William Whitehorn discloses dealings in Seraphim Space Investment Trust plc to RNS (LSE). We count 8 filings; the first trade dates from 12 May 2026 and the latest from 26 June 2026.

The open-market record is one-sided, with 8 purchases worth €541k and not one sale. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.

Half of the purchases are above €11k and half below. Relative to company size, the median is 0.0026% of market cap (8 purchases with a known value). Of 6 purchases, 6 formed part of a group of insiders buying within 30 days of each other. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

Most recently, on 26 June 2026, the filings show an open-market purchase worth €11k in Seraphim Space Investment Trust plc. Half of the filings or more reach the RNS (LSE) feed on the day of the trade. The legal deadline for notifying a trade is three business days (UK MAR). Source: insider filings from RNS (LSE).
