DELCATH SYSTEMS, INC.

No net buying or selling imbalance over the last 3 months

No net buyers or sellers account for the net balance. There is no cluster of three distinct buyers within 30 days. We found 3 CEO/CFO purchases over 12 months.

How to read this signal

Only open-market P purchases and S sales count toward the signal. Vesting, options, taxes and gifts remain in the source data but do not trigger alerts. Rule 10b5-1 trades are shown as informational.

Form 4 raw → Raspberry

The value is in what we do not call a signal.

The SEC XML stores every transaction. Raspberry keeps that evidence, reads the footnotes and separates voluntary open-market activity from vesting, option exercises, gifts, tax withholding, stock purchase and dividend reinvestment plans and pre-programmed 10b5-1 trades.

The option will vest and become exercisable at the rate of one-twelfth (1/12th) per month with the first such vesting to occur on May 13, 2026 and monthly thereafter for so long as the reporting person remains a director of the Issuer (and subject to the terms and conditions of the Issuer's 2020 Omnibus Equity Incentive Plan, as amended). The option will expire the earlier of 10 years from the grant date or, for vested options, two years from the last day of service.

Raspberry interpretation
Informational — no alert

Reason: administrative_code.
