No insider purchase over the last 90 days. The latest, by Li Dun, was filed 11 May 2026.
Wison Engineering Services Co. Ltd., classified in the Industrials sector, is a listed company. Its insiders report their share dealings to HKEX. The last twelve months, up to 19 October 2026, brought 12 filings signed by 6 insiders.
On the market, 3 insiders bought (3 purchases) while 3 insiders sold (3 sales totalling €23k). The totals exclude 3 filings filed without an amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The buyers include 3 senior executives. One trade stands out by size: a sale of €11k from Zhou Hongliang, disclosed on 13 April 2026, or 0.0059% of market capitalisation.
The latest purchase dates back some time: it was published 163 days ago, on 11 May 2026. The median gap between a trade and its publication by HKEX is 6 days. Until a filing is published, the market cannot know about the trade.
Compared with its exchange (1,147 companies, median 5 filings), a count of 12 filings is above the norm. Over the whole record (from 2017), the tally stands at 24 purchases and 11 sales.
For comparison within the same sector, see the insider buying recorded at Tennant Co and Butler National Corp. This summary is built from HKEX disclosures alone and does not predict where the share price will go.
Entry is the close on the day after publication, the first price a reader could act on. Prices in the listing currency. Past moves are not a forecast.
This score ranks the purchase within its own market. A position size is suggested only on the venues of the backtested strategy universe; elsewhere, signals stay on watch. Not investment advice.
Transparent value + quality ranking, distinct from the insider signal.
