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.
