Context A "sell to cover" is a common mechanism where an employer requires a portion of vested RSUs to be sold to cover taxes; it generally does not indicate the insider's view on the company's prospects. For retail investors, purchases typically signal more actionable insider conviction than routine, mandatory sales like this one.
