Simon De Chateau: trading record in brief

This profile gathers the share dealings of Simon De Chateau in Atrium Ljunbgerg AB. Over a trading history stretching from 19 December 2017 to 23 October 2026, the count stands at 21 filings.

On the open market, the record shows 10 purchases worth €660k and 11 sales worth €864k. The totals do not cover 2 filings with an undisclosed amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. 2026 to date brings 1 purchase and no sales.

The median purchase comes to €86k. Clusters matter here: 6 out of 6 purchases overlapped with buying by a colleague within 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

On 23 October 2026 came the latest disclosure, an open-market purchase for €97k in Atrium Ljunbgerg AB. Between a trade and the moment it shows up on Finansinspektionen, the median delay is 2 days. Under the Market Abuse Regulation, managers have three business days to notify their trades. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. These figures are compiled from regulatory filings published by Finansinspektionen. They describe what insiders did and are not a recommendation.
