Context

  • A Rule 10b5-1 plan lets insiders sell according to a pre-set schedule and is commonly used to avoid questions about timing; it does not necessarily signal a change in insider sentiment.
  • These were open-market sales (routine disposition of shares), which are less informative than purchases about an insider’s confidence in the company.
