Antti Mäkinen

Antti Mäkinen is a declared insider of Sampo (board member), with filings sourced from Nasdaq Helsinki. The record holds 4 filings, for trades running from 9 November 2023 to 12 February 2026.

The open-market record is one-sided, with 4 purchases worth €211 and not one sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. So far in 2026, the count stands at 1 purchase and no sales.

Half of the purchases are above €52 and half below. Scaled by market value, the purchases weigh a median 0.0000% of market cap (sample: 4 purchases). 3 out of 4 purchases came within 30 days of a purchase by at least one other insider of the same company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

The latest filing, published on 13 February 2026, reports an open-market purchase of €45 in Sampo. The median gap between a trade and its publication by Nasdaq Helsinki is 1 day. The regulation allows three business days to notify a trade (MAR article 19). Source: insider filings from Nasdaq Helsinki. Past trades are no guide to future returns.
