Filings by Sum Kwong Yip, Derek span 2 companies, the busiest being Jacobson Pharma Corporation Ltd. and JBM (Healthcare) Ltd. The record holds 183 filings, for trades running from 20 September 2017 to 22 January 2026.

Market trades split into 160 purchases (€61.5M) and 8 sales (€5.0M). The totals do not cover 17 filings with an undisclosed amount. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. In 2026 alone, the filings show no purchases and 1 sale.

A typical purchase (the median) is worth €39k. Clusters matter here: 23 out of 146 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster. After 146 purchases with a full 90-day history, the hit rate stands at 35% and the median 90-day move at -5.3%. They describe history only and say nothing certain about the share price ahead.

The record was last updated on 23 January 2026 with an open-market sale (€1.3M) in JBM (Healthcare) Ltd. The last insider purchase was made public on 8 December 2025, 317 days ago. Between a trade and the moment it shows up on HKEX, the median delay is 1 day. That lag is the time during which only the insider knows about the trade. These figures are compiled from regulatory filings published by HKEX. They describe what insiders did and are not a recommendation.
