No insider purchase over the last 90 days. The latest, by Sue Nyman, was filed 08 May 2026.
This page follows insider dealings at Judges Scientific plc as filed with RNS (LSE), a company from the Technology sector. 11 insiders have disclosed 82 filings since 21 October 2025.
Every open-market trade in the period is a purchase: 4 purchases worth €39k, from 4 insiders, and not a single sale. The amount is not disclosed for 2 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The buyers include 2 finance chiefs, 1 board member and 1 chief executive. At €32k, the purchase published on 7 April 2026 by Tim Prestidge is the largest of the period.
Compared with its exchange (832 companies, median 6 filings), a count of 82 filings is above the norm. The full history, which starts in 2016, counts 23 purchases against 20 sales.
Within a 30-day window, 3 purchases overlapped with buying by a second insider. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. The last purchase on record was published on 8 May 2026, which is 166 days ago. Between a trade and the moment it shows up on RNS (LSE), the median delay is 4 days. Under the UK Market Abuse Regulation, managers have three business days to notify their trades.
This summary is built from RNS (LSE) 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.
