Guy Walker: trading record in brief

Guy Walker appears in our data through filings on Impax Environmental Markets plc shares, published by RNS (LSE). The record holds 3 filings, for trades running from 9 December 2024 to 19 May 2026.

Both buying and selling appear: 1 purchase worth €24k, against 2 sales worth €131k. The totals exclude 1 filing 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. 2026 to date brings no purchases and 2 sales.

Most recently, on 19 May 2026, the filings show an open-market sale worth €131k in Impax Environmental Markets plc. The most recent open-market purchase was published on 9 December 2024, 699 days ago. The median gap between trade and publication is zero days: most filings appear on the same day. For comparison, UK MAR gives managers three business days to notify a trade. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Every figure here comes from the filings published by RNS (LSE) and describes the past, not future prices; it is not investment advice.
