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.

This Form 4 reports the withholding of shares to satisfy withholding tax obligations upon the vesting of restricted stock units which were previously granted and reported. The change in share ownership of the Reporting Person reported in this Form 4 results from the difference between (i) the number of restricted stock units subject to vesting that were previously granted and reported and (ii) the net number of shares actually received upon vesting of such restricted stock units after the withholding of shares to satisfy withholding tax obligations. This does not reflect an open market sale of securities.
Recent transactions
Voluntary purchases and sales; administrative noise stays hidden.
