Reported transactions

Price 0.00 is a real reported figure on allotments, gifts and option exercises — not a missing number. The 25 most recent rows are grouped into 23 lines by date, company and transaction type — open a line to see every lot with its own source link. We hold 31 on file in total.

How to read this list

Every row is one insider transaction as reported to FI, with a link back to the FI register filtered to that issuer and publication date. FI publishes no per-report permalink, so the link is a search, not a document. Where the record carries no price at all we leave the cell empty instead of guessing one.

The shares and money on a grouped line add up only the lots listed inside that line, and only when every one of them carries the figure. Where a group mixes more than one reporting currency we leave the money blank rather than convert — no source publishes the rate that conversion would need.

Reconstructed positions

Reconstructed by adding up every transaction this person reported to FI since 2016. FI publishes transactions, not balances, so this is a computed figure, not a disclosed one — and it omits anything held before the register began.

What is not counted here

Each row comes from a public disclosure named on this page. Private companies, real estate, bonds and crypto are not in those disclosures and are therefore not counted here. Shares held through a holding company are recorded against that company, not against the individual behind it.

Equity positions reported to Finansinspektionen (FI) in Sweden, with the disclosure date shown on each row.

Other shareholders on record at the same companies

People who also appear on the shareholder record of a company where Claes Mellgren reports shares.

Sharing a filing does not mean they work together day to day — it means both names appear on the same issuer’s insider record.

Sources

Every figure on this page is quoted from the public record named beside it, with the date it was true. Nothing here is our own calculation.
