Company rankings
Public companies ranked by market capitalisation, next to the value of the stake held by the officers, directors and major shareholders who disclose their holdings in that company.
How each cap is worked out
Shares outstanding as reported by the company — to the U.S. Securities and Exchange Commission, to Finansinspektionen (FI) in Sweden, or under Vietnam's listed-company ownership rules — multiplied by the closing price on the date shown against each figure. We compute every cap here ourselves; none is copied from a ranking published by anyone else. Companies we hold only through the Swedish insider register have no cap here: that register lists insider transactions, not the issuer’s share count.
Compiled from cited public records — every figure names the disclosure it came from, none copied from any wealth ranking. Dataset . How we calculate this.

3 of these 109 companies carry no market cap and sit at the end of this ranking. Blank means we do not know — never zero, and never a guess.
The four reasons a cap is left blank
A cap is left blank whenever we cannot stand behind the arithmetic: the company lists more than one class of common stock and its filings do not say which one the reported shares belong to; it files as a foreign private issuer, whose shares are reported in ordinary shares while the listed security is an ADS at a ratio the filings never state; the SEC’s own ticker directory does not carry the company; or the newest share count on file is too old to call a current market cap.

Why two figures on one row can carry different dates
Market cap and insider-held value are computed separately and can carry different dates, which is why each figure shows its own.
