Context

• Sales to cover tax withholding after RSU vesting and trades executed under a 10b5‑1 plan are common and routine for insiders and do not necessarily indicate a change in view on the company. For retail investors, purchases are generally more informative as potential signals; these reported transactions are dispositions and largely administrative in nature.
