Context Sales executed under a pre-established 10b5-1 plan are typically scheduled trades and are often treated as routine rather than a direct signal of the insider’s view on the company. For retail investors, purchases are generally more informative about insider sentiment than scheduled sales; these transactions simply record that a director liquidated a block of shares under an existing plan.
