Context
Sales executed under a Rule 10b5-1 plan are pre-established trading arrangements that schedule transactions in advance; they are common for insiders and are not by themselves a direct signal of the insider’s current view. For retail investors, purchases usually carry more informational weight than routine, pre-planned sales.
