Jacob Karlsson AB: trading record in brief
All filings by Jacob Karlsson AB on record concern K-Fast-B (K-Fast Holding AB). Between 28 July 2022 and 17 January 2026, the trades on record add up to 10 filings.
On the market, this insider has only ever bought: 8 purchases, €2.5M in total. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.
In size, the median ticket on the buying side is €190k. Clusters matter here: 7 out of 8 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.
The latest filing, published on 17 January 2026, reports a transaction in K-Fast-B (K-Fast Holding AB). The clock since the last published purchase (5 October 2023) now reads 1,130 days. Publication is fast: at least half of the trades appear on Finansinspektionen on the same day. Under the Market Abuse Regulation, managers have three business days to notify their trades. These figures are compiled from regulatory filings published by Finansinspektionen. They describe what insiders did and are not a recommendation.
