Zhang Jianguo

Zhang Jianguo discloses dealings in 2 companies, chiefly Renrui Human Resources Technology Holdings Ltd. and Haitian International Holdings Ltd. We count 32 filings; the first trade dates from 26 June 2018 and the latest from 10 September 2026.

The open-market side counts 20 purchases for €1.7M alongside 10 sales for €169k. The amount is not disclosed for 7 filings. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Since January 2026: no purchases and 7 sales on the market.

Half of the purchases are above €53k and half below. 16 out of 16 purchases came within 30 days of a purchase by at least one other insider of the same company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

Most recently, on 15 September 2026, the filings show an open-market sale worth €21k in Renrui Human Resources Technology Holdings Ltd. The last purchase on record was published on 29 July 2025, which is 452 days ago. Typically, a trade is published a median of 5 days after it takes place. The shorter that gap, the sooner other investors can see what insiders have done. Every figure here comes from the filings published by HKEX and describes the past, not future prices; it is not investment advice.
