Context
A sell‑to‑cover tied to RSU vesting is a routine administrative sale to pay taxes and is not the same as a discretionary open‑market sale that might indicate a change in sentiment. For retail investors, purchases or large discretionary sales by insiders are generally more informative than automated tax‑withholding transactions.
