A Form 4 is filed within two business days of a company insider — an officer, a director, or a holder of more than ten percent of the stock — changing their position in the shares. All 7 filings in this group are Form 4s for CoinShares PLC.
The difficulty with reading these filings as a group is that a single form type covers transactions that mean entirely different things. An executive spending their own money to buy stock and an executive having shares withheld to pay tax on a vesting grant both appear as a Form 4. Every filing below is therefore tagged with the nature of the underlying transaction, taken from the transaction code reported on the form itself.
Across the 7 insider filings shown, the breakdown is 3 other reported transaction, 3 open-market sale and 1 option exercise. 3 of them involved a discretionary open-market trade; the rest are compensation and administrative mechanics.
