Tsai Joseph Chung

Tsai Joseph Chung, listed as chief executive, appears in our data through filings on Alibaba Group Holding Ltd. - W shares, published by HKEX. Between 21 February 2025 and 1 October 2026, the trades on record add up to 16 filings.

The open-market side counts 5 purchases for €17.7M alongside 4 sales. The amount is not disclosed for 7 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. So far in 2026, the count stands at 3 purchases and 1 sale.

2 out of 3 purchases came within 30 days of a purchase by at least one other insider of the same company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The newest entry dates from 6 October 2026: a transaction, in Alibaba Group Holding Ltd. - W. The latest purchase dates back some time: it was published 60 days ago, on 25 August 2026. The median gap between a trade and its publication by HKEX is 5 days. That lag is the time during which only the insider knows about the trade. These figures are compiled from regulatory filings published by HKEX. They describe what insiders did and are not a recommendation.
