Context Sell-to-cover transactions are common when restricted shares vest and the company or insider must satisfy tax withholding; they are generally considered routine and do not necessarily signal a change in insider sentiment. For retail investors, purchases or voluntary large open-market buys by insiders tend to be more informative than mandatory sell-to-cover disposals.
