Context
This is a routine "sell-to-cover" (forfeiture) to satisfy tax withholding for vested RSUs and does not necessarily indicate the insider's view on the company's stock. Purchases generally carry more interpretive weight for bullish signals; withholding/forfeiture transactions are common after vesting events.
