Carl Östring

Carl Östring (board member) discloses dealings in 2 companies, chiefly Drillcon Aktiebolag and SenzaGen AB. In total, 91 filings cover trades dated from 23 May 2017 to 22 September 2025.

Both buying and selling appear: 89 purchases worth €243k, against 2 sales worth €26k. On balance, insiders were net buyers of €216k. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. In 2025 alone, the filings show 7 purchases and no sales.

In size, the median ticket on the buying side is €1,457. Clusters matter here: 4 out of 87 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 newest entry dates from 22 September 2025: an open-market purchase of €855, in Drillcon Aktiebolag. Typically, a trade is published a median of 1 day after it takes place. The regulation allows three business days to notify a trade (MAR article 19). These figures are compiled from regulatory filings published by Finansinspektionen. They describe what insiders did and are not a recommendation.
