Insiders at Byggmax Group AB

Shares is a position we rebuilt from reported transactions — not a disclosed balance.

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.

Value is that share count priced at the same closing price used everywhere else on this site. A row priced from only some of a person’s securities says so — we do not quietly present a partial sum as a complete one.

Recent insider transactions

Of the 156 rows we hold, 127 are open-market purchases (SACQ) and 12 open-market sales (SDIS) — the only codes we count as buying or selling.

The rest — awards, shares withheld to pay tax, option exercises, gifts and so on — follow from an employment contract or a transfer arranged off-market, not from a decision to buy or sell, so counting them would turn this into a pay table.

A price of 0.00 is a real reported figure on allotments, gifts and option exercises — not a gap in our data.

Sources and technical notes

Every figure on this page comes from insider transaction reports filed to Finansinspektionen (FI) in Sweden. Nothing here is estimated, and nothing is taken from press coverage or company websites.

How the positions on this page were built. 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.
