Nancy C. Southern: trading record in brief

Nancy C. Southern appears in our data through filings on Atco Ltd. shares, published by SEDI. Between 9 January 2003 and 11 December 2025, the trades on record add up to 288 filings.

In open-market terms, that means 114 purchases worth €22.8M on one side and 92 sales worth €10.3M on the other. Taken together, the purchases exceed the sales by €12.5M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 50 share grants and 8 option exercises. In 2025 alone, the filings show 26 purchases and 57 sales.

A typical purchase (the median) is worth €155k. Across 85 purchases, this insider has always bought alone, with no colleague buying within 30 days.

The newest entry dates from 15 December 2025: a transaction, in Atco Ltd. The latest purchase dates back some time: it was published 315 days ago, on 10 December 2025. The median gap between a trade and its publication by SEDI is 2 days. That lag is the time during which only the insider knows about the trade. Source: insider filings from SEDI. Past trades are no guide to future returns.
