Context Sales to cover tax withholdings on vested restricted stock units are common and do not necessarily reflect the insider’s view of the company’s prospects. Gifts to a DAF are also routine charitable actions and are not a direct signal of market sentiment. Purchases generally carry more weight as bullish signals; this filing reflects a sale for tax purposes and a charitable donation.
