POWER SOLUTIONS INTERNATIONAL, 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 no 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.

Each Phantom Unit represents an unfunded, unsecured right to receive a cash payment equal to the average Fair Market Value per share of the Issuer's Common Stock over the thirty (30) trading days immediately preceding the applicable vesting date. Phantom Units are settled in cash only and do not entitle the Reporting Person to any shares of Common Stock or voting rights. One-third of the Phantom Units vest on each of August 17, 2027, August 17, 2028 and August 17, 2029, subject to the Reporting Person's continuous service with the Issuer or its affiliates.

Raspberry interpretation
Informational — no alert

Reason: administrative_code.
