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 11 filings in this group are Form 4s for Protara Therapeutics, Inc.
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 11 insider filings shown, the breakdown is 8 compensation award, 2 open-market sale and 1 tax withholding. 2 of them involved a discretionary open-market trade; the rest are compensation and administrative mechanics.

Shefferman Jesse, listed as Director, CEO and President at Protara Therapeutics, Inc., reported an open-market sale of 215,687 TARA shares in a Form 4 filing. This is a confirmed insider sale, not just a proposed sale notice.
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.
