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.

Represents shares of common stock sold to cover the Reporting Person's tax liability from the vesting of restricted stock awards previously granted to the Reporting Person that fully vested in connection with the terms of the Agreement and Plan of Merger, dated as of August 20, 2024, by and among Core Natural Resources, Inc. (formerly known as CONSOL Energy Inc.), Mountain Range Merger Sub Inc. and Arch Resources, Inc. Of the 21,830 shares reported, 4,576 are unvested restricted stock units.
Raspberry interpretation
Informational — no alert
Reason: tax_withholding. The filing footnotes identify tax withholding.
Recent transactions
Voluntary purchases and sales; administrative noise stays hidden.
