sector with recent insider buying flagged by our signals: Auroora Yhtiöt Oyj and MBB SE. Source: insider filings from HKEX. Past trades are no guide to future returns.
