Context

• A "sell-to-cover" is a routine transaction where the company (or issuer election) sells a portion of vested shares to cover payroll/tax withholding; such sales are common and do not necessarily indicate the insider's view of the company. Purchases generally carry more weight as signals than routine withholding sales.
