All filings by Chen Hongbing on record concern China Medical System Holdings Ltd. Between 12 September 2017 and 16 June 2025, the trades on record add up to 6 filings.

Both buying and selling appear: 4 purchases worth €4.4M, against 2 sales worth €47.4M. On balance, insiders were net sellers of €43.0M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Since January 2025: no purchases and 1 sale on the market.

A typical purchase (the median) is worth €796k. Of 4 purchases, 4 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. After 4 purchases with a full 90-day history, the hit rate stands at 100% and the median 90-day move at +104.2%. Past outcomes like these are no guarantee of what comes next.

The record was last updated on 18 June 2025 with an open-market sale (€3.8M) in China Medical System Holdings Ltd. The last purchase on record was published on 18 December 2020, which is 2,137 days ago. Most trades are made public on the day they happen. The shorter that gap, the sooner other investors can see what insiders have done. These figures are compiled from regulatory filings published by HKEX. They describe what insiders did and are not a recommendation.
