Margaret E Southern: trading record in brief
Margaret E Southern discloses dealings in Atco Ltd. to SEDI. Between 31 October 2016 and 11 December 2025, the trades on record add up to 113 filings.
Purchases make up the whole of the open-market record (107 purchases, €22.0M). Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The rest of the record consists of 1 share grant. In 2025 alone, the filings show 26 purchases and no sales.
In size, the median ticket on the buying side is €155k. None of the 80 purchases we analysed coincided with buying by another insider of the same company within 30 days.
On 15 December 2025 came the latest disclosure, a transaction in Atco Ltd. The clock since the last published purchase (10 December 2025) now reads 315 days. The median gap between a trade and its publication by SEDI is 1 day. That lag is the time during which only the insider knows about the trade. Every figure here comes from the filings published by SEDI and describes the past, not future prices; it is not investment advice.
