Zheng Shifeng

Zheng Shifeng (chief executive) discloses dealings in Wison Engineering Services Co. Ltd. to HKEX. Over a trading history stretching from 1 September 2020 to 8 May 2026, the count stands at 8 filings.

On the open market, the record shows 4 purchases worth €18k and 2 sales worth €5,858. No amount is published for 3 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. So far in 2026, the count stands at 1 purchase 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. Purchases made close together by different insiders form what is called a cluster.

The record was last updated on 11 May 2026 with an open-market purchase in Wison Engineering Services Co. Ltd. Filings reach the HKEX feed a median of 4 days after the trade. The shorter that gap, the sooner other investors can see what insiders have done. Source: insider filings from HKEX. Past trades are no guide to future returns.
