Context This was a routine sell-to-cover tied to RSU vesting — a common administrative transaction to meet tax obligations and generally not considered a sentiment-driven trade by the insider. Retail investors typically treat such tax-withholding sales differently from discretionary insider purchases, which can be a stronger signal of insider conviction.
