Justine Campbell: trading record in brief
Justine Campbell discloses dealings in National Grid plc to RNS (LSE). Over a trading history stretching from 21 June 2021 to 24 June 2025, the count stands at 12 filings.
Both buying and selling appear: 10 purchases worth €316k, against 2 sales worth €1.1M. The amount is not disclosed for 5 filings. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. In 2025 alone, the filings show 2 purchases and no sales.
A typical purchase (the median) is worth €70k. Clusters matter here: 8 out of 8 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. Looking at 3 purchases old enough to measure, the stock rose over the following 90 days in 33% of cases; the median change was -0.6%. Past outcomes like these are no guarantee of what comes next.
The newest entry dates from 24 June 2025: an open-market purchase, in National Grid plc. Most trades are made public on the day they happen. The regulation allows three business days to notify a trade (UK MAR). Source: insider filings from RNS (LSE). Past trades are no guide to future returns.
