Filings by Zhang Bin span 3 companies, the busiest being Edianyun Ltd., AK Medical Holdings Ltd. and China Chengtong Development Group Ltd. The record holds 24 filings, for trades running from 20 December 2017 to 10 July 2026.

The open-market side counts 17 purchases for €95.6M alongside 3 sales for €210.5M. The amount is not disclosed for 8 filings. 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 11 purchases and no sales.

The median purchase comes to €8,505. As a share of market capitalisation, the median purchase stands at 0.0051%, based on 7 purchases. 5 out of 13 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster. Looking at 8 purchases old enough to measure, the stock rose over the following 90 days in 38% of cases; the median change was -0.7%. This is a record of the past, not a forecast.

The latest filing, published on 16 July 2026, reports an open-market purchase in Edianyun Ltd. Filings reach the HKEX feed a median of 5 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.
