Zhang Buzhen: trading record in brief
Zhang Buzhen is a declared insider of YSB Inc. (chief executive), with filings sourced from HKEX. We count 7 filings; the first trade dates from 6 November 2024 and the latest from 29 May 2026.
Every open-market trade on record is a purchase: 7 purchases worth €466k, and no sale. No amount is published for 2 filings, which the totals therefore leave out. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. In 2026 alone, the filings show 6 purchases and no sales.
In size, the median ticket on the buying side is €91k. Measured against the company's value, the median purchase equals 0.034% of market capitalisation, across 5 purchases where it is known. The 6 purchases reviewed show no overlap with other insiders buying the same stock within a month.
On 1 June 2026 came the latest disclosure, an open-market purchase for €191k in YSB Inc. Filings reach the HKEX feed a median of 4 days after the trade. Until a filing is published, the market cannot know about the trade. Every figure here comes from the filings published by HKEX and describes the past, not future prices; it is not investment advice.
