Context Sell-to-cover transactions are routine administrative sales that occur when restricted stock units vest and some shares are sold automatically to pay required taxes. Such sales are generally viewed as tax-related compliance actions rather than a direct statement of the insider’s view on the company’s stock. Retail investors should consider this alongside other insider activity and company fundamentals.
