Context This was primarily a routine RSU vesting event with shares withheld to cover taxes plus a small open-market sale. The RSU conversion was not a cash exercise (no purchase price), and the withholding sale is a common administrative step that doesn’t necessarily indicate a change in insider sentiment. The 13-share sale ($2.8k) is small relative to typical insider trades and should be viewed as routine liquidity/tax-related activity rather than a strong market signal.
