SinoMab BioScience Ltd. - B: what insiders have been doing
This page follows insider dealings at SinoMab BioScience Ltd. - B as filed with HKEX, a company from the Health Care sector. Over the twelve months to 8 November 2026, 3 filings were filed, from 1 insider.
No insider sold shares on the market over the period. Instead, the filings list 1 purchase, made by 1 insider. The totals do not cover 1 filing with an undisclosed amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The buyers include 1 senior executive.
The most recent open-market purchase was published on 29 July 2026, 102 days ago. Typically, a trade is published a median of 5 days after it takes place. That lag is the time during which only the insider knows about the trade.
Across the 1,323 companies tracked on its exchange, the median is 4 filings; at 3 filings, this issuer sits below that mark. Looking back to 2019, when coverage begins, insiders filed 10 purchases and 14 sales.
For comparison within the same sector, see the insider buying recorded at Dynavox Group AB and Vetoquinol SA. Every figure here comes from the filings published by HKEX and describes the past, not future prices; it is not investment advice.
