Context
Sales under Rule 10b5-1 plans are pre-arranged and commonly used by insiders to liquidate shares on a schedule; they are often routine and do not necessarily signal a change in outlook. For retail investors, purchases by insiders tend to be more directly informative about confidence in the business than routine plan-based sales.
