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 5 filings in this group are Form 4s for MediWound Ltd.
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 5 insider filings shown, the breakdown is 3 open-market purchase, 1 mixed open-market activity and 1 open-market sale. 5 of them involved a discretionary open-market trade; the rest are compensation and administrative mechanics.
What each transaction type means
- Open-market purchase ×3
- The insider bought shares on the open market with their own money. This is the only Form 4 category that requires a discretionary cash outlay at the prevailing price.
- Mixed open-market activity ×1
- The filing reports both purchases and sales on the open market. Read the transaction lines individually before drawing a directional conclusion.
- Open-market sale ×1
- The insider sold shares on the open market. Sales may be discretionary or executed automatically under a pre-arranged Rule 10b5-1 trading plan, and a Form 4 does not always make clear which applies.
