Magnus Larsson

Magnus Larsson (chief executive) discloses dealings in 3 companies, chiefly Promimic AB, Alcadon Group AB and Diadrom Holding AB. Over a trading history stretching from 19 March 2025 to 18 March 2026, the count stands at 12 filings.

The open-market record is one-sided, with 12 purchases worth €37k and not one sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. 2026 to date brings 3 purchases and no sales.

A typical purchase (the median) is worth €1,774. Measured against the company's value, the median purchase equals 0.0099% of market capitalisation, across 11 purchases where it is known. Of 12 purchases, 3 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

Most recently, on 18 March 2026, the filings show an open-market purchase worth €3,081 in Promimic AB. Publication is fast: at least half of the trades appear on Finansinspektionen on the same day. The legal deadline for notifying a trade is three business days (MAR article 19). These figures are compiled from regulatory filings published by Finansinspektionen. They describe what insiders did and are not a recommendation.
