YSB Inc.: what insiders have been doing
Every trade that managers of YSB Inc. disclose to HKEX is tracked on this page. The company sits in the Health Care sector. Over the twelve months to 22 October 2026, 12 filings were filed, from 2 insiders.
The flow runs one way only: 2 insiders bought (12 purchases totalling €1.2M) and nobody sold on the market. No amount is published for 2 filings, which the totals therefore leave out. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Biggest ticket of the year: €191k, bought by Zhang Buzhen and made public on 1 June 2026 (0.064% of market cap). Those buying include 2 senior executives.
The clock since the last published purchase (1 June 2026) now reads 160 days. The median gap between a trade and its publication by HKEX is 1 day. This delay matters because a trade only becomes useful information once it is public.
Across the 1,314 companies tracked on its exchange, the median is 4 filings; at 12 filings, this issuer sits above that mark. Our records for YSB Inc. go back to 2023, with 22 purchases and 2 sales on the open market in total.
For comparison within the same sector, see the insider buying recorded at UCB. Every figure here comes from the filings published by HKEX and describes the past, not future prices; it is not investment advice.
