No net buyers or sellers account for the net balance. There is no cluster of three distinct buyers within 30 days. We found 1 CEO/CFO purchases over 12 months.

How to read this signal

Form 4 raw → Raspberry

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.
